Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2(s) pb+2(aq) + 2cl-(aq). if a solution has a current value of keq of 1.2 x 10-2, which statement is true? too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

"The solution is unsaturated" is the statement among the following choices given in the question that is true. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope that this is the answer that has actually come to your desired help.

The stoichiometric equation above is given. We make sure that the balancing of the equation is correct by checking all the elements. From the balanced reaction, every mole of MgCl2, there is one mole of Mg(OH)2 produced. Hence, there is a one to one ratio correspondence.
