[H₃O⁺] = 1.81.10⁻¹⁰
pH of the solution = 9,742, is a basic solution
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H ions of 10ⁿ.
The concentration of hydronium ions determines a solution's pH.
H₂O ionization reaction
2 H₂O ⇌ OH− + H₃O⁺
The water equilibrium constant (Kw) is the product of concentration
the ions:
Kw = [H₃O +] [OH-]
Kw value at 25° C = 10⁻⁴
It is known [OH-] = 5.5 × 10⁻⁵
then the concentration of H₃O⁺:
10⁻¹⁴ = [H₃O⁺]. 5.5 × 10⁻⁵
[H₃O⁺] = 10⁻¹⁴: 5.5 × 10⁻⁵
[H₃O⁺]= 1.81.10⁻¹⁰
pH - -log [H₃O⁺]
pH = - log 1.81.10⁻¹⁰
pH = 9,742
Because the pH > 7, the solution is said to be a basic solution
