Question

I need help filling out this table for the active ingredients listed and how they would react in all of these tests.

Active Ingredient AgNO3 (aq) PbNO3 (aq) BaCl2 (aq) 1M HCI (aq) TM NaOH (gg) lodine Acetic Acid Flame Test Cornstarch NaHCO3 Acetylsalicylic Acid MgSO4 NaOH CaCo3

The options for the tests are:

For AgNO3, PbNO3 and BaCl2: white precipitate or no precipitate

For HCl, NaOH and Acetic Acid: no reaction or gas produced

For Iodine: brown solution, clear solution or blue-black solution

And for the flame test: no colour, purple flame, green flame, yellow-orange flame, or white flame

Thanks!

I asked this same question before and got this answer, and every column incorrect just to help narrow the solution down.

Answer 1

1. AgNO3

Silver nitrate when reacts with soluble carbonates like NaHCO3 and CaCO3 gives white precipapte . It also reacts with acetylsalicylic acid, MgSO4 and NaOH to form a precipitate. They don't give precipitate with cornstarch.

2. PbNO3

Lead nitrate when reacts with soluble carbonates like NaHCO3 and CaCO3 gives white precipapte . It also reacts with acetylsalicylic acid, MgSO4 and NaOH to form a precipitate. They don't give precipitate with cornstarch.

3. BaCl2

Barium Chloride when reacts with soluble carbonates like NaHCO3 and CaCO3 gives white precipapte . It also reacts with MgSO4 and NaOH to form a precipitate. They don't give precipitate with cornstarch and acetylsalicylic acid.

4. HCl

HCl reacts with all other reactants to produce gas except with NaOH. HCl do not react with cornstarch.

5. NaOH

NaOH reacts only with corn starch to produce gas.

6. Acetic Acid

Acetic acid do not produce gas with NaOH and acetyl salicylic acid.

7. Iodine gives blue black solution with cornstarch and NaHC03. Iodine gives a clear solution with all the other reactants.

8.On flame test, acetyl salicylic acid gives yellow-orange flame with CaCO3, acetyl salicylic acid,NaOH & NaHCO3. It gives no flame with cornstarch.
