Question

Potassium combines with two isotopes of chlorine ${(}^{35}Cl$ and ${}^{37}Cl)$ respectively to form two samples of $KCl$. Their formation follows the law of:

• A. constant proportions
• B. multiple proportions
• C. reciprocal proportions
• D. none of the above

Answer 1

The correct option is B multiple proportions

Law of multiple proportions states that when

two elements combine with each other to

form more than one compound, the weights

of one element that combine with a fixed

weight of the other are in a ratio of small

whole no.

hence the formation of KCl (two samples)

Ans - 'B'
