The equilibrium concentration of hydroxide ion in a saturated aluminum hydroxide solution is _______M. The KSP of aluminum hydroxide is 1.9 × 10-33. That is all the information given to me.
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...
Calcium hydroxide is a strong base but is not very soluble ( Ksp = 5.02 X 10-6 ). What is the pH of a saturated solution of Ca(OH)2 ?
(6 points) The concentration of calcium in a saturated aqueous solution of calcium carbonate (CaCO3) at 25°C is 6.71x10-SM. What is the Ksp of this sparingly soluble salt? CaCO3(s) = Ca2+(aq) + CO32- (aq) Ksp = (Ca2+)( CO32-)
1) Use equilibrium ion concentration to calculate Ksp. The Pb2+ concentration in a saturated solution of lead bromide is measured and found to be 1.19×10-2 M. Use this information to calculate a Ksp value for lead bromide. Ksp =___________ 2) Use solubility to calculate Ksp. The solubility of Fe(OH)2 is measured and found to be 1.15×10-3 g/L. Use this information to calculate a Ksp value for iron(II) hydroxide. Ksp =______________
