The correct answer is B)
.The pH of a solution is a measure of the concentration of hydrogen ions
in the solution. The pH scale ranges from 0 to 14, with 7 being neutral. A pH less than 7 indicates an acidic solution, while a pH greater than 7 indicates a basic solution.In this case, the solution has a pH of 10, which means it is a basic solution. The concentration of hydrogen ions
can be calculated using the formula:
Rearranging the formula, we can find the concentration of hydrogen ions:
Substituting the given pH value of 10, we have:
Therefore, the concentration of hydrogen ions
in the solution is
.
