The reaction of weakly basic anions with H2O tends to make the actual solubility of many salts higher than predicted. Ksp Lab Experience Dr Fus. When a transparent crystal of calcite is placed over a page, we see two images of the letters. The product of solubilities of the ions with the number of each ion in power is known as the solubility product. In our calculation, we have ignored the reaction of the weakly basic anion with water, which tends to make the actual solubility of many salts greater than the calculated value. When a liquid evaporates in a closed . Explanation: 1) Equilibrium equation: Ca (IO) Ca + 2 IO 2) By stoichimetry ratio, the concentrtion of IO ions is the double than the concentraion of Ca , so call them x and 2x. stream Solution 1: Obtain 0.50 gm of Ca(IO3)2 and transfer it into a 250 ml beaker.
