Definition of equivalent weight

Post by Dhamnekar Winod »

1)equivalent : an equivalent of an acid is the mass of acid required to provide one mole of hydrogen ions in a reaction; an equivalent of a base is the mass of base required to react with one mole of hydrogen ions. An equivalent of an oxidizing agent or of a reducing agent is the mass of the agent that combines with or releases one mole of electrons, respectively.

2)Equivalent weight of an acid or a base is its formula weight divided by the number of protons it donates or accepts

Are these two definitions of equivalent weight 1) and 2) are equal in meaning or can we use them interchangeably?

If yes, how? Show it by examples
Any science consists of the following process. 1) See 2)Hear 3)Smell,if needed 4)Taste, if needed 5)Think 6)Understand 7)Inference 8)Take decision [Believe or disbelieve, useful or useless, true or false, cause or effect, any other criteria]

Yes it is. It guides from molarity to normality or equivalent concentration.
Compare HCl and H2SO4 , if neutralised with 1 M NaOH.
