Litmus test organic reaction

WebLitmus solution helps us identify solutions as acidic, basic, or neutral. WebAn acidic solution is any aqueous solution which has a pH < 7.0. Hence, solution B will liberate carbon dixoide gas on reaction with metal carbonates. [1 mark] (iii) The colour of litmus solution changes from red to blue in a basic solution. Solutions with a pH greater than 7 are basic. Hence solution A will turn red litmus solution blue.
