$\text{5}\text{ml}$ of $A{s}_{2}{S}_{3}$ is mixed with distilled waterand $\text{0}\text{.01}\text{M}$ solution of an electrolyte $\text{AB}$ so that total volume is $\text{10}\text{ml}$. it was found that all solution containing more than $\text{5}\text{ml}$ of $\text{AB}$ coagulate within $\text{5 min}$. What is the Flocculation value of $\text{AB}$ for $A{s}_{2}{S}_{3}$ sol?
