human blood has an approximate ph of 7.3. which substance is more basic than human blood?\n\na. a water and ammonia solution with a ph of 11\nb. grape juice with a ph of 4.5\nc. apple juice with a ph of 3.0\nd. a human stomachs digestive juices with a ph of 2

Answer

Explanation:

Step1: Recall pH - basicity relationship

A higher pH indicates a more basic solution.

Step2: Compare pH values

Human blood has pH = 7.3. We compare with each option:

  • Option A: pH = 11, 11>7.3
  • Option B: pH = 4.5, 4.5<7.3
  • Option C: pH = 3.0, 3.0<7.3
  • Option D: pH = 2, 2<7.3

Answer:

A. A water and ammonia solution with a pH of 11
