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

the correct answer is:

a. formation of precipitation

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
