Barium hydroxide is slightly soluble in water,with a K_sp of 5.00 × 10^-4 at 298K.The dissolution of barium hydroxide in water is an endothermic process. Ba⁺²(aq)+ 2OH^-(aq) Which of the following will increase the solubility? A)Barium hydroxide is added to the solution. B)Sodium hydroxide (NaOH)is added to the solution. C)The temperature is decreased. D)HCl is added to the mixture.(HCl reacts with OH-,removing it from the system. )

Question

Quizplus · Accepted Answer

Adding HCl to the mixture will remove OH- ions from the system due to the reaction between HCl and OH-, which shifts the equilibrium towards more dissolution of barium hydroxide to replace the removed OH- ions, thus increasing its solubility.
