A 100.0 mL sample of 0.180 mol L^-1 HClO₄ is titrated with 0.270 mol L^-1 NaOH. Determine the pH of the solution after the addition of 75.0 mL of NaOH. A) 12.1 B) 2.65 C) 11.35 D) 1.89 E) 13.06

Question

Quizplus · Accepted Answer

The correct answer is A because the pH of the solution after the addition of 75.0 mL of NaOH is 12.1. This is because the reaction between HClO4 and NaOH is a neutralization reaction, which results in the formation of water and a salt. The pH of the solution will be greater than 7, which indicates that the solution is basic.
