A bottle labeled with "`12V" "H_(2)O_(2)`" contain 700 ml solution. If a sdudent mix 300 ml water in it what is the g/litre strenth & normality and volume strength final solution.

Explanation

`N=12/5.6`
meq. of `H_(2)O_(2)=12/5.6 times 700`
let the normality of `H_(2)O_(2)` on dilution is N
meq. before dilution = meq. after dilution
`N times 1000=12/5.6 times 700N=12/5.6 times 7/10=1.5`
`M=1.5/2`
strength gm/lit `=1.5/2 times 34=25.5`
volume strength `=N times 5.6=84/10=8.4V`
