Question

Which [H+]

[H+] concentration describes the most acidic solution?
○ 10-¹
10-14
010-7
10-5

Answer 1

The [H+] concentration that describes the most acidic solution is 10^-5. The lower the pH value, the higher the [H+] concentration and the more acidic the solution. The pH value of a solution is defined as the negative logarithm (base 10) of the [H+] concentration. Therefore, a solution with a pH value of 5 has a [H+] concentration of 10^-5.
