A galvanic cell has two electrodes, `X^(n+)|X and Y^(n+)|Y`. It is seen that current flows from Y electrode towards X electrode. Between these two electrodes, which one has a higher reduction potential? Explain.

What will be the standard reduction potential of an electrode, if its standard oxidation potential is x volt? Explain.

Standard reduction potential of the electrode X|X^(+) is +0.80V. If this electrode is connected to a standard hydrogen electrode, What will be the direction of electron flow in the outer circuit?

Show that if the two electrodes of an electric cell are short circuited then no potential difference will exist between them.

Write down the reaction occuring at the two electrode when current is drawn from a Daniell cell.

You are given two electrodes whose standard reduction potentials are also given. Which one should you use as cathode and as anode?

If X and Y are two sets such that X ∪ Y has 50 elements, X has 28 elements and Y has 32 elements, how many elements does X ∩ Y have ?

If the relation between two variables x and y is 2x - 3y = 4, what is the relation between their ranges?

Find the angle between the two lines x-sqrt3y=3 and sqrt3x-y+1=0

If X and Y are two sets such that (X cup Y) has 60 elements ,X has 38 elements and Y has 42 elements, how many elements does (X cap Y) have ?

The concentration of each of Y^(-) and Z^(-) in a solution is 1 M. At 25^(@)C , a gas X at a pressure of 1 atm is allowed to pass through the solution. If the values of standard reduction potentials of X, Y and Z follows the order Z gt X gt Y , then which one between Y^(-) and Z^(-) would be oxidised by X?
