Question

A diprotic acid will have two equivalence points on its titration curve True False The buffer capacity of a buffer increase by increasing amount of both weak acid and conjugate base in solution increasing amount of only the weak acid increasing amount of only the conjugate base The K_p of a salt increases if the salt is dissolved strongly acedic solution with a common True False The reaction is exothermic and increases entropy The reaction is endothermic and reduces entropy The reaction is endothermic and increases entropy A spart process is reversersible True False melting The temperature does not change the entropy increases Both the temperature and the entropy increase The temperature does not change however the entropy decreases the temperature changes however the entropy stays the same A process is spat when the free energy change is positive True False.

Explanation / Answer

1) A ditropic acid will have two equivalence points on its titration curve - True

2) The buffer capacity of buffer increase by - increasing amount of NaOH

3) The Kp of a salt increases if the salt is dissolved in strongly acidic solution with common ion - True

4) A reaction is always spontaneous when reaction is exothermic & increase enrtopy.

5) A spontaneous process is irreversible - True

6) During melting - Both temperature & enrtopy increase.

7) A process is spontaneous when the free energy change is positive - True
