What will be the coefficients of water and proton, if the following equation is balaned in acidic medium `Cl_(2) + HC_(2)O_(4)^(-) rarr 2Cl^(-)+ 2CO_(3)^(2-)`

Explanation

Balancing the given equation with respect to number of electrons
`Cl_(2) + HC_(2)O_(4)^(-) rarr 2Cl^(-) + 2CO_(3)^(2-)`
Balancing oxygen atom by water and proton
`Cl_(2) + HC_(2)O_(4)^(-) + 2H_(2)O rarr 2Cl^(-) + 2CO_(3)^(2-) + 5H^(+)`
Hence the coefficients of water and proton are 2 and 5 respectively
