Explain what is the sign of the cathode in a galvanic cell

Reference no: EM13253646

Use the Nernst equation to determine the cell potential, EoCell, of the galvanic cell consisting of the two redox couples,

Ag+ (0.0010M) + e- <-> Ag
Cr3+ (0.1M) + 3e- <-> Cr

a) Which is the anode, and which is the cathode?

b) If the Ecell measures 1.40 V, what is a more accurate molar concentration of Cr3+, assuming the molar concentration of Ag+ is accurate?

c) What is the sign of the cathode in a galvanic cell? What type of reaction occurs at the cathode?
