A student obtains a beaker containing a solution that is determined to have a hydrogen ion
OleMash [197]

Answer:

pH = 13.1

Basic

Explanation:

Step 1: Given data

Hydrogen ion concentration ([H⁺]): 6.7 × 10⁻¹⁴ M

Step 2: Calculate the pH of the solution

We will use the definition of pH.

pH = -log [H⁺]

pH = -log 6.7 × 10⁻¹⁴ = 13.1

  • When pH < 7, the solution is acid.
  • When pH = 7, the solution is neutral.
  • When pH > 7, the solution is basic.

Since pH > 7, the solution is basic.
