Question

Which of the following conditions is acidic?


Select one:
A. [OH-] = 8.3 x 10-5 M
B. [H3O+] = 7.2 x 10-3 M
C. [OH-] = 1.0 x 10-7 M
D. [H3O+] = 1.4 x 10-11 M

Answer 1

Answer:

b. h3o+ 7.2× 10^-3 is acidic

Answer 2

Answer:

[H3O+] = 7.2 x 10-3 M condition is a acidic. So the correct option is B. [H3O+] = 7.2 x 10-3 M

Explanation:

Water becomes H3O+, an acid when it functions as a base. This is known as the conjugate acid of water. An acidic environment is defined as a zone or enclosure with a pH reading of less than 7.0. The lower the pH, the more acidic the solution, which also means a higher concentration of hydrogen ions and a faster rate of corrosion.

Thus, the magnitude of an ionization reaction's equilibrium constant can be used to calculate the relative strengths of acids and bases.
