Definition Of Law Of Definite Proportions
Definition Of Law Of Definite Proportions. In chemistry, the law of definite proportions indicates that compounds will always be composed of the same elements in t. Two or more elements when united to form a new substance do so in a constant and fixed proportion by weight.
The law of definite proportions dictates that a name is always associated with a specific ratio of elements found in a chemical compound. Law of definite proportions, statement that every chemical compound contains fixed and constant proportions (by mass) of its constituent elements. Every definite compound always contains the same elements in the same proportions by weight.
Definition Of Law Of Definite Proportions.
For example, oxygen makes up about 8 / 9 of the mass of any sample of pure water, while hydrogen makes. Two or more elements when united to form a new substance do so in a constant and fixed proportion by weight.

This Ratio Does Not Depend On The Source Of The Chemical Compound Or The Method Through Which It Was Prepared.
The definition of the law of definite proportions is that in any chemical compound, the mass ratio of its elements is constant. Law of definite proportions, statement that every chemical compound contains fixed and constant proportions (by mass) of its constituent elements. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass.
So, If A Compound Is Made By Combining 1/4 From One Chemical And The Remaining 3/4 From Another Chemical, These Proportions Will Always Hold True, Regardless Of The Amount Of Chemicals Added.
If the ratio of elements is different from that specific ratio, then it is not the same compounds and therefore has a different name. The definition of the law of definite proportion, sometimes called proust's law is the law in chemistry where a chemical compound always has the same proportion of elements by mass. Every definite compound always contains the same elements in the same proportions by weight.
