Question

The question is in an image. You need to use "CER" which is in one of the images and the reference table F (And maybe some others in case you need it.) which is in another of the images. "CER" means 3 words: Claim (The answer), Evidence (Why the answer is right) and Reasoning (Connect answer to evidence).

Answer 1

NH₄Cl (aq) + AgNO₃ (aq) ---> AgCl (s) + NH₄NO₃ (aq)

Will the reaction between NH₄Cl and AgNO₃ form a precipitate?

CLAIM:

Yes, the reaction between NH₄Cl and AgNO₃ will form a precipitate, AgCl according to the equation below:

NH₄Cl (aq) + AgNO₃ (aq) ---> AgCl (s) + NH₄NO₃ (aq)

EVIDENCE:

The reference table F (Solubility Guidelines for Aqueous Solutions) states that all halides are soluble except when they are combined with Ag⁺, Pb²⁺ or Hg²⁺ .

REASONING:

The reaction between NH₄Cl and AgNO₃ makes AgCl as a product. The reference table F states AgCl is insoluble, therefore. a precipitate is produced.
