What's the difference between a base and an alkali?
- There is one difference: an alkali is a base that dissolves in water.
- All alkalis are bases, but not all bases are Alkalis.
Properties of Bases:
- Bases are bitter tasting.
- Bases have a pH>7.
- Bases are slippery.
- Corrosive.
- Bases can conduct electricity because they produce electrolytes when dissolved in water.
- Bases turn red litmus paper blue.
- Bases neutralize Acids.
What is the definition of a base? There are three definitions based on three theories ...
- A base dissolves in water to produce OH- ions.
- Bases are electron (OH-) pair donors.
- Bases are proton (H+) acceptors.
Real World examples of bases:
- Dish detergent contains Sodium carbonate.
- Aluminum hydroxide is found in Deodorant.
- Baking Soda contains Sodium Bicarbonate.
Let's see...What else do you need to know?...What's the difference between the strength and concentration of an base?
- The strength of a base is determined by a bases ability to completely disassociate to form OH- ions.
- The concentration of a base is the number of particles per liter.
Here is an example of a base reacting with a metal...
FUN FACT:
Baking soda can be used to fight fires by obstructing the flow of oxygen.
