(i) The pH of HCl is between 0 and 2.
(ii) the presence of Carbon Dioxide turns lime water milky or sees a white precipitate form on the surface of the lime water. Lime water is CaOH and when it reacts with Carbon Dioxide it forms a white solid (precipitate) Calcium Carbonate.

Ca(OH)_(2) _((l)) + CO_(2) _((g)) -----\ \textgreater \ CaCO_(3) _((s)) + H_(2)O_((l))
