Q. 4.1
Predict what will happen when the following pairs of dilute aqueous solutions are mixed.
(a) Cu(NO_{3})_{2} and (NH_{4})_{2}SO_{4} (b) FeCl_{3} and AgNO_{3}
STRATEGY
1. Follow the schematic diagram in Figure 4.3.
2. Use the precipitation diagram (Figure 4.2) to determine whether or not the possible precipitates are soluble.
Step-by-Step
Verified Solution
| Cu^{2+} and NO^{-}_{3} from Cu(NO_{3})_{2}; NH^{+}_{4} and SO^{2-}_{4} from (NH_{4})_{2}SO_{4}
CuSO_{4} and NH_{4}NO_{3} Both are soluble, no precipitate forms |
(a) Ions in solution Possible precipitates Solubility |
| Fe^{3+} and Cl^{-} from FeCl_{3}; Ag^{+} and NO^{-}_{3} from AgNO_{3}
AgCl and Fe(NO3)_{3} Fe(NO_{3})_{3} is soluble, AgCl is insoluble. AgCl precipitates. |
(b) Ions in solution Possible precipitates Solubility |
