This Law was given by Joseph Proust.
According to this law, “A chemical compound always consists of the same elements in the same ratio by weight”.
For example, samples of CO2 obtained by different methods always contain the same elements, i.e., carbon and oxygen in the same ratio, i.e., 3: 8 by weight.
Wet Chemistry or Wet Chemistry Techniques are used to perform analysis in the liquid stage. It is also called Bench Chemistry since many of the tests done are performed at a laboratory bench. Many high school and college labs teach pupils basic Wet Chemistry Techniques. History Of Wet Chemistry Techniques Before the era of computational…
Alkyl Halides concepts are essential to learning for every level in chemistry courses. Here, we have compiled many Alkyl Halides quizzes free for students of grades 11 and 12. We hope you will find this very useful for your regular exam preparations and entry tests at undergraduate levels, particularly for medical and engineering students (MDCAT,…
Matter: Anything which possesses mass and occupies space is called matter. States of Matter: Matter exists in 5 states. (i) Solid (More common form of matter) (ii) Liquid (Less common form of matter) (iii) Gas (Simplest form of matter) (iv) Plasma (Advanced form of matter) (v) Bose-Einstein Condensates Definition of state of matter Solid…
Millikan, in 1909, determined the charge on electron by the apparatus consisting of a metallic chamber having two parts. The chamber is filled with air whose pressure can be adjusted by a vacuum pump. There are two electrodes A and A’. These electrodes are used to generate an electrical field in the space between the…

The general gas equation is not applicable to real gases at the all the temperature .and pressure. In order to make it applicable to real gases Van der Waals’ made correction in volume and pressure of the gases and derived an equation known as Van der Waals’ equation. Volume Correction The actual volume of gas…
