Consider the addition of 22.59 mL of 0.1643 M aqueous HCl to 19.01 mL of 0.1558 M aqueous NaOH at 25°C. Assuming the volumes are additive, what is pOH of the resulting solution?

Consider the addition of 18.45 mL of 0.2289 M aqueous HCl to 30.49 mL of 0.2875 M aqueous NaOH at 25°C. Assuming the volumes are additive, what is the molarity of the OH- ions in the resulting solution?

Consider the addition of 19.96 mL of 0.1672 M aqueous HCl to 20.59 mL of 0.3168 M aqueous NaOH at 25°C. Assuming the volumes are additive, what is pH of the resulting solution?

Consider the addition of 36.59 mL of 0.1031 M aqueous HCl to 17.48 mL of 0.1364 M aqueous NaOH at 25°C. Assuming the volumes are additive, what is the molarity of the H+ ions in the resulting solution?
