The substance is a base option (E) 8.3; basic is correct because pH value is greater than 7.
What is pH value?
The pH of a solution is a measurement of the concentration of hydrogen ions in the solution, as well as its acidity or alkalinity. Normally, the pH scale ranges from 0 to 14.
We have:
Hydronium ion concentration of 5.4 x 10⁻⁹
We can find the pH value:
pH = -log[H3O+]
pH = -log[5.4×10⁻⁹]
pH = 8.26 ≈ 8.3
As the pH value is greater than 7
The substance is basic
Thus, the substance is a base option (E) 8.3; basic is correct because pH value is greater than 7.
