HF will dissociate the most/least in which of the following solutions
a) 0.1M NaF b)0.2M NaF c)0.1M CaF2(it is soluble) d) 0.1 M Hcl e) 0.1 M NaOH
It will be dissociated most in the presence of stron base as it removes all H+ ions from equilibrium and shifts it more on the right side.
HF (aq) <---> H+(aq) + F- (aq)
It will be least dissociated with highest concentration of common ion H+ or F-
0.2M NaF and 0.1M CaF2
