shown above is the chemical equation for the dissolution of the slightly soluble salt . its value in pure water was experimentally determined. was found to be much less soluble in a solution than in pure water. which of the following correctly explains the decrease in solubility of in ? test booklet 2023 unit 7 ksp page 8 of 9 ap chemistry (a) the concentration of water is much less in the solution than in pure water, reducing the rate of dissolution of the salt. (b) the presence of ions in the solution inhibits the dissolution of salts. (c) the presence of additional already in the solution decreases the value of the for , causing the solubility to decrease. (d) the presence of additional
