If the [H+] = 0.05 M, what is the pH of the solution, and is the solution a strong acid, weak acid, strong base, or weak
base?

a. pH= 1.3, weak acid
b. pH= 12.7, weak base
c. pH-12.7 strong base
d. pH= 1.3 strong acid

Option D. pH= 1.3 strong acid

Explanation:

From the question given:

The hydrogen ion concentration [H+] = 0.05 M

pH = —Log [H+]

pH = —Log 0.05

pH = 1.3

Since the pH lies between 0 and 7, the solution is acidic. Since the pH value is low, the solution is a strong acid

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
