Determine the ph of an hf solution of each of the following concentrations? determine the ph of an hf solution of each of the following concentrations? 2. 5.10×10^−2 m

Respuesta :

the formula for the pH = -log [H+]
where [H+] is the molar concentration of H+ in the HF solution.
so HF --> H+ + F-
[H+] = 5.10 x 10^-2 mol HF ( 1 mol H+ / 1 mol HF)
[H+] = 5.10 x 10^-2 M H+

pH = -log (  5.10 x 10^-2 )
pH = 1.29

Answer:

previous answer is wrong
