Which solution will have the lowest pH value?

Options

  1. A0.10 M HCN
  2. B0.10 M H N O 3
  3. C0.10 M NaCl
  4. D0.10 M H 2 C O 3

Correct answer

B. 0.10 M H N O 3

Step-by-step solution

Stronger the acid, the smaller is the pH of solution. H N O 3 is the strongest acid, therefore, its solution will have lowest pH value.
