The pH of carbonated drink is 3.0 what is the hydrogen ion concentration of the drink?

0.001moldm⁻³

Explanation:

Given parameters:

pH of carbonated drink = 3.0

Unknown:

Hydrogen ion concentration of the drink = ?

Solution

From the ionic product of water, the equation which relates hydrogen ion concentration and pH has been established. It is shown below:

pH = - log₁₀[H⁺]

we have been given the pH of the drink. Now let's go ahead and solve for the hydrogen ion concentration:

[H⁺] = inverse log₁₀ (-pH) = inverse log₁₀ (-3) = 0.001moldm⁻³
