Hco2h + H2o --->

M.A.H

Hi I need help on this equation:

HCO2H + H2O --->

The question askes to complete and balance the eqaution and showing the ions that form when HCO2H dissolves in water.

I think the eqaution is:

HCO2H + H2O ---> OH- + H+ + HCO2-

am i right or wrong?

I think its ... H3O+ + HCO2-

lets see what the experts say...

What is HCO2H? That's not desparately clear. I reckon it's methanoic acid,

I'm pretty certain you're both wrong, as carboxylic acids don't fully dissociate in water(equilibrium).
methanoic acid + h2o (equilibrium arrow) h3o+ + HCO2-
Although, we learnt about that olny in the equilalent of A level, so if you're doing anything below that I reckon you could say H+ instead of H3o+

Yes its HC02H + H20 ----> H30+ + HCO2-

technically it *is* an equilibrium reaction but yeah...

In the equation that you have originally written, the charges dont balance and there is one more H atom on the left hand side.

Fisherman - Im pretty sure theyre arnt any other common compounds with the formula HC02H, if any at all. You're right about the H+ thing, but since H20 is in the equation on the LHS, it wouldn't balance with just H+.
