DETERMINATION OF POTASSIUM HYDROGEN PHTHALATEAND UNKOWN SODIUM CARBONATE

Introduction

The two types of aqueous solutions in chemistry that are being experimented with are called acids and bases. A strong acid solution is one that consists of a solution that is less than seven ph factor. The basic solution is one that consists of greater than seven on the ph scale. In this experiment standardization of a chemical reaction is used to determine the concentration of the acid and the base solution. Potassium Hydrogen Phthalate (KHP) mixed with Sodium Hydroxide (NaOH) is a good source of standardization. In the solution of KHP and water add the Sodium Hydroxide by titrating using a buret. This can give you the point where the acid has been neutralized. The point of neutralization is referred to as the ending point The chemical equation used to indication this point is shown in reaction 1.
HIn +H20 H30 +In- (1)
An indicator used for this experiment was phenolphthalein which has a transition range of 8.3 to 10.0 and its color chang...
