Vibrissae, more commonly known as whiskers, are sensory hair that generally have a tactile sense, which is equivalent to skin. They grow on most mammals except monotremes (duck-billed platypus and echidnas) and humans, though humans still have remnants of the muscles once associated with vibrissae in their upper lips. Vibrissae serve a number of purposes: such as sense of touch; detection of danger, air and water currents, and movements of other animals; and the locating of food.

The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration

Hitman42 [59]

Answer:

The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.

Explanation:

The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.

A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.
