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)
What volume of 1.25 M HCl in liters is needed to react completely (with nothing left over) with 0.750 L of 0.400 M Na2 CO3?
