Chlorine is prepared in the laboratory by treating manganese dioxide `(MnO_(2))` with aqueous hydrochloric acid according to the reaction,
`4HCl_((aq))+MnO_(2(s))rarr2H_(2)O_(l)+MnCl_(2(aq))+Cl_(2(g))`
How many gram of `HCl` react with `5.0 g` of manganese water to make `250.0mL` solution.

Text Solution

Verified by Experts

`4HCl_((aq.))+MnO_(2(s))rarr2H_(2)O_(l)+Cl_(2(g))+MnCl_(2(aq.))`
`:' 87 g MnO_(2)` react will `4xx36.5 g HCl`
`:. 5 g MnO_(2)` will react with `=(4xx36.5xx5)/(87)= 8.39 g HCl`
