HCl and Na2CO3 undergo a neutralization reaction. To neutralize the acid and base, 0.0144L of 3.2913M HCl is required, and 0.0251 of 0.9435M Na2CO3 is required. To make sure the volumes of HCl and Na2CO3 neutralize the reaction properly, calculate the pH of the solution to see if the solution is fully neutralized (pH of 7 or close to 7).
