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) โ 2NaCl(aq) + H2O(l) + CO2(g)
1) What volume of 1.50 M HCl in liters is needed to react completely (with nothing left over) with 0.500 L of 0.200 M Na2CO3? Express your answer numerically in liters.
2) A 581-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 15.1 g CO2. What was the concentration of the HCl solution? Express the molar concentration numerically.
