(a)[2]
What method can be used to separate M from L?
(b)[2]
Two separate test-tubes each receive a sample of a solution of L. Tests are done and observations recorded. Identify both ions present in L.
(c(i))[2]
Dilute hydrochloric acid is added to solid M, producing carbon dioxide gas. State a test and the observation that would identify carbon dioxide gas.
(c(ii))[1]
Name the negative ion present in M.
(d)[3]
Solid M reacts with dilute hydrochloric acid to make a solution. Describe a test and observations to show that this solution contains calcium ions.
