Is there something with a pH level lower than 2?

Yes, the pH scale traditionally ranges from 1-14. However it is possible to acheive solutions/substances that have a pH below zero. Hydrochloric acid has a pH of around 1.


What has a pH of 0-6?

Substances with a pH of 0-6 are considered acidic. Examples include lemon juice, vinegar, and stomach acid.

Are all substances either acidic or basic?

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.


What are the differences between pH levels in alkaline and acidic substances?

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.


Why do some substances with high pH burn your skin while substances of similar pH do not burn your skin?

The pH is not the only risk factor of a substance.


How does pH enter freshwater?

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.


What is the midpoint of the pH scale?

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.


How do certain substances affect the pH level of tap water?

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.


What is a Substances with a pH greater than 7 is describes as?

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).


Can an aqueous solution have a pH of zero?

No. pH is a log scale. You can't have a pH of zero. ---- Above answer left in to correct a misconception. Yes, you certainly can have a pH of zero. A 1 molar solution of a strong acid has a pH of zero, and stock HCl (roughly 12 molar) has a pH of about -1.1 or so. pH is the negative log of the hydrogen/hydronium ion concentration, which for a strong acid is approximately the same as the acid concentration. The log of 1 is zero, therefore the pH of a 1 molar solution of a strong acid is zero. The log of 10 is 1, therefore the pH of a 10 molar solution of a strong acid is -1.


Why are acidic substances lower in pH value than basic substances?

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.
