7. Calcium sulfate (solid) is added to a solution of water to achieve a concentration of...
Consider a body of water in equilibrium with solid calcium sulfate, CaSO4. The Ksp for calcium sulfate is 3.0 x10-5. Calculate the solubility, in moles per Liter of calcium sulfate in water assuming that other reactions are negligible. Enter you value in non scientific notation (e.g., 0.0011).
A chemist prepares a solution of calcium sulfate (Caso.) by measuring out 0.221% of calcium sulfate into a 400 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's calcium sulfate solution. Round your answer to 3 significant digits. moll.
7. The ancient Romans added calcium sulfate to wine to clarify it and to remove dissolved lead. What is the maximum [Pb2+] that might be present in wine which is saturated with calcium sulfate?

5.0 g of solid Al(NO3)3 was added to enough water to make a 100.0 mL solution. Al(NO3)3 is very soluble in water. 1. Write out the dissolution reaction that occurs when the solid Al(NO3)3 was added to water. 2. What is the concentration, in Molarity, of Al(NO3)3 once it is dissolved in the water? 3. If 53 mL of water was added to the original Al(NO3)3 solution described above, what is the new concentration in Molarity? 4. What is the...
The mass of calcium hydroxide that is dissolved in 175 mL of a saturated solution is grams. The volume of water needed to dissolve 0.0522 grams of silver sulfate is L. Assume no volume change upon addition of the solid.
a tank with 500 liters of water initially contains 4g of calcium. Water with a concentration of 3 mg/L is pumped into the tank at a rate of 1L/min and the mixture is pumped out at the same rate. (a) Write a differential equation and its initial condition for, y(t), the total amount of calcium in grams in the tank. (t is measured in minutes, 1g = 1000mg) (b) Find the general solution to this differential equation. (c) Find the...
