A solution with pH of 3 is one with a Hydrogen ion (H+) concentration of 0.001 mol dm-3.
An example would be a 0.001 mol dm-3 Hydrochloric Acid (HCl) solution, because HCl is a strong acid which fully dissociates to H+ and Cl- ions in solution.
However, most acids could be made into a solution of pH 3 at appropriate concentrations.
A substance with a pH of 3 is considered to be acidic. Examples of substances with a pH of 3 include lemon juice and vinegar.
Apples have a pH level of 3. Also, soda has a pH level of 4, and vinegar's pH level is 2.5.
pH of 3 is acidic. If pH =7, then the substance is neutral, If pH<7 subs. is acidic, If pH>7 subs. is basic. The extent of acidic and basic nature increases or decreases as you move towards 0 and 14 respectively.
To determine the pH of a substance using the pH method, you will need a pH meter or pH strips. For a pH meter, simply immerse the electrode into the substance and wait for the reading to stabilize. For pH strips, dip the strip into the substance and compare the color change to the provided chart to determine the pH value.
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.

The substance with the highest pH is liquid ammonia, which has a pH of about 11.6.
pH of 3 is acidic. If pH =7, then the substance is neutral, If pH<7 subs. is acidic, If pH>7 subs. is basic. The extent of acidic and basic nature increases or decreases as you move towards 0 and 14 respectively.

The substance with a pH of 13 is strongly basic. Substances with pH values greater than 7 are considered basic, and the higher the pH value, the stronger the basic nature of the substance.
Substances with a pH level of below 7 are said to be acidic and substances above the pH level of 7 are alkaline. An example of a substance with the pH of about 3 is orange juice.
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
These words are: acidic, neutral, basic.
Strong acids have pH values below 3 , so it is a weak acid.
PH scale is a scale that shows the substance is PH ....... Example: The substance is PH 7, so it is neutral The substance is PH 3, so it is acid The substance is PH 10, so it is alkali
