Ayanna Norman · Answer 1

The Ph of a solution with (H3O+) = 5.9 x10 ^-3M is calculated as below

Ph = - Log (H3O+) concentration

that is Ph = - Log (5.9 x10^-3) = 2.2

the solution is acidic since the Ph is less than 7

Lesly Adams · Answer 2

PH is related to [H₃O⁺] as follow,

pH = - log [H₃O⁺]

As,

[H₃O⁺] = 5.9 * 10⁻³

Putting this value in above equation,

pH = - log (5.9 * 10⁻³)

pH = 2.23

Result:

As the pH of given concentration of H₃O⁺ ions is less than 7, so it is acidic in nature.
