On the metric scale, they would be units like meter, liter, gram and second. If you have the stairs it looks like this:
_K__
_H__
_D__
__BASE__
Meter (m)
Gram (g)
Liter (l)
Second (s)
__d__
__c__
__m__
The other units (not under the BASE) are called derived units. K is kilo, H is hecto, D (or da) is deka, d is deci, c is centi, and m is mili. You can add base units to these
Ex.
Kilograms

A practical definition might include:
they taste bitter
are good electrolytes in solution (assuming you have a soluble base)
change the colour of indicators
feel slippery
a more technical definition might include either or both of these definitions:
bronsted lowry: they are proton acceptors (a proton is a hydrogen atom lacking an electron)
lewis: they are electron pair donors (electrons are generally found in pairs around an atom)
Either the opposite of an acid (on the higher end of the pH scale), or the base of an exponent (the number being squared or cubed).
According to the general definition, base is any substance which gives OH- ions in water.

kb is the Dissociation Constant for Bases.
phenolphthalein
Benzodiazepines are products of organic chemistry.
everything is made of elements and chemistry is basically the study of chemicals
Correct chemistry is a chemistry made with scientific methods, that affect as little as possible the environment and health, which improves people's lives.
kb is the Dissociation Constant for Bases.
"Salt" in chemistry is any compound made up of a metal and a non-metal, like Zinc sulfide or sodium chloride. Acids and bases is a little different subject.
neutralization, ion formation, displacement...

alkalies are bases which are solid substance that dissolve in water to form alkalies (liquid)
Bases are very important in the branch of organic chemistry. They are responsible for releasing ions into various medium which lead to any reaction.

scope of physical chemistry is very huge it includes rate of rections;acids bases; buffers; ph; quality and control etc
