The dissociation constants for acetic acid and HCN at 25o C are 1.5 X 10-5 and 4.5 x 10-10 respectively. The equilibrium constant for the equilibrium

Although the addition of sulphuric acid will precipitate lead sulphate, the addition of acetic acid will ensure a complete precipitation of sulphur in the form of lead sulphate due to...

(C) 5% – 8% acetic acid in water

(D) P, Q and R

(B) Acetic acid turns red litmus blue but it does not affect blue litmus.

The correct answer is (B) ii

(b) : Molar heat capacity = Molar mass × specific heat capacity So, the molar heat capacities at constant pressure and constant volume will be 28CP and 28CV respectively Therefore, 28CP –...

Acetic acid is colourless liquid. It is miscible/ soluble in water. On adding a pinch of sodium hydrogen carbonate, Brisk effervescence is observed. Evolution of a colourless/ odourless gas.

(a) : For spontaneous process, ΔG = –ve Now ΔG = –RT ln K When K > 1, ΔG = –ve Again ΔGº = – nFEº When Eº = +ve, ΔGº = –ve

The correct answer is (c) Cp - Cv

(a) there will be no neutral temperature (b) there will be no inversion temperature
