About this tool
Normality is reaction-dependent and is calculated here as N = M × n-factor.

Frequently asked questions
Why is an n-factor required?
Normality counts reactive equivalents, so the factor depends on the specific acid–base, redox or precipitation reaction.
Can the same solution have different normalities?
Yes. Because equivalents are reaction-dependent, one molarity can correspond to different normalities in different reactions.
What is the formula?
N = M × n-factor.
Does this calculation run on a server?
No. The calculation runs locally in your browser with JavaScript.
Can I use the result directly in laboratory work?
Use it as a calculation aid and verify reagent form, purity, constants, assumptions and your laboratory SOP before operational use.
