Question

The pH level of a solution measures how acidic or basic the solution is. Values between 0 and 7 are considered acidic while values between 7 and 14 are considered basic. The pH is calculated by using the equation pH=−log[H3O+]. The notation [H3O­­­+] represents the concentration of hydronium ions, which is measured in units of moles per liter, M.
What is the pH level of a solution if [H3O+]=3.4×10^−3M?

Answer 1

Answer:

  about 2.47

Step-by-step explanation:

Your calculator will tell you ...

  $-\log{(3.4\times 10^{-3})}\approx 2.4685\approx\bf{2.47}$
