Question

Provide the possible candidate ion/s for the primary adsorbed layer of a colloid formed when small amounts of silver nitrate is added to a solution of potassium chromate by accounting the following five factors: solubility, concentration, common ion, ion charge and ion size. Write the colloid formula.

Answer 1

Silver nitrate solution causes staining of skin and fabric (chemical burns). ... Then additional silver ions react with the chromate ions of the indicator, potassium chromate, to form a red-brown precipitate of silver chromate.
