Question

35.00 ml of a 0.30 m hcl solution is titrated with 0.35 m naoh. what is the ph of the solution after 40.00 ml of the naoh has been added?

Answer 1

The pH of the solution after adding NaOH to HCl will be 7, indicating a neutral solution.

Step-by-step explanation:

To calculate the pH of the solution after 40.00 mL of 0.35 M NaOH has been added to 35.00 mL of a 0.30 M HCl solution, we need to consider the reaction between NaOH and HCl. This is a neutralization reaction in which NaOH reacts with HCl to form NaCl and water:

NaOH + HCl → NaCl + H2O

Since NaOH is a strong base and HCl is a strong acid, the NaCl formed in the reaction will dissociate completely, resulting in a neutral solution.

Therefore, the pH of the solution after the addition of NaOH will be 7, which indicates a neutral solution.
