While preparing dilute sulphuric acid from concentrated sulphuric acid in the laboratory, the concentrated sulphuric acid is added slowly to water with constant stirring.
Answers
Answer:
This is the correct method
Explanation:
If water is added to acid then the heat generated would would creating more heat energy and the beaker could break and cause the acid to splash out causing harm.
Therefore acid is added to water with constant stirring.
Answer:
Here's your answer....
Explanation:
concentrated concentrated sulphuric acid is hazardous, highly corrosive chemical. itit has a higher density than water and is hygroscopic which means that it absorb water from air.
in the process of dilution of concentrated sulphuric acid with water very large amount of heat is liberated.
as a result water gets evaporated instantaneously along with splashing of acid which may cause an accident.
to avoid this required amount of water is taken in glass container and a small quantity of concentrated sulfuric acid at the time is added with stirring.
therefore only small amount of heat is liberated at a time.
