Question

the (H+) of a solution with pH =8.7 is?​

Answer 1

Answer:

$[H^+]=2.0x10^{-9}M$

Explanation:

Hello!

In this case, since the pH is a direct scale of how strong is the hydrogen ion in a solution in terms of its concentration, we can mathematically define it as:

$pH=-log([H^+])$

However we need the concentration of hydrogen ions from the pH, thereby we solve for it:

$[H^+]=10^{-pH}$

Thus, the concentration of hydrogen ions turns out:

$[H^+]=10^{-8.7}=2.0x10^{-9}M$

Such pH means that the solution is basic because basic solutions have the pH between 7 and 14, whereas acidic solutions have it between 0 and 7.
