What would be the H3O^+ mol/L of pop be with a pH of 3?
The pH of a solution is a measure of the concentration of hydronium ions (H3O+) in that solution. The pH scale is logarithmic, meaning that each unit change in pH represents a tenfold change in the concentration of hydronium ions.
Given that the pH of the pop is 3, we need to calculate the concentration of H3O+ ions (in mol/L).
pH = -log[H3O+]
Rearranging the equation, we have:
[H3O+] = 10^(-pH)
Substituting the given pH value:
[H3O+] = 10^(-3)
Using a calculator, we find that:
[H3O+] = 0.001 mol/L
Therefore, the H3O+ concentration in the pop would be 0.001 mol/L.
