Explain the following:
Out of `BaCl_(2) and KCl` which one is more effective in causing coagulation of a negatively charged colloidal sol? Give reason.

Text Solution

Verified by Experts

The coagulation power increases with increase in charge on the ions used for coagulation. Thus,
`BaCl_(2)` is more effective in causing coagulation
`Ba^(2+)gt K^(+)`
