Question 1

Finding the pH from known concentrations of a conjugate acid-base pair (Henderson-Hasselbalch equation)

Answer 1

pH = pKa + log ( [base] / [acid] )

Question 2

Defining the equilibrium condition for a saturated solution of a slightly soluble compound, M_p X_q, composed of M(n+) and X(z-) ions

Answer 2

Q_sp = K_sp = [M(n+)]^p [X(z-)]^q
