^^^Yes, they're both equally important. There seems to be a lot of questions involving them in almost all past papers.
Their tests and results are EXTREMELY important. In fact most of Paper 6 is all about that section.

Umm, in B(ii) and (iii), a (iii) and a (iv) are repeated, which are tests for the presence of chlorides, bromides or iodides.

Since in (b) the result for both is yellow, especially bright yellow with lead, it IS and iodide salt.
So, Potassium Iodide.

In B(i) it was added to distilled water as tests can only be applied when the salt is in solution, to show a result.

^^I don't think so, I mean all you need from that part is the probably the tests for Alkenes and Alkanes etc. (And probably the fermentation and fractional distillation)

Question: When we say a substance is soluble, we mean that it dissolves well in water or all other solvents?
