Avoltaic cell consists of a strip of cadmium metal in a solution of cd(no3)2 in one beaker, and in the other beaker a platinum electrode is immersed in a nacl solution, with cl2 gas bubbled around the electrode. a salt bridge connects the two beakers. part a which electrode serves as the anode, and which as the cathode? which electrode serves as the anode, and which as the cathode? cd serves as the cathode, pt as the anode. pt serves as the cathode, cd as the anode. request answer part b does the cd electrode gain or lose mass as the cell reaction proceeds? does the electrode gain or lose mass as the cell reaction proceeds? the cd electrode will gain mass as the cell reaction proceeds. the cd electrode will lose mass as the cell reaction proceeds. request answer part c write the equation for the overall cell reaction.

1. Pt serves as the cathode and Cd as the anode

2. Cd electrode loses mass as the cell reaction proceeds.  

3. The overall cell reaction is mentioned in the explanation column.  

Explanation: 1. The electrode with positive reduction value serves as cathode, that is, Pt, while, the electrode with negative reduction value functions as anode, that is, Cd.  

2. The oxidation takes place in the Cd electrode, which is anode, and it gets oxidized to Cd²⁺ (aq). Hence, Cd electrode loses mass as the cell reaction moves forward.  

3. Cell reaction:  

Cd(s) = Cd²⁺ (aq) + 2e⁻

Cl₂ (g) + 2e⁻ = 2Cl⁻ (aq)

Cd(s) + Cl₂(g) = Cd²⁺ (aq) + 2Cl⁻ (aq)

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
