Question

What is law of reciprocal proportion?​

Answer 1

The law of reciprocal proportions is one of the basic laws of stoichiometry. It relates the proportions in which elements combine across a number of different elements. It was first formulated by Jeremias Richter in 1791.

This law states that the proportions in which two elements separately combine with a third element are also the proportions in which they combine together.

Hope this helps :)

Answer 2

Law Of Reciprocal Proportion

$\red\implies$The law states that if two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they combine are either the same or are in simple multiple ratio of the masses in which they combine with each other .
