Answer 1

Solution - b Naf » Httf Nattf hf feebly dissociated - naon walton - oi that strongly dissonalia ly acidie solution wat will be more soluble. but Na Br wat toi Natton wat ton HT t Bi - nt a Br no effect of PM en Na for solubility ii) Ba(com)2 , Balele), Balloy), Batr +24ore Bate will not react with or while dori will not react with HT
