Error in carbonate ion test. Need to remove "Colour of Precipitate is Observed and Recorded"
ReplyDeleteSo, whats the difference between Carbon dioxide test and Carbonate ions test they both have the same results
ReplyDeleteyou add HCl first, so if a carbonate is present, the carbonate becomes C02, which you can then test for
DeleteIn the Carbonates test could you please tell me why H is present instead of HCl in the equation.
ReplyDeletethe Cl- is just floating around in the solution, together with whatever the carbonate was bonded to before
