Results 10 Calculations 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

Thermochemistry (((CLASS INFORMATION)) INTRODUCTION Thermal chemistry was intended to display that chemical reaction and phase changes involve energy. The energy of heat was presented when a change in temperature difference was evaluated. Chemical reactions in a calorimeter were used to determine the amount of heat produced by a reaction. Reactions that absorb heat were noted as endothermic‚ and reactions that release heat were noted as exothermic

Can you catch more flies with honey than with vinegar ? Positivity or optimism is something observed in the field of psychology that refers to two phenomena: That people tend to observe a neutral situation as mildly positive‚ or that people feel good at any given moment and this is easily observable to other individuals around a person.

samples of vinegar if any had been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere

Vinegar and soap as an Alternative Weed Killer Introduction A. Background of the study Since ancient times‚ vinegar has been used for different purposes like cleaning‚ cooking‚ gardening‚ etc. In gardening‚ it is used as a herbicide. Vinegar is an important element in organic gardening‚ as it has the capability of killing the weeds. Vinegar contains natural acetic acid which helps in destroying the weeds. Acetic acid (systematically named ethanoic acid is an Acetic acid (systematically

Pineapple (Ananas comosus) peeling as a major component in making vinegar to reduce post-harvest loss of pineapple and to promote the safe and positive effects of using pineapple peeling as a major component in making vinegar. This study is helpful to the environment because it reduces pineapple waste which contains residual pulp‚ peels that can cause environmental pollution problems if not utilized. Another is that the vinegar made out of pineapple peelings is natural and less acidic than the

can this be prevented? Does acid rain have effects on not only the environment‚ but the plants and animals that inhabit it? Hypothesis: If vinegar (a substitute for acid rain) is poured over building materials‚ then left to dry‚ the researcher believes that vinegar (acid rain) will cause the building materials to be affected because vinegar (acid rain) has chemicals that are known to destroy many structures in the environment. Variables: Independent variable: building material (marble
