ALT CHEM 125 Name Determining the Ksp of Calcium Hydroxide Calcium hydroxide is an ionie solid that is sparingly soluble in water. A saturated, aqueous, solution of Ca(OH), is represented in equation form as shown below. Ca(OH)2 (5) --- Ca' (aq) + 2OH(aq) The solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and its dissolved ions in an aqueous system. The equilibrium expression for calcium hydroxide is shown below. Kp - [Ca][OHT...

A student measures the pH of a saturated solution of manganese(II) hydroxide (Mn(OH)2) to be 9.87 . Part A Based on this measurement, what is the Ksp of Mn(OH)2? Express your answer using two significant figures.
6 6. Zinc hydroxide, Zn(OH)2. is practically insoluble in pure water. (Kap 3.0 x 10-16) a) Determine the pH of a saturated aqueous solution of Zn(O1H)2. (You should assume that all hydroxide ions in the solution come from the Zn(OH)2: you can ignore the autoionization of water.) (4 pts) b) Zn(OH)2 is less soluble in even very dilute solutions of Zn(NOs)2 due to the common ion effect. Determine the molar solubility of zine hydroxide in a 1.0 x 10-4 M...
Mg(OH)2 has a Ksp=5.61x10-12. Determine the pH of a saturated solution of Mg(OH)2. (Magnesium hydroxide is a solid.) (10 points)
3. Consider a room temperature, 100mL aqueous solution saturated with the ionic compound beryllium hydroxide Be(OH)2 due to the addition of 10g of Be(OH)2; MM-43.02 g-mol-1. KsP-2.0 x10-8 Use this provided information to calculate the pH of this saturated solution. Hints: Due to the low solubility product, very little of this compound actually dissolves in H20. Go ahead and assume all activity coefficients are equal to 1.0 for this problem. This seems like a good opportunity to apply the ICE...
