Greetings everyone!
I have a question I would like to ask u guys. I have encountered this in my GRE Chemistry exam recently. It deals with the reaction of BaSO4 + HCl. Shall it form BaCl2 + H2SO4? My friend says that its impossible to form H2SO4 in the reaction. I would like to know the mechanism of this reaction? Any responses will be highly appreciated.
Thanks a lot,
Tashkent

No the reaction will not proceed and hence No H2SO4.

I don't know, but Hard acids and hard bases like H+ and Cl- typically like to stay with each other.

no reaction would occur. the barium is way too cationically active and would rather stay with the much more negative sulfate

BaSO4 is slightly dissolved in concentrated HCl because an equlibrium reaction
SO4(2-) + H(+) = HSO4(-)
take place (K2 of H2SO4 equals to 1.2x10^-2) ),
but this reaction cannot any practical use.
