Question

The pH of an acidic solution is 5.59. What is [H+]?

Answer 1

[H⁺] = 2.57x10⁻⁶ M

Step-by-step explanation:

This problem can be solved using the definition of pH:

pH = -log[H⁺]

Now we isolate [H⁺] in the equation:

-pH = log[H⁺]

`10^(-pH)`=[H⁺]

As we are given the pH by the problem, we can now proceed to calculate the [H⁺]:

[H⁺] =
`10^(-5.59)`

[H⁺] = 2.57x10⁻⁶ M

Thus, when the pH of a solution is 5,59; the molar concentration of H⁺ species is 2.57x10⁻⁶.
