Answer 1

Answer #1

a) pH of NaF is expected to be lower than NaOH because Oh- is more basic than the F-

b)pH of h2co3 is expected to be lower than Nahco3 because h2co3 is more acidic and nahco3 is salt of its conjugate base

c) pH of H3PO4 is expected to be lower than Ca(OH)2 because H3PO4 is acidic and Ca(OH)2 IS BASIC
