Answer:
The solution is basic.
Step-by-step explanation:
Applying,
pH = -log(H⁺)................. Equation 1
From the question,
Given: (H⁺) = 2.7×10⁻⁹ M
substitute these value into equation 1
pH = -log(2.7×10⁻⁹)
pH = 8.57 M.
pH scale
For acidity = 0-6
For neutrality = 7
For basicity = 8-14
From the above calculation,
The solution is basic.
