Question

In the reaction H2CO3 (aq) + 2NH3 (aq) = 2NH4^+ (aq) + CO3 2- (aq), how many electrons are transferred?

A. 1

B. 2

C. 3

D. 4

E. None Of The Above (This Is Not A Redox Reaction)

Answer 1

The electrons are transferred when the reaction is redox reaction. It means that there must be reduction and oxidation.

The given equation is

`H_(2)CO_(3) (aq)+2NH_(3) (aq)=2NH_(4)^(+)(aq)+CO_(3)^(-2)(aq)`

The oxidation number of each element remains the same before and after the reaction.

H = +1

C: +4

O: -2

N: -3

Thus this is simple acid base reaction and not redox

There is transfer of proton from bicarbonate to ammonia

this is not a redox reaction
