Whats the difference between an acid and a base?

Answer 1

In simplest terms, an acid produces hydrogen ions (H+) when mixed with water while a base produces hydroxide ions (OH-). Acids have more hydrogen ions and there pH is 0-7, bases have less hydrogen ions so there pH is 7-14. Acids are substances that donate protons (hydrogen ions, H+) to bases. Bases are substances that accept protons from acids.

Answer 2

In simplest terms, when dissolved in water and acid will produce hydrogen ions (H+) while a base will produce hydroxide ions (OH-).
Acids have a pH less than 7 and bases have a pH higher than 7
Concerning pH, an acid is a substance with a pH below 7, and a base is a substance with a pH above 7.

Acid: is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0 in its standard state.

Base: A base in chemistry is a substance that can accept hydrogen ions or more generally, donate electron pairs.
the difference is the pH paper. if the pH paper is dipped into an acid, the pH scale would show 1-6, if dipped and neutral, 7, if dipped and 8-15, base
The difference between base and acid is that:

• - Bases have pH more than 7
• - Acids have pH less than 7
• - Bases turn litmus paper blue
• - Acids turn litmus paper red
• - Bases taste Bitter like 'soap' or 'bleach'
• - Acids taste sour like 'fruit juice' or 'vinegar'

Answer 3

Acids release hydrogen ions (H+) in a solution, lowering the pH below 7, while bases release hydroxide ions (OH-) and raise the pH above 7. Acids taste sour, react with metals, and turn blue litmus paper red. Bases taste bitter, feel slippery, and turn red litmus paper blue.
