1. Predict the solubility of each of the following compounds at 25°C. Then determine which of the two compounds in each case is more soluble. Afterward, decide whether you could have determined which of the two compounds was more soluble just by comparing the Ksp values. Explain why or why not. All Ksp values are given at 25°C. a. Magnesium fluoride, MgF2, a compound used to produce lenses in telescopes and other optical devices,...
