Question

Given the following hydrogen ion concentration, determine if the solution

is acidic, basic, or neutral.

[H*] is 2.7 x 10-9 M

Answer 1

The solution is basic.

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.
