Question

Solution A has HCI dissolved with a H value of 5. Solution B also has HCI dissolved, but has a pH value of 4. Which of the following makes a valid comparison of the solutions? A.Solution A is more acidic than solution B. B. Solution B contains twice as much HCI as solution A. C. Solution B contains ten times more HCI than solution A.

Answer 1

solution of A P^H = 5

[ H⁺ ] = 10^-5

solution of B P^H = 4

[ H⁺  ] = 10^-4.

Lower P^H value have high acidic character .

from above relation

solution B [ H⁺ ] = 10 times of solution of A of its H + ion concentration.

ANSWER = C solution B contains gten times more HCL than solution A.
