प्रश्न
How will you find out which of the water soluble compound A or B is ionic?
उत्तर
The test to find out which water soluble compound, A or B, is ionic can be done by the electrical conductivity test. The compound solution that conducts electricity must be ionic in nature and the other compound solution that does not conduct electricity must be covalent in nature.
