The cations are reduced at the cathode and anions are oxidized at the anode.įor instance, acidified or salt-containing water can be decomposed by passing electric current to their original components hydrogen and oxygen. ElectrolysisĮlectrolysis is known as a process of breaking down ionic mixtures into their components by passing a direct electric current through the compound in a liquid state. If the water is conducting then the bulb will glow, Because we know that all water is not conducting for checking the conductivity of water we dip two ends of the wire in liquid and connect to the battery if the bulb glows then water is conducting. If you place a battery with a negative pole and a positive pole into the water, the negative particles will be drawn to the positive pole and the positive ions will be drawn to the negative pole in this way making a close circuit. Salt, or sodium chloride (NaCl), separates into positive Na ions and negative Cl ions. At the point when salts are broken down in the water, they separate into various electrically charged particles called ions. Any impurities, similar to salts, in the water, tend to conduct electricity. Pure water is a bad conductor of electricity. The greater the number of ions, the higher the conductivity of electricity. An electric current flows via these ions.
When electricity is transmitted through water that has been combined with various compounds, the contents separate into negative and positive ions. The response would be affected by the solution and electrodes employed. Metal deposits on electrodes are possible.
As a result, gas bubbles may form on the electrodes. What happens when a current is passed through a conducting solution?Įlectric current passing through a conductive fluid causes chemical reactions.
