7(iii)
From the list given, choose the method which is most suitable for the preparation of the following salts?
- E - Neutralization by titration
- F - Precipitation
- G - Simple displacement
- H - Direct combination
(a) Zinc sulphate
(b) Silver chloride
(c) Ammonium nitrate
Show SolutionHide Solution↓
(a) Zinc sulphate — G: Simple displacement (zinc, being above hydrogen, displaces hydrogen from dilute sulphuric acid).
(b) Silver chloride — F: Precipitation (silver chloride is an insoluble salt).
(c) Ammonium nitrate — E: Neutralization by titration (a soluble salt of the alkali ammonium hydroxide with nitric acid).
