Answer:

C = 0.08M

Explanation:

molar mass of AlCl3

Al =27

Cl = 35.5

27+3(35.5) =133.5g/mol

n= mass/Molar mass

n =CV

CV = mass/molar mass

C x 500 x 10^-³ = 5/133.5

C x 500 x 10^-³ = 0.04

C = 0.04/500 x 10^-³

C = 0.08M

Write the net cell equation for this electrochemical cell. Phases are optional. Do not include the concentrations. Co ( s ) ∣ ∣
Tatiana [17]

Answer: The overall equation will be Co(s)+2Ag^+(aq)\rightarrow Co^{2+}(aq)+Ag(s)

Explanation:

The representation is given by writing the anode on left hand side followed by its ion with its molar concentration. It is followed by a salt bridge. Then the cathodic ion with its molar concentration is written and then the cathode.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Anode : Co(s)\rightarrow Co^{2+}(aq)+2e^{-}

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Cathode : Ag^+(aq)+e^{-1}\rightarrow Ag(s)  \times 2

The number of electrons lost must be equal to the number of electrons gained , thus overall equation will be :

Co(s)+2Ag^+(aq)\rightarrow Co^{2+}(aq)+Ag(s)
