Q1ChemistryUnit 20: Principles Related to Practical Chemistry
A student takes about 4ml4 \mathrm{ml} of distilled water in four test tubes marked P,Q,RP, Q, R and S.S . He then dissolves in each test tube, an equal amount of various salts, viz. sodium sulphate in P,P, potassium sulphate in Q,Q, calcium sulphate in RR and magnesium sulphate in SS. After that, he adds an equal amount of soap solution in each test tube. On shaking each of these test tubes well, he observes a good amount of lather (foam) in the test tube marked:
