Out of the following pairs, predict with reason which will allow greater conduction of electricity :
`1M CH_3COOH` solution or `0.1 M CH_3COOH` solution on dilution.

(a) Out of the following pairs , predict with reason which pair will allow greater conduction of electricity: (i) silver wire at 30^@ or silver wire at 60^@ C (ii) 0.1M CH_(3)COOH solution or 1M CH_(3)COOH solution (iii) KCl solution at 20^@ C or KCl solution at 50^@ C . (B) Give two points of differences between electrochemical and electrolytic cells.

Give reasons: Conductivity of CH3COOH dereases on dilution

Calculate the pH at the equivalence point when a solution of 0.01 M CH_3COOH is titrated with a solution of 0.01 M NaOH. pK_a of CH_3COOH is 4.74.

When the following is added to 20 ml of 0.1 M CH_(3)COOH + 20 ml 0.1 M of CH_(3)COONa . The pH of the solution does not change

The pH of the solution obtained on neutralisation of 40 mL 0.1 M NaOH with 40 ml 0.1 M CH_(3)COOH is
