Aqueous solution of $0.004 M$ $N a_{2} S O_{4}$ and $0.01 M$ glucose are isotonic. The percentage degree of dissociation of $N a_{2} S O_{4}$ is

Options:

Answer:

Solution:

For two solutions to be isotonic.

$i \times π_{{Na}_{2} {SO}_{4}} = π_{Glucose}$

$(1 + 2 α) C_{1} R T = C_{2} R T$

$(1 + 2 α) \times 0.004 = 0.01$

$α = 0.75$ or $75 %$
