CHXII05:SURFACE CHEMISTRY
320867
Equal volume of each of two sols of AgI, one obtained by adding \(\mathrm{AgNO}_{3}\) to slight excess of \(\mathrm{KI}\) and another obtained by adding \(\mathrm{KI}\) to slight excess of \(\mathrm{AgNO}_{3}\), are mixed together. Then
1 The two sols will stabilise each other
2 The sol particles will acquire more electric charge
3 The sols will coagulate each other mutually
4 A true solution will be obtained
Explanation:
In first case, AgI possess negative charge and in second case, AgI possess positive charge. The mixing of two sols leads to the formation precipitation known as mutual coagulation.
