Relation between normality and molarity

Normality and Molarity are related as:

For acids

Normality = Molarity x Basicity

where basicity is the number of H+ ions a molecule of an acid can give.

For bases

Normality = Molarity x Acidity

where acidity is the number of OH- ions a molecule of a base can give.

Thank u it really helped me a lot

Or
Normality = molarity x valency factor

I really want exactly what is the significance of normality. On which context normalty can be used, not the formula. Can you please tell me?

THANK U . IT'S REALLY HELPFUL BUT I NEED AN ANSWER FOR MY QUESTION


MY QUESTION IS


K*1000/ NORMALITY / K*1000 / MOLARITY

THANK YOU

Thank U sir

So,its Normality=n times molarity.(n=max no.of +ve ions exchanged)

Unknown said...

Normality=molarity×n factor

Normality term having lot of importance. In redox titrations where lost of electrons and gain of electrons by the oxidising agent and reducing agent is not equal, you must ho ffor the Normality term. In case of H2SO4 two replaceable H+ ions present but when we titrate it against NaOH, contains only one OH- ion. So in the above situation you must use Normality term. Which makes both terms equal for Calaculatons and also for practical purposes also.
