Question

Show difference between acids and alkalis using experiment using litmus

Answer 1

If we take red litmus paper and dip it in an acid, then the colour of the litmus paper remains unchanged whereas if we dip red litmus paper in an alkali,then the colour of litmus paper will turn blue from red.

If we now take a blue litmus paper and dip it in an acid,then the colour of blue litmus paper will turn red whereas it's colour will remain unchanged in an alkali.
