Question on Analytical Chemistry
Which one between (a) BaSO4 and (b) BaCO3 will be soluble in Hydrochloric Acid?
Answer:
It is BaCO3 that will be soluble in HCl, as it will release H2CO3, a weaker acid than HCl, while BaSO4 will release H2SO4, a stronger acid that HCl.
BaCO3 + 2HCl = H2CO3 + BaCl2 is possible as a stronger acid releases a weaker acid.
BaSO4 + 2HCl = H2SO4 + BaCl2 is not possible as a weaker acid is releasing a stronger acid.
