Salt hydrolysis

This kit enables to study the salt hydrolysis; the salt hydrolysis consists of a full or partial recombination of ions of a salt into molecules: that occurs when this salt comes out from a base and an acid of different strength, or from a base and an acid being both weak. The test develops in four phases; in all the four phases a spatula full of salt is plunged into distilled water and salt is dissolved; then a universal indicator paper is immersed and pH is measured.
