Question

Determine whether a solid forms when solutions containing the following salts are mixed. If so, write the ionic equation and the net ionic equation.
Part A: KCl and Na2S Express your answer as a chemical equation. Identify all the phases in your answer. Enter no reaction if no reaction occurs.
Part B: Net ionic equation:
Part C: AgNO3 and K2S Express your answer as a chemical equation. Identify all the phases in your answer. Enter no reaction if no reaction occurs. Express your answer as a chemical equation. Identify all the phases in your answer. Enter no reaction if no reaction occurs.
Part D: Net ionic equation:

Explanation / Answer

A) given KCl and Na2S

the possible products K2S and NaCl are soluble

so

no solid is formed

all the ions in the solution are soluble

so

no reaction will take place in this case

B) no reaction

C)

the balanced chemical reaction is

2AgN03 (aq) + K2S (aq) --> Ag2S (s) + 2 KN03 (aq)

now

the ionic equation is given by

2 Ag+ (aq) + 2N03- (aq) + 2K+ (aq) + S-2 (aq) --> Ag2S (s) + 2K+ (aq) + 2 N03- (aq)

D)

now cancel out the common ions to get the net ionic equation

2 Ag+ (aq) + S-2 (aq) ---> Ag2S (s)
