Write the mass balance for a saturated solution of the slightly soluble salt Ag3PO4, which produce PO43- and 3Ag+ when it dissolves. 3. What is the pH of 1.0 10-8 mol/L KOH? (pH = 7.02) 4. 阅读下列文献 From Harris DC Sixth Ed. 完成下列习题： Calculate the pH of each of the following solution: (a) Water in equilibrium with CO2 of the air; pKa1 = 6.38, pKa2 = 10.25. (b) Water as in part (a) brought to pH = 7.00 with NaOH and allowed to regain equilibrium with CO2. C 阅读分析化学文献“Measuring pH inside single cells”From Harris DC Sixth Ed.
