The addition of sodium chloride has reduced the molar solubility of silver chloride, which is still equal to [Ag +] but no longer equal to [Cl-], by two orders of magnitude. A common ion effect is observed whenever any constituent ion is added to a s

sp and the Common Ion Effect Objectives To determine the solubility product constant of ... we will measure the solubility of this salt in pure water and in a solution containing KCl. We will also determine the effect a common ion has on a K sp value

Solubility of KHT and Common ion Effect v010714 ... The solubility product constant is the numerical value that explains the entries in the table. The larger the K sp value the greater the degree of dissociation of the ionic compound in water. The K
