Question

Reagent Matching 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. Disodium EDTA (Na2EDTA) 6M Hydrochloric Acid (HCl) 0.1M sodium carbonate (Na2 CO3) Zinc Nitrate (Zn(NO3)2 Lead chloride (PbCl2(s)) OH-, CO32-. and PO 43- Barium Nitrate (Ba(NO3)2) Colbalt Nitrate (Co(NO3)2) Silver chloride (AgCl(s)) Na+, NO3-, and NH4+ Silver Nitrate (AgNO3) Aluminum Nitrate (Al(NO3)3) NH4+(aq) and OH-(aq) Anion 1M ammonium hydroxide (NH4OH) Cation 6M Nitric Acid (HNO3) Lead Nitrate (0.1M Pb(NO3)3) None of the above Salts containing these ions are often insoluble in water and form precipitates. In test A1 you add this reagent to tests where a precipitate forms. The name for a positively charged ion is.... Lead Nitrate (Pb(NO3)2) will combine with hydrochloric acid (HCl) to form what white precipitate? This reagent is added fresh samples in test A3 where there was no reaction in tests A1 or A2. In test B1 this is the first reagent added to the sample.

Explanation / Answer

Salts containing these ions are often insoluble in water and form precipitates. = F ) OH-, CO32-, and PO43-

The name for positively charged ion is = P) cation

Lead Nitrate (Pb(NO3)2) will combine with hydrochloric acid (HCl) to form what white precipitate

= E)Lead chloride (PbCl2(s))
