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.
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
Well coca cola has a pH of about 3, drink that and see what happens.
If a substance has a PH of 11 then the substance is basic.
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.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic

If a substance has a PH of 11 then the substance is basic.
This is the citric acid.
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.
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.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
Alkali isn't an acid. Alkali and acid are terms used when the pH of a substance is a certain number, for example if a substance has a pH of 1, 2, 3, 4, or 5, then the substance is an acid. If the pH is 11, 12, 13, 14 or 15, then the substance is an alkali.
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
The pH scale ranges from 0-14 pH. A substance that has a pH of 7 is considered to be "neutral," like pure water. A substance that has a pH less than 7 is said to be acidic, and a substance that has a pH greater than 7 is said to be basic. Therefore, the difference between those two pH levels is that the 4 pH substance is more acidic and the 10 pH substance is more basic. The more basic or acidic, the more caustic and/or corrosive the substance will be.
Strong acids have pH values below 3 , so it is a weak acid.
