Solution A has a pH of 5, and Solution B has a pH of 6.
Leto [7]

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.

based on your observation, you suggest that the presence of water could accelerate the growth of bread mold
Marta_Voda [28]
Molds and fungi are found everywhere inside and outside, and can grow on almost any substance when moisture is present. Molds when they reproduce make spores, which can be carried by air currents. When these spores land on a moist surface that is suitable for life, they begin to grow. Molds are essential to the natural breakdown of organic materials in the environment. Mold is normally found indoors at levels that do not affect most healthy individuals. When these levels become abnormally high as determined by indoor air quality testing or a mold inspection, remediation is recommended to be carried out by a professional remediation company.
