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...
if the ph of of Cu(OH)2 is a certain number would the solubility increase decrease or no change
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.

Part a please Question 3 (30 pts) Lead nitrate (Pb(NO3)2) is a toxic compound used in lead paints in the past. It has far less use now, in specialized applications such as gold extraction. Unlike most lead salts, lead nitrate is soluble in water, as seen below in the solubility chart. After aqueous gold recovery, it is desired to recover the lead nitrate from the water via crystallization. A 70°C aqueous lead nitrate solution containing 50 wt% lead nitrate and...
What is the solubility of PbSO4 in a solution which originally was 0.050 M in Pb(NO3)2?
Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
The molality of lead nitrate in 0.726 M Pb(NO3)2 is: (The density of the solution is 1.202 g/ml)
