NaHCO3 + HCl ->

and

KHCO3 + HCl ->

:confused:

I'll do the first one for you. Then do the second one to see if you understood, OK?

NaHCO3 + HCl -> NaCl + H2O + CO2

Notice that when an acid is added to a metal carbonate (but here it is a hydrogen carbonate, but the reaction is nearly the same), carbon dioxide is gien off, and a salt is produced. The salt is NaCl, and CO2 is the carbo dioxide. The substances left are O and 2 H. They will combine to form water. Now, try to do the second one on your own.

Hum, could you do it? I mean the second one,

KHCO3 + HCl ->

KHCO3 + HCl --> KCl + H2O + CO2
