Question Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g) a)What volume of 1.00 M HCl in liters is needed to react completely (with nothing left over) with 0.250 L of 0.400 M Na2CO3? b)A 565-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 14.1 g CO2. What was the concentration of the HCl solution?

Question

Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and

carbon dioxide (CO2). This equation is balanced as written:

2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g)

a)What volume of 1.00 M HCl in liters is needed to react completely (with nothing left over) with 0.250 L of 0.400 M Na2CO3?

b)A 565-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 14.1 g CO2. What was the concentration of the HCl solution?
