Question
Match the statement to the correct answer. (Some reagents can be used more than once.) The flowchart along with the report sheets in experiment 5 should be very helpful.

Explanation / Answer
This reagent is added fresh samples in test A3 where there was no reaction in tests A1 or A2 is Disodium EDTA (Na2EDTA) (C)
Mixing AgNO3 and NaCl will produce AgCl. (L)
AgNO3(aq) + NaCl(aq) -----------> AgCl(s) + NaNO3 (aq)
Ba(NO3)3 is the reagent added after 6M HCl during test B1 (F)
Lead Nitrate (Pb(NO3)2) will combine with hydrochloric acid (HCl) to form PbCl2(s). (I)
Pb(NO3)2 + 2HCl (aq) -----------------> PbCl2(s) + 2HNO3(aq)
In test A2 you add 1M NH4OH reagent to the test where a precipitate was formed. (Q)
The name for a positively charged ion is.... CATION. (P)
