Explanation:
The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.
Explanation:
- A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
- Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
- The pH is then equal to minus the logarithm of the concentration value.
- Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
- The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
- Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.
Answer:
When it stands the test of time and is supported by many experiments.
Uticaria or Hives is the hallmark sign of an allergic reaction about to turn anaphylactic.... So hallmark it is only specific toward such allergic reactions.
The basic building block of a protein is called an amino acid. There are 20amino acids in the proteins you eat and in the proteins within your body, and they link together to form large protein molecules.
