10 ml of H_(2)O_(2) solution on treatment with Kl and titration of liberated lz required 20 mL of 1 N hypo solution. What is the normality of H_(2)O_(2) solution?

Answer»

Solution :2
`H_(2)O_(2)+2ItoI_(2)`
`I_(2)+2S_(2)O_(3)^(2-)toS_(4)O_(4)^(3-)+2I`
`H_(2)O_(2)=I_(2)=2S_(2)O_(3)^(2-)`
`N_(1)V_(1)=N_(3)V_(2)`
`H_(2)O_(2)`
`N_((N_(1)O_(2))=(20xx1)/(10)=2N`
