Answer to Question #114491 in General Chemistry for Lillian

Question

The hydronium content of a popular soft drink is measured and found to be 5.63×10⁻³ M. What is the pH of this soft drink?

Answer 1

Solution:

[H₃O⁺] = 5.63×10^-3 M

The pH is calculated using the expression:

pH = - log[H₃O+]

pH = - log(5.63×10^-3) = 2.2495 = 2.25

pH = 2.25

Answer: The pH of this soft drink is 2.25
