What are Colligative properties ?

Actually the word co-ligative itself reveals that (“co” means each other and “ligative” means related) These are the properties which are related to each other. The colligative properties are those properties that depend on the number of solute particles in a solution or a mixture. “These properties don’t depend upon the nature of particles “. Following are the colligative properties:- […]

Why are the noble gases chemically inert?

The outer or valence shell of these elements is complete. And they need not to make any bond. They do not share or transfer the electrons . Due to fully filled orbitals, Their ionisation enthalpies are also very high. So removing an electron from them is also very difficult. The examples of these are Helium, Neon, Argon, Krypton , Xenon […]

What is an electrophile?

See electrophile word is made up by the joining of two words “electro+phile. Electro means the “electron “ and phile means “loving” in short the electrophile is electron loving specie or attacking reagent that attacks only on the part of molecule with high electron density. For example :- H+ , H3O+ , NH4+   and BF3 etc

Terms related to mass

Atomic mass Atomic mass of an element is the relative mass as compared with an atom of carbon 12 and it is expressed in AMU. A.M.U. AMU is the Atomic mass unit and it is defined as the mass equal to 1 by 12th of the mass of carbon 12 isotope. 1 amu = 1.66056x 10-24 Molecular mass It is […]

A Short intro to acid, base and indicators.

Acid base and salts Acids:-  these are the substances that Are sour in taste. Turn blue litmus red. Give H+ ions. Can accept a pair of electrons. Base :- These are the substances that Are bitter in taste. Turn red litmus blue. Soapy in touch. Give OH– ions. How to recognise the acid and bases? To answer this question lets […]

What causes Ionic bonds to form? Use NaCl (table salt) as an example to explain the formation of ionic bonds.

it is a very common question and common example too. i would love to answer. Most people say it is the bond formed due to the transfer of electrons, but this explanstion is not complete. Ionic bond is the bond formed due to strong electrostatic forces of attraction between two oppositely charged ions. here is the complete reaction that takes […]
