The effect of of HCl on Blue Litmus paper :
A dry litmus paper will not show any effect in the presence of dry HCL due to the absence of moisture (H+ions) in the litmus paper, whereas on putting a drop of water, the blue litmus paper immediately turns to red due to the presence of water in it hence presence of hydrogen ions (H+ ions).
