The aqueous solution of an acid HX has the highest pH, the HX is-
HF
HCl
HBr
HI
As we learnt
pH of solution -
HF > HCl > HBr > HI
Decreases down the group
HF is a weak acid. So its an aqueous solution that has high pH.
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
