Vedclass · Answer

(N/A) The action of these substances on litmus paper depends on their acidic or basic nature. Acids turn blue litmus red,while bases turn red litmus blue. Dry $HCl$ gas does not show acidic properties because it lacks $H^+$ ions in the absence of water. Moistened $NH_3$ gas acts as a base $(NH_4OH)$. Lemon juice,carbonated soft drinks,and curd are acidic. Soap solution is basic.
