Calculate the pH of the resultant mixtures: a) 10 mL of 0.2M Ca(OH)2_2 + 25 mL of 0.1M HCl b) 10 mL of 0.01M H2_2SO4_4 + 10 mL of 0.01M Ca(OH)2_2 c) 10 mL of 0.1M H2_2SO4_4 + 10 mL of 0.1M KOH

(a)
Answer

12.63

(b)
Answer

7

(c)
Answer

1.30

Explanation

To find the pH of the resultant mixtures, we first determine the millimoles of H+H^+ and OH−OH^- ions from the given acids and bases. The ions neutralize each other, and the pH is calculated based on the concentration of the remaining H+H^+ or OH−OH^- ions in the total volume of the mixture.
