c) K2CO3
D) Mg(NO3)2
Expert Solution

Step 1
When the chemical reaction between cation and anions of the aqueous solution produces an insoluble ionic solid it is known as precipitate and the reaction is called a precipitation reaction. The rate of precipitate formation depends on temperature, buffers, the concentration of the solution, etc. A precipitation reaction is a displacement reaction where, as a cation or anion, the ions substitute each other based on their charge. The insoluble precipitate is separated using methods like filtration, centrifugation, and decanting.
