Question

Which has higher concentration of H+ ions and why
HCl
CH3COOH
H2SO4
H2CO3

The weak acid will dissociate less and hence will give less H+ ions

and stronger acids have an higher degree of dissociation which means more H+ ions

The weak acids among the list are: CH3COOH

Whereas Strong acids are: HCL , H2SO4 , H2CO3
