It’s practically impossible to imagine life without water. Carbon (18%) is synonymous with life. Its central role is due to the fact that it has four bonding sites that allow for the building of long‚ complex chains of molecules.

14 Discussion 20 Conclusion 21 Recommendations 21 References 22 Appendices 22 Abstract This experiment was performed in order to determine the molarity of a solution and the percent by mass of acetic acid‚ CH3COOH in vinegar. Acetic acid is monoprotic and belongs to the carboxyl family of organic compounds. The titration method is used to neutralize the acids by using the standardized sodium hydroxide solution. It reacts with bases which is sodium hydroxide‚ NaOH to form salt and water.

chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds were mixed together by the
