Give reason for the following(a) Dry HCI does not change the colourof dry litmus paper.(b) Aqueous solution of an acid conductselectricity |
|
Answer» Dry HCl does not change the colour of litmus paper because water is required for the formation of hydronium ions which is responsible for the colour change of litmus paper. Since there is no water in this case, the formation of hydronium ions won't take place and no colour change would be observed. Aqueous solution of an acid conducts electricity because it contains H+ ions. |
