Question

Assertion: Equivalent weight of a species can be written as molecular weight of species divided by valence factor.
Reason: Valence factor represents the valence in element, acidity in bases, basicity in acids and total charge on cation or anion in an ionic compound.

• A. Assertion is correct but Reason is wrong.
• B. Assertion is wrong but Reason is correct.
• C. Both Assertion and Reason are correct and Reason is correct explanation of Assertion
• D. Both Assertion and Reason are correct but Reason is not correct explanation of Assertion

Answer 1

The correct option is D Both Assertion and Reason are correct but Reason is not correct explanation of Assertion

Assertion: Equivalent weight of a species can be written as molecular weight of species divided by valence factor.
For an element the equivalent weight is the quantity that combines with or replaces 1.00797 grams (g) of hydrogen or 7.9997 g of oxygen; or, the weight of an element that is liberated in an electrolysis (chemical reaction caused by an electric current) by the passage of 96,500 coulombs of electricity.
Reason: Valence factor represents the valence in element, acidity in bases, basicity in acids and total charge on cation or anion in an ionic compound.
It is a whole number that represents the ability of an atom or a group of atoms to combine with other atoms or groups of atoms. The valence is determined by the number of electrons that an atom can lose, add, or share.
Thus both Assertion and Reason are correct but Reason is not correct explanation of Assertion.
