Question

Select the correct answer. What is the hydronium (H3O+) concentration of a solution with a pH of 3.60?

Answer 1

Answer: The hydronium $(H_{3}O^{+})$ concentration of a solution with a pH of 3.60 is 0.56 M.

Explanation:

pH of a substance is the negative logarithm of concentration of hydrogen ions present in it.

It's formula is; pH = - log $[H^{+}]$

When pH of a solution is 3.60 then its hydronium or hydrogen ion concentration is calculated as follows.

$pH = - log [H^{+}]\\3.6 = - log [H^{+}]\\concentration of H^{+} = antilog (-3.6)\\= 0.56$

Thus, we can conclude that the hydronium $(H_{3}O^{+})$ concentration of a solution with a pH of 3.60 is 0.56 M.
