    (a) If an acid is added to a base then salt and water are formed.
     
    (b) Dry HCl gas does not change the colour of dry litmus paper because dry HCl gas has no hydrogen ions (H+ ions) in it which can impart acidic properties to it.
     
    (c) Phenolphthalein indicator turns pink when added to an alkali.
