A lake has been acidified to a pH of 4.525. If the lake has a volume of 2.97x104 cubic meters, what mass, in kg, of CaO must be added to raise the pH to a value of 7.00? Hint: The reaction of CaO with water is: CaO + H2O– Ca(OH)2 kg CaO
A lake has been acidified to a pH of 4.210. If the lake has a volume of 5.32×104 cubic meters, what mass, in kg, of CaO must be added to raise the pH to a value of 7.00? Hint: The reaction of CaO with water is: CaO + H2O Ca(OH)2
Lake that have been acidified by acid rain, a combination of nitric and sulfuric acid, can be neutralized by a process called liming, in which limestone (the basic calcium carbonate) is added to the water. What mass of limestone (in kg) would be required to completely neutralize a 5.8x106 m3 lake that contains 1.9x10-5 M H2SO4 and 8.8x10-6 M HNO3?

Hagg lake has a volume of 66,160,000 m^2 and has a pH of 7.4 and assume the lake is pure water with a pH of 7,000 If you were to dump 3,500 pounds of Na metal into the lake what would the pH be at equilibrium. 1,000 lb = 453.6 g and remember that 1 mL = 1cm^3
1. Lakes that have been acidified by acid rain can be neutralized by liming, the addition of limestone (CaCO3). How much limestone in kilograms is required to completely neutralize a 5.8×109 L lake with a pH of 5.7? Express your answer using one significant figure. 2. For each strong base solution, determine [OH−], [H3O+], pH, and pOH. 0.0412 M Ba(OH)2 3.9×10−4 M KOH 2.5×10−4 M Ca(OH)2
Iron has a mass of 7.87 g per cubic centimeter of volume, and the mass of an iron atom is 9.27 × 10-26 kg.
