That you are working with acids and bases. Cope with them with caution and clear up spills. Component one: Salts and Solution pH (proton transfer reactions in drinking water)

On the equivalence stage, the weak acid is consumed and transformed to its conjugate base. The pH will likely be better than 7 and may be calculated from an equation derived from the following associations: C a V a = C b V b displaystyle C_ a V_ a =C_ b V_ b

three. Poor and insufficient rinse of test tubes or dropper with distilled h2o could give erratic values of pH.

More accurately, an individual formula[3] that describes the titration of the weak acid with a robust base from start to complete is offered down below:
