Question

A sample of calcium hydroxide is placed into a jar containingwater. The mass of the calcium hydroxide same is 1.34g. Assume the water is at 20 degrees C and that the resultingcalcium hydroxide solution is saturated. What mass of waterwas present in the jar?

Explanation / Answer

Since the solubility of Calsium Hydroxide , S = 0.173 / 100 gof water i.e., 0.173 g of Ca(OH) 2 is dissolved in 100 g of water tomake it saturate So , 1.34 g of Ca(OH)2 is dissolved in x g of water X = ( 100 * 1.34 ) / 0.173     = 774.56 g of water Therefore the mass of water was present in the jar is 774.56g
