Answer 1

Question 5.

The no. of moles of HCl = 2 mol/L * (250/1000) L = 0.5 mol

The no. of moles of NaOH = 0.5 mol/L * (150/1000) L = 0.075 mol

The resulting no. of moles of HCl after getting neutralized with NaOH = 0.5 - 0.075 = 0.425 mol

The total volume of the resulting solution = 250 mL + 150 mL = 400 mL = 0.4 L

Therefore, the [H⁺] of the resulting solution = 0.425 mol/0.4 L = 1.0625 M

Hence, pH = -Log[H⁺] = -Log(1.0625) = -0.026
