Question

The floclulation values of KCl,MgCl2,CrCl3 andSnCl4 for a negatively charged sol are in order of

Answer 1

Answer: The order is

SnCl4 > CrCl3 > MgCl2 > KCl

Explanation

Higher the valency higher is the capability coagulate the colloid. ~ HARDY SCHULZ RULE.

Answer 2

The order of flocculation values are of the order $SnCl4 > CrCl3 > MgCl2 > KCl$

Explanation:

The flocculation value can be explained by Hardy Schulz Rule.

According to the Hardy Schulz rule If higher is, the valency then higher is the capability to coagulate the colloids

The greater the valency of a flocculating ion, the greater is the capability for the power to cause precipitation.

This rule states that when the amount of electrolyte required for coagulation is in definite amount of a colloidal solution.

It will be dependent on the valency of the coagulating ions

The coagulating ion is indefinite is the ion that has the charge of the colloidal particles.
