# What is the law of multiple proportions?

Jan 1, 2018

Well, it is an empirical law that dates back to old Dalton....

#### Explanation:

As originally proposed....

$\text{If two elements form more than one compound between them,}$
$\text{then the ratios of the masses of the second element which}$ $\text{combine with a fixed mass of the first element will be ratios of}$ $\text{small whole numbers....}$

And so if we compare $C O$, and $C {O}_{2}$, the $C : C$ ratio is $1 : 1$, and $C : O$ ratio is $1 : 2$...

What are the ratios for the oxides of sulfur?
