Question

How does the strength of an acid relate to pH?

Answer 1

Hint : To know the relation between the strength or the concentration of an acid with the pH, we should go through the pH scale value for all types of substances. As the strength of an acid is inversely proportional to the pH value.

Complete Step By Step Answer:
The strength of an acid is proportional to its ionization and pH decreasement.
As the pH diminishes, the acidity is greater.
When the pH increases, the acidity is lesser. Thus, the basicity increases.
The pH of an acid solution changes with concentration of the acid. The concentration of the acid affects the concentration of hydrogen ions produced. For example: pH values can be used to compare the acid strength of different acids. All the acids to be compared must be of the same concentration.
The pH scale ranges from 0 to 14 with 7 being neutral, less than 7 being acidic, and greater than 7 being basic. Any number less than seven on the pH scale is considered an acid.
This is related to the degree of being an acid (strong or weak acid) pH. pH is a scale which can be used to measure the acidity or basicity in a solution. The scale has numbers from 1 to 14. pH 7 is considered as a neutral value. Pure water is said to be having pH 7. In the pH scale, from 1-6 acids are represented.

Note :
All acids and bases do not ionize or dissociate to the same extent. This leads to the statement that acids and bases are not all of equal strength in producing ${H^ + }$ and $O{H^ - }$ ions in solution. The terms "strong" and "weak" give an indication of the strength of an acid or base.
