If CO2 is not removed by boiling the solution after the addition of HCl, how will this affect the amount of NaOH required to reach the titration endpoint

Answer:

See explanation

Explanation:

CO2 reacts with water to form carbonic acid as follows;

CO2(g) + H2O(l) ---------> H2CO3(aq)

This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.

Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.
