Huey · Answer 1

PH = 4.2

[H+] = 10 ^ - pH

[H+] = 10 ^ - 4.2

[H+] = 0.00006 M

Answer D

Irwin · Answer 2

The pH of a solution is related to the hydrogen ion concentration in a logarithmic function which is expressed as:

pH = - log[H+]

4.2 = - log [H+]

[H+] = 6.31 x 10^-5 M

Therefore, the correct answer from the choices listed above is option D, 0.00006 M.
