Question

$30 \%$ solution of $H _{2} O _{2}$ is marketed as $X$ volume hydrogen peroxide. It means that one millilitre of $30 \% H _{2} O _{2}$ solution will give $Y$ volume of oxygen at STP. Here, $X$ and $Y$ respectively are

• A. $10\, V$ and $100 \,mL$
• B. $100 \,mL$ and $10 \,V$
• C. $100 \,V$ and $100 \,mL$
• D. $10\, V$ and $50 \,mL$

Answer 1

Answer: (C)

$30 \%$ solution of $H _{2} O _{2}$ is marketed as ' $100\, V$ ' hydrogen peroxide. It means that, one millilitre $1 \,mL$ of $30 \% H _{2} O _{2}$ solution will give $100\, mL$ of oxygen at STP.
