Determine the pH of a solution prepared by mixing the following:
25) 0 mL of 0.200 M HCl
75) 0 mL of 0.100 M NaOH
50) 0 mL of 0.200 M NaH₂PO₄For H₃PO₄ K_a1 = 7.5 × 10^-3, K_a2 = 6.2 × 10^-8, and K_a3 = 4.8 × 10^-13.

Question

Quizplus · Accepted Answer

The correct pH of the solution is 6.73. This is determined by first calculating the moles of each reactant, then determining the reaction outcomes and finally calculating the pH based on the remaining species and their concentrations. The given acids and base will react to neutralize each other, and the pH will be influenced by the remaining species and their dissociation constants. The complex nature of the polyprotic acid (NaHS) and its dissociation constants also play a crucial role in determining the final pH.
