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.

snow_tiger [21]

Answer:

The correct option is : a. diameter    

Explanation:

The Kirby–Bauer test or the disk diffusion test, is a method to determine the antibiotic sensitivity of the given bacteria. This test involves the use of antibiotic discs to determine the effect of antibiotics on the bacteria.

In this test, the wafers having antibiotics and the bacteria are placed on the agar plate and incubated. If the antibiotics present stops the growth of the bacteria, there will be an area around wafer with no bacterial growth, such an area is known as the zone of inhibition.

<u>The </u><u>diameter of this zone of inhibition</u><u> is measured to determine the </u><u>antibiotic sensitivity of the given bacteria</u><u>.</u>
