Common features in acids and bases CBSE Class 10 Chemistry Notes
There are some common features in both acids and bases they are Acids and Bases conduct electricity in aqueous solution as acids and bases dissociate in solution to produce H+ ions and OH- ions respectively.Take solution of hydrochloric acid. Fix two nails on a cork, and place the cork in a 100 mL beaker. Connect the nails to the two terminals of a 6 volt battery through a bulb and a switch. Now pour some dilute HCl in the beaker and switch on the current.
Similarly take a basic solution and do the same .

In the experimental set up the bulb starts glowing . Which indicates that there is a flow of electric current through the solution. The electric current is carried through the solution by ions. Cations (H+ ions) in acid carry electric current in the solution . so H+ ions are responsible for their acidic properties. Similarly , anions (OH- ions) carry electric current in the solution . so OH- ions are responsible for their basic properties.
