Question

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.

Answer 1

pH = -log[H₃O⁺]
= -log(3.5×10⁻⁴)
= 3.46

Hence the pH of the given agricultural product is 3.46 which means the product is acidic.

If the pH > 7, then the solution is basic.
If the pH < 7, then the solution is acidic.
If the pH = 7, then solution is neutral.

Answer 2

The pH of the given agricultural product = 3.456

Step-by-step 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
