Given the solubility of calcium hydroxide is 0.0000064 at 25 degree celcius.calculate its solubility at this temperature in
I) water
II) 0.1M calcium chloride solution
0.0000064 WHAT????
According to my sources Ksp is 5.5E-6 so I wonder if this is Ksp and not solubility. My sources show solubility in water as almost 2 g/L
