2. Applying fundamental chemistry concepts to potable water treatment. Precipitation of lead hydroxide Pb(OH)2 on the inside wall of water pipes is used to decrease the concentration of dissolved lead (Pb2+) in drinking water. Assume that a water treatment plant adjusts the pH of the finished drinking water before it enters the water distribution system, which contains old lead pipes. Which pH would result in a lower concentration of dissolved lead in drinking water: pH 7 and pH 8? Prove...
