From the solubility data given for the following compounds, calculate their solubility product constants. I. BiI3, bismuth iodide, 7.7x 10-3 g/l II. Ag2SO4, silver sulfate, 5.0 mg/ml

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
