1.	Aluminium displaces hydrogen from dilute HClwhereas silver does not. The e.mf. of a cellprepared by combining AlVAl andAg/Ag is 2.46 V. The reduction potential ofsilver electrode is +0.80 V. The reductionpotential of aluminium electrode is A (K.CE.T)1) + 1.66 V3) + 3.26 V3+2) 3.26 V4)-1.66 V
Answer» First the reduction potential of Aluminum will be -ve then it's Standard value without considering problem values is 1.66 hence u know the value now.option(4) is the correct answer
