Question

98 g $H_{2}S{O}_4$ is added in water no. of moles of ions produced will be?

• A. $0.3N_a$
• B. $0.3\times 6.023\times {10}^{23}$
• C. $0.3\times 98$
• D. $0.3$

Answer 1

The correct option is B $0.3\times 6.023\times {10}^{23}$

$H_{2}S{O}_4⟶2H^{+}+S{O}_4^{2-}$ ($3$ ions)

$\therefore$ The answer is $0.3\times 6.023\times {10}^{23}$ .
