What effect does the concentration of `H^+`(aq) ions have on the nature of the solution?

What is the concentration of a solution ?

If E^@ for copper electrode is +0.34V, how will you calculate e.m.f. value when the solution in contact with it is 0.1 M in copper ions? How does e.m.f. for copper electrode change when concentration of Cu^(2+) ion in the solution is decreased?

At what concentration of silver ions will this electrode have a potential of 0 volt?

Compound ‘A’ with molecular formula C_4H_9Br is treated with aq. KOH solution. The rate of this reaction depends upon the concentration of the compound ‘A’ only. When another optically active isomer ‘B' of this compound was treated with aq. KOH solution, the rate of reaction was found to be dependent on concentration of compound and KOH both. Write down the structural formula of both compounds ‘A’ and 'B’.

Compound ‘A’ with molecular formula C_4H_9Br is treated with aq. KOH solution. The rate of this reaction depends upon the concentration of the compound ‘A’ only. When another optically active isomer ‘B' of this compound was treated with aq. KOH solution, the rate of reaction was found to be dependent on concentration of compound and KOH both. Out of these two compounds, which one will be converted to the product with inverted configuration.

What is the effect of decreasing concentration on the molar conductivity of weak electrolyte?
