Final answer:
To find the concentration of hydrogen ions ([H+]) in a solution with a pH of 10.27, use the formula [H+] = 10^-pH, yielding a concentration of 5.37 × 10^-11 M.
Step-by-step explanation:
The pH of a basic solution is 10.27, and the student is requesting the concentration of hydrogen ions, [H+].
To calculate the concentration of hydrogen ions, we use the formula:
[H+] = 10-pH
Applying the pH value given:
[H+] = 10-10.27 = 5.37 × 10-11 M
Therefore, the hydrogen ion concentration in a solution with pH 10.27 is 5.37 × 10-11 M.
