Acids
- Form Hydrogen ions when dissolved in water
- Have PH values below 7
- Increased hydrogen ions (H+)
- Lituns turns red
- Ex. Vinegar and Lemon
Bases
- Reduce the concentration of hydrogen ions in a solution
- PH values above 7
- Forms hydrogen (OH-)
- Litnus turns blue
- Ex. Antiacid, Hand Soap, and Ammonia
Both
- Hydrogen ions
- Not Neutral
- Water Based

What else can I help you with?
Do bases have a sharp or sour taste?
Bases have a bitter taste, not a sharp or sour taste. This is in contrast to acids, which typically have a sour taste.
Do bases tastes bitter or acids?
Acids taste bitter.
Do bases have a high or low concentration of hydrogen ions?
Bases have a lower concentration of hydrogen ions compared to acids. This is because bases donate hydroxide ions (OH-) which can combine with hydrogen ions (H+) to form water, reducing the concentration of free hydrogen ions in the solution.
Why are bases sometimes describes as the opposite of acids?
Bases are the opposite of acids due to the fact they are a hydrogen ion acceptor and an acid is a hydrogen ion donor. In the many definitions of bases and acids, bases do the opposite of what acids do. -- In the Lewis definition, acids are electron pair acceptors while bases are electron pair donors. -- In the Bronsted-Lowry definition, acids are substances that donate protons while bases are substances that accepts protons. -- In practicality, acids lower the pH of a solution and bases increase the pH of a solution.
Compare and contrast an acid to a base?
Acids are substances that release hydrogen ions (H+) in solution and have a pH below 7, while bases are substances that release hydroxide ions (OH-) in solution and have a pH above 7. Acids tend to taste sour, react with metals to produce hydrogen gas, and turn blue litmus paper red. Bases, on the other hand, tend to taste bitter, feel slippery, and turn red litmus paper blue.
Compare and contrast the preparation of a salt from an alkali and a base?
Bases are substances that react with acids and neutralize them. They are usually metal oxides, metal hydroxides, metal carbonates or metal hydrogen carbonates. Many bases are insoluble - they do not dissolve in water.If a base does dissolve in water, we call it an alkali.
How would you compare acids and bases in terms of their pH?
acid pH < 7base pH > 7
