Ph tells you how acidic/basic a solution is. It is a measure of the relative concentrations of H+ ions to OH- ions.
The main difference between pH levels in alkaline and acidic substances is that alkaline substances have pH levels above 7, while acidic substances have pH levels below 7. Alkaline substances are basic and can neutralize acids, while acidic substances can corrode materials and cause irritation. pH levels indicate the concentration of hydrogen ions in a substance, with lower pH levels indicating higher acidity and higher pH levels indicating higher alkalinity.
No, not all substances are either acidic or basic. Some substances are neutral, meaning they have a pH of 7. Acidic substances have a pH below 7, basic substances have a pH above 7, and neutral substances have a pH of 7.
A substance with a pH greater than 7 is described as basic or alkaline. These substances have a lower concentration of hydrogen ions compared to substances with a pH below 7 (which are acidic).
Strong acids at a concentration of 1N.
The pH scale ranges from acids to alkali's. The strongest acid is red then it gets lighter, (orange, pale, yellow) then it goes to green (neutral) and alkali's are more dark greenish purple colours. Hope this helped. :)
substances of ph
Substances are described as 'Acidic' if their pH < 7 Substances are described as 'Basic' if their pH > 7 Substances with a pH = 7 are described as neutral(a chemical salt). There is no such descriprtion as 'Acidic Basic'. They are contradictory!!!!

The pH is not the only risk factor of a substance.
Water will always have a pH. pH is a measure of how acidic or basic a solution is. Intruduction of basic substances such as carbonates will raise pH. Introduction of acidic substances such as carbonic or sulfuric acid will lower pH.
The midpoint of the pH scale is pH 7, which is considered neutral. Substances with a pH lower than 7 are acidic, while substances with a pH higher than 7 are basic.
Substances like acids (e.g. lemon juice) can lower the pH level of tap water, making it more acidic. Conversely, substances like baking soda can raise the pH level of tap water, making it more alkaline. The pH level of tap water can be altered by adding these substances in small quantities.

Acidic substances have higher concentrations of hydrogen ions (H+) which results in a lower pH value compared to basic (alkaline) substances. A lower pH value indicates a higher concentration of H+ ions, while a higher pH value indicates a higher concentration of hydroxide ions (OH-) found in basic substances.
No, a higher pH does not necessarily mean a substance is safer. Some high pH substances can still be harmful, while some low pH substances can be safe. pH is just one factor to consider when evaluating the safety of a substance.
