Question

3. It is possible to perform a similar reaction to the one you did in this experiment using sodium carbonate (Na2CO3) instead of sodium bicarbonate (NaHCO3). Balance the following equation for the reaction of Na2CO3 with HCl.

__Na2CO3 + __HCl --> __NaCl + __H2O + __CO2

What mole ratio of NaCl to Na2CO3 does the above balanced equation predict? ____________

Answer 1

Na2CO3 + 2 HCl --> __2 NaCl + H2O + CO2

ratio of 2 mole NaCl to every 1 mole of Na2CO3
