(ii) Strong or concentrated acids or their fumes often produce a stinging feeling on mucous membranes
(iii)Change the color of pH indicators as follows: turn blue litmus and methyl orange red, turn phenolphthalein colorless
(iv)React with metals to produce a metal salt and hydrogen
(v) React with metal carbonates to produce water, CO2 and a salt
(vi)React with metal hydroxides and metal oxides to produce water and a salt
(vii) Conduct electricity, depending on the degree of dissociation in aqueous solution
(viii) Produce solvonium ions, such as oxonium (H3O+) ions in water

Properties of Base:
(II)Slimy or soapy feel on fingers, due to saponification of the lipids in human skin
(III) Concentrated or strong bases are caustic (corrosive) on organic matter and react violently with acidic substances
(IV) Aqueous solutions or molten bases dissociate in ions and conduct electricity.
(V) Reactions with indicators: bases turn red litmus paper blue and
