14 and 15 please!!

14. Given the reactions: YF3(a)Y3+(aq)+3F(aq)H+(aq)+F(aq)=HF(aq)K50=8.621021Ka=6.3104 a. Write the overall reaction for the dissolution of YF3 in a HF solution (1 point) b. Predict how the solubility of Y3 changes in terms of Q and K as i. pH of the solution decreases (1 point) ii. pH of the solution increases (1 point) Free Energy of Dissolution 15. Two ionic solids are placed into 1.00L of distilled water. Draw a particle diagram that could represent the two solutions with some solid at the bottom of each container. (5 points)
