    Using stock bottles of CaCl2 and KOH solutions, a student prepared a 1.00L solution mixture which contained, before any reaction occurred, [Ca2+] = 0.075M and [OH–] = 0.085M. After mixing the solution, a precipitate of Ca(OH)2 (s) was formed (reaction occurred in the right-to-left direction). The student then added a further 1.00L of water and stirred; the precipitate disappeared— all the solid had redissolved. Which one of the following is a possible value for the equilibrium constant, Kc, of this...
