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.

A Anion B 0.1M sodium carbonate (Na2CO3) C Lead Nitrate (0.1M Pb(NO3)3) D Colbalt Nitrate (Co(NO3)2) E Na+, NO3-, and NH4+ F Silver chloride (AgCl(s)) G Disodium EDTA (Na2EDTA) H 6M Nitric Acid (HNO3) I Aluminum Nitrate (Al(NO3)3) J Lead chloride (PbCl2(s)) K Barium Nitrate (Ba(NO3)2) L 1M ammonium hydroxide (NH4OH) M Cation N Silver Nitrate (AgNO3) O 6M Hydrochloric Acid (HCl) P OH-, CO32-, and PO43- Q NH4+(aq) and OH-(aq) R Zinc Nitrate (Zn(NO3)2
s None of the above


This reagent is added to fresh solutions in test B2 where there was no reaction in test B1.

Salts containing these ions are often insoluble in water and form precipitates.

Salts containing these ions are nearly always soluble in water.
In test A1 you add this reagent to tests where a precipitate forms.
in test B2 this reagent is added to tests after a precipitate is formed.
Concentrated Ammonia (NH3) will combine with water to form these ions in solution.

Explanation / Answer

Answer )

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

Salts containing these ions are nearly always soluble in water. = E) Na+, NO3-, and NH4+

Concentrated Ammonia (NH3) will combine with water to form these ions in solution = Q) NH4+(aq) and OH-(aq)
