Some of the moles of HCl you add will react with sodium carbonate in the first reaction and the rest will react with sodium hydroxide in the second reaction.
1. Na2CO3 (aq) + 2HCl (aq) --> 2NaCl (aq) + CO2 (g) + H2O (l)
2. HCl (aq) + NaOH (aq) --> NaCl (aq) + H2O (l)
If you use 0.502 mol HCl (total) and 0.252 mol NaOH in this experiment, answer the following:
a. How many moles of the HCl react with NaOH?
b. How many moles of the HCl react with Na2CO3?
c. How many moles of NaCO3 react with the HCl?
