Consider the following saturated solution of calcium hydroxide. Ca(OH)2 (s) + Ca(aq) + 2OH(aq)
What effects, if any, will adding Cl have on the position of equilibrium?
A) shifts to product side
B) shifts to reactant side
C) will increase the concentration of Ca(OH)2 (8)
D) None

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
