The pH scale measures

Answer 1

The pH scale isn't used for measuring anything. It tells if a substance is an acid or a base. On the pH scale, 7 or more is considered a base. lower than 7, on the pH scale is considered an acid. Acids are usually sour, sweet, or have a very sweet, bitter taste. Usually Bright colors. And Bases are mostly poisons. THey have a horrible bitter taste. Some can kill you if inhaled or consumed.

Answer 2

The definition of pH is: negative logaritm of the activity of hydrogen ions from a solution.

The pH is a measure of acidity and basicity.

The conventional pH scale is between 0 and 14. The measuring instrument is called pH-meter.

Answer 3

The pH scale measures the acidity or basicity of a solution, on a scale of 0 to 14. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is basic. The scale is logarithmic, so each whole number change represents a tenfold change in acidity/basicity.

Answer 4

Measures the acidity or alkalinity of a substance. A pH of -1 to about 7 is acidic, 7 is neutral, and above 7 is alkaline.

Answer 5

The Concentration of hydronium ions in a solution

Answer 6

pH measures the hydronium ion (H3O+) concentration. This is then equated to acidity (pH<7) and alkalinity (pH >7)

Answer 7

how acidic or alkaline the liquid is
