On dissociation, it gives proton ion which is also colourless and rest molecule possesses deep pink colour. HPh → H + + Ph – As the concentration of hydrogen ion increases, dissociation of HPh decreases up to nill. So the solution is colourless.

It is a dibasic acid, with pKas of 2.89 and 5.51. The monopotassium salt, potassium hydrogen phthalate is a standard acid in analytical chemistry. Typically phthalate esters are prepared from the widely available phthalic anhydride. Reduction of phthalic acid with sodium amalgam in the presence of water gives the 1,3-cyclohexadiene derivative.
WebPotassium hydrogen phthalate (KHP) is a semi-organic salt that is a member of the alkali acid phthalate series. KHP crystals are useful in devices because of their electro-optical properties. It usually acts as a model compound due to its well-developed surface pattern on the (010) face that can be easily observed by optical microscopy.
