Solution A has 10 times more hydrogen ions than solution B.. The correct option is B.
<h3>What is a pH?</h3>
pH is the potential of hydrogen ions, or measure of hydrogen ion concentration.
It is generally used to determine the acidity and basicity of the solution based on pH scale.
The pH scale is logarithmic, which means that each pH unit contains ten times the number of hydrogen ions as the unit above it. So solution A has 10 times more hydrogen ions than solution B.
Thus, the correct option is B.
