Watch some of the important Chemistry Bits below.
1-Compounds responsible for temporary hardness of water are Bicarbonates of Calcium and Magnesium
2- The catalyst used for the synthesis of Sulphuric Acid by Contact Process is Platinum (Pt)
3-The important metal used with iron to produce stainless steel is Chromium.
4-Most abundant metal in earth’s crust is Aluminium
5-The radioactive element most commonly detected in humans is Potassium – 40.
6-The name ‘catalyst’ was given by Berzelius.
7- Solutions are classified into aqueous and non-aqueous solutions, based on the Nature of solvent
8-Tyndall effect is exhibited by Colloidal solutions
9- The particle size of a colloidal solution is 10 Å – 2000 Å
10-Chalk powder in water is an example of suspension
11-The dispersed phase in a colloidal solution is Solute
12-Brownian movement explains the kinetic property of colloidal solutions.
13-According to Henry’s Law, in gases, an increase in pressure increase Solubility
14- Henry’s law relates solubility of solvents with pressure
15-When sunlight passes through the window of a house, the dust particles scatter the light making the path of the light visible. This phenomenon is called as Tyndall effect
16- In the Beginning of the 20th century, Matter Wave concept was introduced by Broglie
17-Avogadro’s hypothesis relates volume of gases and number of molecules
18-The metal used to recover copper from a solution of copper sulphate is Fe
19-The metallurgical process in which a metal is obtained in a fused state is called smelting
20-The law which states that the amount of gas dissolved in a liquid is proportional to its partial pressure is Henry’s law
21-The most commonly used bleaching agent is Chlorine.
22-The nuclear particles which are assumed to hold the nucleons together are mesons
23-The metal that is used as a catalyst in the hydrogenation of oils is Ni
24-The Latin word Formica means ant. The name formic acid is derived from this Latin word because this acid was first obtained by the distillation of ants
25-The inherited traits of an organism are controlled by DNA molecules
