How many mL of perhydrol is requried to produce sufficient oxygen which can be used to completely convert 2 L of `SO_(2)` gas of `SO_(3)` gas?

Options

A. 10 mL
B. 5 mL
C. 20 mL
D. 30 mL

Answer

A

Explanation

`H_(2)O_(2) to H_(2)O + (1)/(2)O_(2)`
`SO_(2) + (1)/(2)O_(2) to SO_(3)`
`1L " "1//2L" "1L`
`2L " "1L" "2L`
Perhydrol is 30% solution of `H_(2)O_(2)`
Volume of strength of 30% `H_(2)O_(2)` solution is 100 means 1 mL of this solution on decomposition gives 100 mL oxygen
100 mL oxygen is obtained by 1 mL of `H_(2)O_(2)`
`rArr` For 1000 mL of oxygen 10mL of `H_(2)O_(2)` is needed
