How to compare the acidic and basic strength of different acids and bases. Explain with examples
Acid Strength: Acid strength is an acid's ability or tendency to lose a proton. Different acids should have different strengths. There are very few strong acids which are completely ionized in...

Explain Lewis acids and bases with suitable examples.
Lewis acids are lone pair (of e- ) accepters while Lewis bases are lone pair donators. AlCl3 is a Lewis acid while NH3 is a Lewis base.

Classify the following species into Lewis acids and Lewis bases and show how these act as such:
(a) Hydroxyl ion is a Lewis base as it can donate an electron lone pair (OH–). (b) Fluoride ion acts as a Lewis base as it can donate any one of...

In the preparation of H2SO4 by contact process, why is SO3 not absorbed directly in water to form H2SO4 ?
Because it forms a dense fog of sulphuric acid which does not condense easily.

What are strong and weak acids? In the following list of acids,
In aqueous solutions, strong acids ionise completely and provide hydronium ions. On the other hand, weak acids are partially ionised and an aqueous solution of same molar concentration provides a much smaller...
