If 50 cm³ of 0.1 M HCl is mixed with 50 cm³ of 0.1 M NaOH at 25°C, what is the pH of the final mixture?
Q1. If 50 cm³ of 0.1 M HCl is mixed with 50 cm³ of 0.1 M NaOH at 25°C, what is the pH of the final mixture?
Answer: pH = 7
Explanation: Mixing equal volumes of a strong acid and strong base of the same molarity results in complete neutralization, forming a neutral solution (pH 7).
