6. Calculate the pH of a buffer that contains 0.125 M cyanic acid, HCNO (K, = 3.5 x 10-), with 0.220 M potassium cyanate, KCNO. Hint: • • Use the Henderson-Hasselbach equation. KCNO (aq) dissociates into K and CNO; CNO and HCNO are conjugate acid base pairs because they differ by an H". 7. Calculate the solubility of Li,PO4 in pure water in grams/L. The solubility product, Kip, of LisPO4 in water at 25°C is 2.37 x 10. Hint: First change solubility to molar solubility (Units for molar solubility are moles/L)
