Question

Rank the followig compounds in order of decreasing acid strength using periodic trends. Put them strongest to weakest: H2S, HCl, BH3, HBr.

Match the follwing acids to the given Kal values: H2S, H2SO4, H2SO3

Kal= 1.7*10^-7

Kal= 1.7*10^-2

Kal= very large

Answer 1

Answer #1

PART-1

Stongest to weakest

HI HCl H2S H2O

--------------------------------------------------------------------

PART-B

H2SO4 = Ka1 - very large

H2SO3 - 1.7*10^-2

H2S = 1.7*10^-7
