Question1: Which sodium salt(s) ( NaF, NaBr, and/or NaI) will react with chlorin

Question

Question1:

Which sodium salt(s) ( NaF, NaBr, and/or NaI) will react with chlorine to produce sodium chloride? What is the balanced net ionic equation, the spectator ion(s), the oxidizing agent and the reducing agent? What would this look like if you did this in the lab?

Question2:

What is one metal ion in solution that will oxidize magnesium?

What is the balanced net ionic equation, the spectator ion(s), the oxidizing agent and the reducing agent? What would this look like if you did this in the lab?

Explanation / Answer

#1 NaBr would react with Cl2 gas to form NaCl

2Br- + Cl2 ---> 2Cl- + Br2

spectator ion = Na+

Oxidizing agent = Cl2

reducting agent = Br-

NaBr is yellow is color whereas, NaCl is white is color. So the solution color change would depict reaction is done.

#2 Fe(NO3)2 would oxidize Mg.

Mg + Fe(NO3)2 ----> Mg(NO3)2 + Fe

spectator ion : NO3-

oxidizing agent = Fe(NO3)2

reducing agent = Mg

Fe(NO3)2 is brows=nish-yellow color soluition which change to colorless solution upon conversion to Mg(NO3)2
