Question
Individual effort: Consider a hypothetical solution that is [Ba(OH)2 = 0.036 M. Barium hydroxide unlike calcium hydroxide, is soluble in water at room temperature. 1. (5 pt) Write a dissociation equation, like the one shown for calcium hydroxide in the lab procedures to show solid barium hydroxide dissolving into its aqueous ions. Since it is soluble, t is not an equilibrium expression. 2. (5 pts) Calculate the concentrations of each of the following ions in the solution. [Ba^2] = [OH^-] = 3. (5 pts) Complete the following chemical equation: Ba(OH)2 (aq) + HCI (aq) 4. (5 pts) Write the net ionic equation for the reaction above.Explanation / Answer
1)
Ba(OH)2 ---> Ba+2+ 2
