Conduction of Electricity in Water
A sugar solution is a better conductor of electricity when compared to a salt solution.
What makes tap water a fairly good conductor of electricity?
None of these
Its property of being a universal solvent
- Common salt
Hydrogen gas will be formed at the electrode which is connected to the positive terminal of the battery
Hydrogen gas will be formed at the electrode which is connected to the negative terminal of the battery
No gas is formed at any electrode
Oxygen bubbles will be formed at the electrode which is connected to the negative terminal of the battery
There is a sample of water. However it is unknown if the sample is that of pure distilled water or it contains salts and other impurities. Can you determine if it will conduct electricity or not with just the given information?
- Depends on temperature of water
Can't be said
Why is it advised to cut off power supply and switch off all electrical appliances at the time of a flood?
Because water is a good conductor of electricity.
Because water is a poor conductor of electricity.
Because it is important to save electricity.
None of these.
- Water has free electrons.
- Water provides extra insulation.
- Water increases conduction.
- Water decreases conduction.
- Chlorine and nitrogen
- Hydrogen and oxygen
- Oxygen and chlorine
- Hydrogen and chlorine
- Tap water has extra electrons.
- Impurities in tap water has ions.
- Tap water has static electricity.
- Tap water has a conductor in it.
