Answer:
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
