1. Which of the following double replacement reactions would actually occur? Using your solubility chart, circle the ones that would and explain how you
identified each of them.
a. 3Ca(OH)2 + 2H3PO4 = Caz(PO.)2 + 6H2O
b. K, Co, + BaCl2KCl +Baco,
I
C. AICI: + 3LINO, = AI(NO3)3 + 3LICI
d. Cuso. + 2KBr - CuBr2 + K, SO
e. Mg(OH)2 + 2HCI = MgCl2 + 2H,0

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
