Question

The law of reciprocal proportions was given by
1. Richter
2. Charles
3. Avogadro
4. Lavoisier

Answer 1

Correct Answer - Option 1 : Richter

Concept:

• Law of reciprocal proportions: It states that, if two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they do so are either the same as or a simple multiple of the ratio of the masses in which they combine.
  • The law was proposed by Jeremias Richter which he used for neutralization of ratios of metals with acids.
  • It was stated that:
    "When two substances A and B are chemically reactive with the other two substances C and D, then the ratio of the quantities of C and D has the same amount of A as the ratio of the quantities of C and D has with B" 

Explanation:

• The law of reciprocal proportions is also called the law of equivalent proportions or the law of permanent ratio.
• This law is also widely used as the basic law of stoichiometry.
• From the above discussion, it's clear that the Law of reciprocal proportions is given by Jeremias Richter.

So, the correct option is Jeremias Richter.
