Question

acid pr heat ka effect pdta h ya nhi.??? tell me answer fast

Answer 1

heyy dear ur answer...........

ys of course acid affected by heating i explain to u with example of hcl...

If you boil diluted HCl, the vapor will almost consist of pure water at first. The acid concentration in the boiling liquid will rise until it reaches the azeotropic concentration roughly at about 20%. It will not increase further

At this concentration the vapor has the same concentration as the boiling liquid. The liquid and the vapor concentration are in equilibrium. In physical chemistry we say the mixture behaves like a pure liquid.

If you boil concentrated (fuming) HCl the excess of physically dissolved HCl (covalent, not dissociated HCl) will evaporate first (comparable to the CO2 in a soda bottle when opening it) and the concentration will go down to about 20% again...........

hope this will help u.............@kundan
