what is e°cell for the following reaction? 2 ag(s) sn2 (aq) → 2 ag (aq) sn(s) ag (aq) e– → ag(s) e° = 0.80 v sn4 (aq) 2e– → sn2 (aq) e° = 0.13 v sn2 (aq) 2e– → sn(s) e° = –0.14 v

h let me think

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
