What is the standard reduction potential value of potassium in the EMF series?(a) +0.337 V(b) -2.925 V(c) -0.763 V(d) -1.662 VThis question was posed to me in an online interview.My query is from Eight Forms topic in chapter Eight Forms of Corrosion of Corrosion Engineering

Answer»

Right option is (B) -2.925 V

For explanation: STANDARD REDUCTION potential values of metal are measured against SHE, which is arbitrarily defined as ZERO. Standard reduction potential of potassium (K-K^+), ALUMINUM (Al-Al^+3), zinc (Zn-Zn^+2), copper (Cu-Cu^+2) are –2.925V, -1.662V, -0.763V and +0.337V respectively.
