Titration method is a technique where solution of known concentration is used to determine the concentration of unknown solution. Typically the “Titrant” is known solution which is added in pipette, and “Analyte” is the unknown solution which is added in burette. Bases are the substance that dissolves in water to release (OH−) into a solution. Bases are classified into two types that are weak base and strong base. This is according to  whereby strong base is substance which is ionized completely to form (OH−) ions as only negative charge when in solution. Example: (K2CO3) from wood ashes. Weak base is substance which is ionized slightly to form (OH−) ions as only negative charge when in solution. Example: ammonium hydroxide.
Acid is a compound that can form hydrogen ions when dissolving in water to release (H+) ions into solution as only positive charge ion. Acid is classified into two types that are weak acid and strong acid. According to  whereby weak acid is substance which is ionized partially when dissolved in a solution. Example: (C6H8O7) citric acid from lemon fruits. And strong acid is substance which is ionized completely when dissolved in a solution. Usually the titration of strong base and week acid use phenolphthalein indicator, locally indicator prepared from a Red Cabbages, hence an indicator is substance which changes color during the titration .
Generally acidic and basic titration goal is usually to use the substance of known concentration to determine the concentration of unknown concentration of the other substance .
Locally available materials: these are the materials which are (household materials) or sometimes called as low cost materials. In this titration the materials used are lemon as weak acid and wood ashes as strong base; note lemon produce (citric acid), wood ashes produce (potassium hydroxide) and red cabbages (as an indicator) [Figure 1].
The titration of weak acid and strong base are very common in secondary schools; thus it is why we concentrate on it. Due to expensiveness of chemicals substance (solution) like (K2CO3) and other acids like citric acid, we decided to use locally available materials on making the proceeding of titration in secondary school with low coast. Therefore different authors and scholars explain many titrations, by using the other chemical substances from industries which are very expensive and toxic.
, defined process of determining the concentration of dissolved substance in terms of the smallest amount, of reagent known concentration required to bring about a given effect in chemical reaction with a known about volume of the lest solution.
, defined titrimetry is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte, a known concentration and volume of titrant reaction with a solution of analyte or titrant to determine with a solution of analyte or titrant to determine concentrations .
2. Materials and Methodology
2.1. Methodology Used
Methodology according to Dictionary.com methodology is asset or system of method, principle and rule for regulating and given discipline, as in art or science. According to Merriem-webster.com  is a body of methods, rules and postulates employed by discipline.
The followings are the methods that may be used over this project concerning this are:
• Extraction Method
• Preparation Method
• Titration Method
Extraction Method is a way of separating desirable substance when it is mixed with other. The mixture is brought into contact with solvent in which the substance of interest is soluble but the other substances are insoluble. Example extraction of K2CO3 (potassium carbonate) from hard wood Ashes based in research concerning.
Basic solution (K2CO3).
Before the preparation of basic solution we must first prepare the potassium carbonate salt, from the hard-wood ashes.
Preparation Method is a process of making and designing the possible things, in order to do experiments. Example preparation of Lemon Juice from (Lemon), and Preparation of Red cabbage solution from (Red-cabbage).
Titration Method is a technique or process of estimating or determining unknown concentration from known concentration, or is all about Titrant, Analyte and Indicator which used to show color changes when in each mentioned. Example determination of unknown Lemon Juice Concentration by titrating with Potassium carbonate solution with help of Red-cabbage indicator  .

Usually basic having characteristics of bitter and slippery, most of the basic substances are strong few of them is weak. The following are the source of strong Base: Hard & soft wood-Ashes, gypsum, coconut, Banana fruits, Pawpaw Steam and Leaves, mushroom, and water melon. Therefore in our project we deal with Hard-wood Ashes .

4) Then take the saucepan with the liquid out of the Heat source, and cool at room temperature.
5) After cooling filtrate again the solution, and leaving precipitate behind.
6) Transfer the Filtrate solution into large beaker and Heat again until (3/4) of water evaporated, then take out from the heat source and allow it to cool at room temperature.
7) Then after cooling filtrate again and take to the heat source and boil until all water Evaporated leaving the potassium carbonate salt on that Beaker. Then take it out from the sources.
8) Transfer the remained Sample into glass plate.
After preparing the potassium carbonate salt sample, the followings are the procedures of solution preparation of potassium carbonates in water:

4. Conclusions and Recommendations
Conclusion is an ending section which states the concluding ideas and conceptual of the proceeding writings. This generally follows the body or perhaps an afterword and the conclusion may be followed by an epilogue, outro and postscript.
According to the research concerning, it is concluded that in wood ashes, the best kind for many basic productions is hard wood-ashes (Ash from Timber, Big-Trees, Logs), rather than soft wood-ashes (Ash from grasses and papers).
Apart from all constituents present in wood-ashes like (sodium carbonate, potassium carbonate and other compounds like phosphorus, silicon), the common compound present in high concentration is Potassium Carbonate (K2CO3).
Based on investigation the only red-cabbage species is used as an indicator among the cabbage species. Due to that, red-cabbage contains the pigment or coloring agent called anthocyanin . This pigment is found in many flour fruits, fall leaves, and is responsible for many of the red blues and purple you see around you.
• Due to expensiveness of the sample-chemicals and indicators during the conduction of titration and other experiments, advice the government, should focus on locally available materials in order to develop other sample solutions, because it is possible.
• From the objective of titration to demonstrate the basic laboratory technique of titration and to learn how to calculate concentration based on titration, due to that as research member advice the government and private sectors to give the high support to all school teachers especially science teachers to use locally available materials in experiment in steady of advanced chemicals and give them motivation and reward for the best idea, this will help to high school performance in implementing curriculum and developing the students’ skills based on home available materials and also help to reduce the high cost required by the chemical from other countries or from industries.
• The government and private sectors should join together to conduct exhibition concern with creativity of the different teachers from different schools maybe region to region or district to district or ward to ward on how locally available materials are used as concretes’ materials in the implementing curriculum.
• Teachers of science should plan an inquiry-based science program for their students. These teachers should:
1) Develop a frame of the yearlong and short term goals for students.
2) Select science content and adopt and design curriculum to meet the interest, knowledge, understanding, ability and experience of students.
3) Select teaching and assessment strategies that support the development of the students’ understanding and nurture a community of science learners. Work together as colleagues within and across discipline and grade levels.
