Question

Zinc chloride is soluble.

Give the name of a soluble carbonate.
Give the name and formula of the precipitate formed when zinc chloride reacts with the
carbonate in a.

4 a Give the names of two solutions that would react together to form a precipitate of lead
chloride.
b Give the name and formula of the soluble product of this reaction.
Write the word equation for this reaction.

5 Copy and balance the following equations and add state symbols. Then write a word equation for
each.
a NaOH + CuCl2-NaCl + Cu(OH)2
b Ca(NO3)2 + Na2CO3 - CaCO3 + NaNO3
(NH4)2SO4 + Pb(NO3)
2NH4NO3 + PbSO4

Answer 1

Sodium Carbonate is Soluble

-

Lead Iodide and Sodium Chloride

PbCl2 + NaI

Lead Iodide + Sodium Chloride —> Lead Chloride + Sodium Iodide


2NaOH + CuCl2 —> 2NaCl + Cu(OH)2
Sodium Hydroxide + Copper Chloride —> Sodium Chloride + Copper Hydroxide

Ca(NO3)2 + Na2CO3 —> CaCO3 + 2NaNO3
Copper Nitrate + Sodium Carbonate—> Calcium Carbonate + Sodium Nitrate

(NH4)2SO4 + Pb(NO3)2 —-> 2NH4NO3 + PbSO4
