Current Question (ID: 18451)

Question:

$\text{A colloid of AgI is formed by mixing AgNO}_3 \text{ with an excess of KI. The electrolyte with the greatest coagulation value for it is:}$

Options:

1. $\text{BaSO}_4$
2. $\text{NaCl}$
3. $\text{MgCl}_2$
4. $\text{Al}_2(\text{SO}_4)_3$

Solution:

$\text{Coagulating Power} \propto \frac{1}{\text{Coagulating Value}}$ $\text{Coagulating Power} \propto \text{Charge}$ $\text{Coagulating Value} \propto \frac{1}{\text{Charge}}$ $\text{Coagulating value increases as the charge decreases and vice-versa for Coagulating power of salt.}$ $\text{Since NaCl has the least charge cation and anion hence it has the highest Coagulating value.}$
