Question

What type of acid is \[HF\] ?

Answer 1

Hint: Acids are defined as substances that can either donate a proton or accept an electron in a chemical reaction. There are certain properties that are shown by acids such as, they can turn litmus paper red, helps in the neutralisation of alkalis, and also dissolves some of the metals.

Complete Step by Step Solution:
An acid that is capable of donating a proton is termed ‘Bronsted-Lowry acid’ and the acid that donates the electron by forming a covalent bond with the pair of electrons is known as ‘Lewis acid’.

Acids usually show a ph level of less than 7. The lower the ph gets, the stronger is the acid, and also the concentration of hydrogen ions in its aqueous solution would be more. They are usually sour in taste. The strength of the acid is determined by its ability to lose a proton. The quicker it loses the proton, the stronger the acid is.

\[HF\] is a weak acid as it has a lesser dissociation constant as compared to other strong acids, also the ability of this acid to lose a proton is lesser as compared to other stronger acids.

Note: Acids also exhibit certain properties such as:
1) Acids are very good conductors of electricity
2) They have the tendency to corrode other materials.
3) They are usually sour in taste and can turn litmus paper red.
4) When acids are reacted with certain metals, they often liberate hydrogen gas.
5) It doesn’t matter if the acid is weak or strong, their pH will always be less than 7.
