Make sure that quations are all e balanced, and all phase designations are indicated. This precipitation reaction is described by the following equation: 2 Na 3 PO 4 (aq) + 3 CaCl 2 (aq) --> 6 NaCl (aq) + Ca 3 (PO 4) 2 (s). KHP is an acidic substance, with the ionizing hydrogen being set forward in the formula for emphasis. 25 moles of sodium hydroxide in every liter of solution. Whereas the Cu 2+ and CO 32− ions combine to form a precipitate of solid CuCO 3.
