Statement The equivalence point refers the condition where equivalents of one species reacts with same number of equivalent of other species.
Explanation The end point of titration is exactly equal to equivalence point.

A

`S` is correct but `E` is wrong.

B

`S` is wrong but `E` is correct.

C

Both `S` and `E` are correct and `E` is correct explanation of `S`

D

Both `S` and `E` are correct but `E` is not correct explanation of `S`.

Text Solution

Verified by Experts

The correct Answer is:
A
The equivalent point is nearly same but not exactly same to end point. However for all partical purposes the two are taken same.

The equivalent weight of a species if acts as oxidant or reductant should be derived by : Eq. weight of oxidant or reductant = ("Mol. wt. of oxidant or reductant")/{("Number of electrons lost or gained by one"),("moleculae of oxidant or reductant"):} During chemical reactions, equal equivalents of one species react with same number of equivalents of other species giving same number of equivalent of products. However this is not true for reactants if they react in terms of moles. Also Molarity can be converted to normality by multiplying the molarity with valence factor or 'n' factor.
