Current Question (ID: 18424)

Question:

$\text{The coagulating power of an ion depends on:}$ $1. \text{The magnitude of the charge on the ion alone}$ $2. \text{Size of the ion alone}$ $3. \text{Both magnitude and sign of the charge on the ion.}$ $4. \text{The sign of the charge on the ion alone.}$

Options:

1. $\text{The magnitude of the charge on the ion alone}$
2. $\text{Size of the ion alone}$
3. $\text{Both magnitude and sign of the charge on the ion.}$
4. $\text{The sign of the charge on the ion alone.}$

Solution:

$\text{Coagulating power of an ion depends on the Nature of the charge and magnitude of charge.}$ $\text{For anion, +ve charge is needed and for cation -ve charge is needed.}$ $\text{So, option 3 is the correct answer.}$
