Follow the directions for Question 9 for the following pairs of solutions.
(a) sodium phosphate and barium chloride
(b) zinc sulfate and potassium hydroxide
(c) ammonium sulfate and sodium chloride
(d) cobalt(III) nitrate and sodium phosphate
(a)
Interpretation:
The net ionic equation should be written when sodium phosphate and barium chloride are mixed.
Concept introduction:
Solubility of any compound is predicted by below solubility chart:
Group-1 cations and |
||||||
Group-2 cations | - | - | ||||
Transitions metal cations |
- | - | - |
Blank boxes indicate no precipitate formation occurs which means soluble in dilute solution.
Boxes with hyphen will form precipitate from dilute solutions and boxes where formula is written this is a cation-anion combination that will form precipitate.
Precipitation reactions: It is a type of chemical reactions where two soluble salts react with each other and formed different products, out of which one product must be insoluble in solution which is known as precipitate.
A chemical equation which shows only the species that are participated in the reaction is said to be net ionic equation.
