In chemistry, the pH of a solution is a measure of the acidity or alkalinity of a solution. Water has a pH of 7 and, in general, acids have a pH less than 7 and alkaline
solutions have a pH greater than 7. Find the pH of a solution with a hydronium ion concentration of 8.3 x 10-6 moles/liter. Round your answer to two decimal places,
if necessary

Sagot :

[tex]pH = 5.08[/tex]

Step-by-step explanation:

The pH of a solution can be calculated from its hydronium concentration using the equation below:

[tex]pH = -\log [H_3O^+][/tex]

where [tex][H_3O^+][/tex] is the hydronium ion concentration in mol/liter unit. This notation is the same as the more familiar symbol [tex][H^+][/tex] for hydrogen ion concentration. Since the hydronium ion concentration is [tex]8.3×10^{-6}\:\text{mol/L},[/tex] the pH value of the solution is

[tex]pH = -\log (8.3×10^{-6}) = -(5.08) = 5.08[/tex]

This means that the solution is acidic since its pH value is below 7.
