Question

The coagulation power of electrolyte ' $X$ ' is ___ times greater than that of electrolyte ' $Y$ '. The coagulation values of $X$ and $Y$ are $30$ and $138$ respectively.

Answer 1

Answer: 4.6

Coagulation power is inversely proportional to the coagulation value. Therefore, the ratio of coagulation power is:
$\frac{\text{ Coagulation power of }X}{\text{ Coagulation power of }Y}=\frac{\text{ Coagulation value of }Y}{\text{ Coagulation value of }X}$
$=\frac{138}{30}$
$=4.6$
$\therefore X$ has $4.6$ times greater coagulation power than $Y$.
