(a) A strong acid is a acid which have lesser pH value but higher amount of H+ ions.
A weak acid is a acid which have higher pH value but lesser amount of H+ ions.
(b) The liquid that fall on the Student's hand is an acid and when we put water into acid then there is an opposite reaction. Like the student who have put water into acid and the tube immediately cracked.
A student working in the laboratory added some water to a syrupy liqiud taken in a tube. The tube immediately cracked and the liquid which escaped out of it, produced blisters on the skin of the student. ... That is why the tube cracked and the vapours of the escaping acid produced blisters on the skin.
A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. ... At the same concentration, weak acidshave a higher pH value thanstrong acids.
The syrupy must be a strong acid
When he add water to it, exothermic reaction is taken place.
As it exhothermic reaction, lot of heat is produced and the apparatus is broke.
This syrupy liquid must be concentrated sulphuric acid
Concentrate sulphuric acid has the following properties
a) it is colourless
b) it is adourless
c) it is syrupy liquid
d) it is soluble in water and the reaction is highly exothermic
e) Even in moderate concentration, it is very dangerous when it gets into contact with the skin and can produce blisters
The syrupy liquid in th etube was concentrated sulphuirc acid. Since it has great afinity for water, the energy released was in the from of heat. That is why the tube cracked and the vapours of the escaping acid produced blisters on the skin.
