The ph of a fruit juice is 3.2. find the hydronium ion​ concentration, left bracket upper h 3 upper o superscript plus right bra
melomori [17]

pH is referred to as the scale to describe the hydronium ion concentration of a

solution. It is used to measure the acidity or basicity of a solution. pH of an acidic solution is less than 7, a neutral solution is 7, and a basic solution is greater than 7.

pH can be calculated using the formula:

pH = - log [H_{3}O^{+}]

Given the pH of solution is 3.2.

Finding out the concentration of hydronium ion from pH.

pH = - log[H_{3}O^{+}]

3.2 = - log [H_{3}O^{+}]

[H_{3}O^{+}] = 10^{-3.2}

[H_{3}O^{+}] =   6.3 * 10^{-4} M

Therefore, the hydronium ion concetration of the solution is 6.3 * 10^{-4} M
