1.	What will you observe when: (i) Red litmus is introduced into a solution of sodium sulphate. (ii) Methyl orange is added to dil HCl. (iii) Blue litmus is introduced into a solution of ferric chloride
Answer» (i) Solution of Na₂SO₄ is neutral, therefore, no colour change will be observed when red litmus paper is introduced in thus solution. (ii)The orange colour of methyl orange changes to red in dil. HCl (iii)The colourless solution changes to pink when a drop phenolpthalein is added to solution of lime water. (iv) Solution of ferric chloride is acidic; therefore, blue litmus will change to red in this solution.
