Homework Answers
Si ,Al,Fe are insoluble in water >Hence these elements are not abundant in seawater
2)The solid substance formed in the solution when two solutions
are mixed is called
precipitate.
The chemical reaction which produce solid substance [precipitate]
as a product
is called precipitation reaction
4)
balanced molecular equation:
Pb(NO3)2(aq) + 2 NaI(aq) ----> 2NaNO3 (aq) + PbI2 (s)
Net ionic equation:
Pb2+ + 2I-(aq) ----> PbI2(s)
**********************************
| compound | soluble | compound | soluble |
| NaCl | Yes | CaCl2 | Yes |
| AgCl | No | Ca(NO3)2 | Yes |
| AgNO3 | Yes | CaSO4 | yes |
| Ag2SO4 | No | CaCO3 | No |
| Hg2(SO4) | No | Pb3(PO4)2 | No |
All solved :)

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
