Electric effects of electric current
Chemical effects
Passage of an electric current through a conducting solution
causes a chemical reactions
Examples
Passing current through solution
Deposits of metal of electrodes connected to negative terminal of battery
Change of color of solution
Bubble of gas on electrodes
Liquids
Types of solution
Acid
Salt Solution
Base
Some liquids are poor conductors
Distilled water ( no dissolved water) [ Absolutely pure]
different than rain water
Rain water collects minerals from atmosphere
Some liquids are good conductors
Water containing salt solution
Electroplating
Example
Zinc
Expensive
Does not corrode
Iron
Strong
Cheap
Corrodes
