CHY 123 Determination of the Equilibrium Constant Introduction Neutralization reactions between bases and the protons from acids are the driving force behind acid-base reactions. By measuring the amount of protons an acid donates to a reaction is a measure of how powerful the acid is. If an acid donates a low amount of protons then it is considered a weak acid and the opposite is true about strong acids. By measuring the equilibrium point of an acid base reaction the equilibrium constant can be determined. Procedures We gathered the needed chemicals and containers needed for the experiment. we set up our buret so that we could add NaOH to the beaker while a stirrer was sitting underneath it. We then filled one buret with the acid and the other with the NaOH. We added 25ml of our acid into a beaker along with 75ml of distilled water and a few drops of the indicator solution. We then recorded the pH of the solution using the pH indicator instrument. We then proceeded to turn on the stirrer and started to add the NaOH to the acid beaker in
