This section is based on Statement I and Statement II. Select the correct anser from the codes given below
Q.
Statement I : In the conductometric titration of CH3COOH with NaOH,conductance first increases slowly and after complete reaction of CH3COOH, it increases rapidly as shown
                                        
Statement II : Initial increase in conductance is due to hydrolysis of salt  formed.
  • a)
    Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I  
  • b)
    Both Statement I and Statement II are correct but Statement II is not the correct explanation of Statement I
  • c)
    Statement I is correct but Statement II is incorrect
  • d)
    Statement II is correct but Statement I is incorrect
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Statement TypeThis section is based on Statement I and Statement II. S...

As CH3COONa is formed, it is hydrolysed at the same time forming CH^COOH (weak acid) and NaOH (strong base). Due to formation of strong base, conductance increases at every addition of NaOH. After CH3COOH is completely neutralised further addition of NaOH causes rapid increase in conductance (no CH3COOH at this stage)

Thus, both Statements I and II are correct and Statement II is the correct explanation of Statement I.

Consider a solution of CH3COONH4 which is a salt of weak acid weak base. Theequilibrium involved in the solutions are :If we add these three reactions, then the net reaction isBoth CH3C00- and NH4 get hydrolysed independently and their hydrolysis depends on(i) their initial concentration(ii) the value of Kh which is Since both of the ions were produced from the same salt, their initial concentrations are same . Therefore unless untial the value of Kw/Kaand Kb is same, the degree of hydrolysis of ion cant be same.To explain why we assume that degree of hydrolysis of cation and anion is same, we need to now look at the third reaction i.e., combination of H+ and OH ions. It is obvious that this reaction happens only because one reaction produced H+ ion and the other produced OH ions. We can also note that this reaction causes both the hydrolysis reaction to occur more since their product ions are being consumed. Keep this thing in mind that the equilibrium which has smaller value of equilibrium conxtant is affected more by the common ion effect. For the same reason if for any reason a reaction is made to occur to a greater extent by the consumption of any one of the product ion, the reaction with the smaller value of equilibrium constant tends to get affected more.Therefore we conclude that firstly the hydrolysis of both the ions ocurs more in the presence of each other (due to consumption of the product ions) than in each other is absence. Secondly the hydrolysis of the ion which occurs to a lesser extent (due to smaller value of Kh) is affected more than the one whose Kh is greater. Hence we can see that the degree of hydrolysis of both the ions would be close to each other when they are getting hydrolysed in the presence of each other.Q.In a solution of NaHCO3 , the amphiprotic anion can under ionization to form H+ ion and hydrolysis to from OH ion.To calculat PH, suitable approximation is
