3. In ionic equations, mass and charge must be balanced on both sides to form a
proper reaction. Why is this the case? If you have a combination of solutions that
forms a precipitate, what factor determines the amount of precipitate that will
form? (Hint: If you have more of one ion than another as the precipitate is
forming, what will happen?)

4. What criteria did you use to determine which compound was responsible for
Qorming the precipitate? For example, in the combination of nickel nitrate (Ni(NO3)2)
and potassium hydroxide (KOH), how do you know if the precipitate is the combination of nickel and the nitrate ion, nickel and the potassium ion, nickel and
the hydroxide ion, and so on?
