Ph of 1m hf
WebbA solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
