Precipitation of lead hydroxide Pb(OH)2on 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 your answer with calculations. The solubility product constant (Ksp) for...
. Given the reaction Mn2+ + 2OH- = Mn(OH)2 (s), calculate the pH required to decrease the manganese concentration (in the form of Mn2+) in a water supply to 0.03 mg/L. Note that the solubility product Ksp = 8×10-14.
2. What is the PCO2 and CO3 (aq) concentration of a 5 °C ground water sample with pH= 6.5, and 50 mg L HCO; (aq)? 3. In 1960 the average concentration of CO2(g) is 316.91 ppm. What was the pH of acid rain then. 4. Henry's constant for CO2(g) decreases with temperature, and therefore the solubility of CO2(g) also decreases with temperature. Use enthalpy data at 25 °C and Le Chatelier's principle to explain why and how equilibrium shifts with...
