Calculate the strength of 5 volumes `H_2O_2` solution.

Text Solution

Verified by Experts

According to definition, 5 volumes `H_2O` solution means that 1 L of 5 volume `H_2O_2` solution on decomposition produces 5 L of `O_2` at STP
Reaction : `2H_2O_2 to 2H_2O+ O_2`
`2xx34`gm `to` 22.7 L volume of STP
Now,
22.7 L `O_2` at STP will be obtained `H_2O_2`= 68 g
`therefore` 5L of `O_2` at STP will be obtained from `H_2O_2` = ?
`therefore (5xx68)/22.7` gm = 14.98 gm `approx` 15 gm
