Take about 3 mL of sodium sulphatesolution in a test tube. In another test tube, take about 3 mL ofbarium chloride solution. Mix the two solutions (Fig. 1.9). What do you observe?

Describe a chemical test to show that the sodium chloride solution contains chloride ions.

Take about 1g solid NaCl in a clean anddry test tube and set up the apparatus asshown in Fig. 2.4.n Add some concentrated sulphuric acid tothe test tube.n What do you observe? Is there a gas comingout of the delivery tube?

Take about 1g solid NaCl in a clean anddry test tube and set up the apparatus asshown in Fig. 2.4.n Add some concentrated sulphuric acid tothe test tube.n What do you observe? Is there a gas comingout of the delivery tube?n Test the gas evolved successively with dryand wet blue litmus paper.n In which case does the litmus paper changecolour?n On the basis of the above Activity, what doyou infer about the acidic character of:(i) dry HCl gas(ii) HCl solution?
