Preparation And Properties Of Acids
The acids which undergoes complete ionisation when dissolved in water and
furnish large concentration of H+ ions are called strong acids.
Ex:- Strong acids :Sulphuric acid \(
(H_2 SO_4 )
\) Hydrochloric acid (HCl) Nitric acid (\(
(HNO_3 )
\)
The acids which undergoes partial ionisation when dissolved in water and furnish less concentration of H+ ions are called weakacids.
Weak acids : Carbonic acid \(
(H_2 CO_3 )
\) Acetic acid (CH3COOH )
Nitrous acid \(
(HNO_2 )
\) Phosphoric acid (H3POD)
Phosphorous acid (\(
(H_3 PO_4 )
\)
The acids are categorized as concentrated and dilute acids. If you add acid to least quantity of water it is called concentrated acid while added to high quantity of water is called diluted acid. Should be careful which adding water to an acid, because acid gives
out heat, fumes and some times bursts into flame. Glass container may break due to excessive heat.
Acids in your body:
Hydrochloric acid, made in the stomach, kills most of the germs that you swallow with your food and it also makes the conditions right for the food in your stomach to be digested. Lactic acid made by bacteria feeding on the sugars, may give you tooth decay.
