Determine the equivalent masses of the following underline compounds by both oxidation number and electrons methods:
underline`(HNO_(3))+3H^(+)toNO+2H_(2)O`

Text Solution

Verified by Experts

Oxidation number method:
`Hoverset(+5)NO_(3)+3H^(+)tooverset(+2)NO+2H_(2)O`
In this reaction ,the oxidation number of N decrease from +5 to +2 So, the change in oxidation number per molecular of `HNO_(3)` =5=3 unit .
`therefore`Equivalent mass of `HNO_(3)`
`("Molecular mass of "HNO_(3))/(1)=(63)/(3)=21`
Electronic method : `NO_(3)+4H^(+) +3e to NO +2H_(2)O`
The number of electron involves in the reduction of 1 molecule of `HNO_(3)=3`
`therefore` Equivalent mass of `HNO_(3)`
`("Molecular mass "of HNO_(3))/(1)=(63)/(3)=21`
