Question

which electrolyte has minimum flocculation value for the coagulation of fe2o3??xh2o sol?

Answer 1

Concentration of electrolyte required to coagulate a given amount of As2S3 sol is minimum in the case.

The coagulating power of an electrolyte for arsenious sulphide sol decreases in the order.

Preparation of AgI sol is excess of AgNO3 is added to potassium iodide solution.

Particles of the sol will acquire with sol has positively charged colloidal particles.
