The formula for the ph of a solution of hydronium ions is given by the logarithmic equation ph equals = minus −log [h3o superscript plus +], where [h3o superscript plus +] is the hydronium ion concentration. find the ph of a certain agricultural product with the hydronium ion concentration of 3.5 times 10 superscript negative 4 3.5×10−4.

The pH of the given agricultural product = 3.456

Explanation:

pH is a scale that ranges from 0 to 14, which is used for measuring the acidity or basicity of a given solution. It is equal to the negative logarithmic of hydrogen ion (H⁺) concentration in the given solution.

pH = - ㏒ [H⁺]

An acidic solution has a pH value < 7; a basic solution has a pH value > 7 and a neutral solution has pH value = 7, at room temperature.

Given: Hydrogen ion concentration [H⁺] = 3.5 × 10⁻⁴, pH = ?

To calculate the pH of the given agricultural product, we use the equation,

pH = - ㏒ [H⁺]  = - ㏒ (3.5 × 10⁻⁴)

pH = - [㏒ 3.5 - 4 ㏒ 10]

pH = - [0.544 - 4]

pH = + 3.456 ⇒ Acidic

Therefore, the given agricultural product is acidic with pH = 3.456
