Conductance of Electrolytic Solutions
The equivalent conductivity of a solution containing 2.54g of CuSO4 per litre is 91.0 W-1 cm2 eq-1. Its conductivity would be
1.45 x 10-3W-1cm-1
2.17 x 10-3W-1cm-1
2.90 x 10-3W-1cm-1
2.9 x 10-3W-1cm-1
Consider the statements about electric conductivity.
i)Copper metal:Flow of electric current happens by the electron flow.
ii)Copper sulphate solution:Flow of electric current happens by the electrons, molecules and ions.
- Only i) is correct
- Only ii) is correct
- Both i) and ii) are correct
- Both i) and ii) are incorrect
The conductance in electrolytic solutions is due to flow of ions which are produced by the decomposition of matter.
During electrolysis of an electrolyte, the number of ions produced is independent of the _______ .
- Nature of solvent
- Nature of the electrolyte
- All of the above
Which of the following is true?
Distilled water conducts electricity
Salt solution does not conduct electricity
Dilute hydrochloric acid does not conduct electricity
Dilute hydrochloric acid conducts electricity
- ∧mHCl> ∧mKCl > ∧mNaCl >∧mLiCl
- ∧mLiCl> ∧mNaCl > ∧mKCl >∧mHCl
- ∧mLiCl> ∧mNaCl > ∧mHCl >∧mKCl
It has been observed that gaseous hydrogen chloride is a very poor conductor of electricity but a solution of hydrogen chloride gas in water is a good conductor of electricity. This is due to the fact that
- Hydrogen chloride gas in water solution ionizes
- A gas is non-conductor but a liquid conducts electricity
- Gas does not obey Ohm's law whereas solution does
- Water is good conductor of electricity
