Question

Arrange the following substances in the increasing order of the basicity from the top.

• A. Human blood
• B. Milk
• C. Ammonia
• D. Seawater

Answer 1

pH of a substance gives the nature and strength of an acid or a base.
pH values of milk, human blood, seawater, and ammonia are 6, 7.35, 8.2, and 10.6 respectively. The greater the pH more the basicity. Hence the increasing order of the basicity is milk > human blood > seawater > ammonia.
