What the correct answer?
alexandr402 [8]

B. Bleach and sea water should be identified as bases

Explanation:

  • The pH scale measures the acidic or basic nature of a substance.
  • Ranges from 0 to 14.
  • If pH is lower than 7 → the solution is an acid.
  • If pH is more than 7 → the solution is an basic or alkaline.
  • If a pH is a 7 it is neutral.

In the given question, the pH scale measures for bleach is 8 and for sea water it is 13. So, bleach is basic, not neutral and Sea water is basic too instead of acid. So, Bleach and sea water should be identified as bases.
