What is the word for how polyprotic an acid is?

What is the word to describe the number of acidic hydrogens an acid has? I am currently thinking something like "proticity", but I am not sure The use case world be for a table of things like this:



```
Acid    | Proticity
--------------------
CH₃COOH |  1
H₂SO₄   |  2
H₃BO₃   |  3

```

Or in a set of statements like this:



> 
> The volume of gas produced by reaction A was 4.6 L. The proticity of Acid B was 3. The tare mass of object C was 4.76 g. The density of substance D was 7.8 g/mL.
> 
> 
> 


Is there a specific word used to refer to this quantity? What word should I use to refer to it? 




The term that I learned was (ironically) "[basicity](https://answers.yahoo.com/question/index?qid=20081224234255AAJxP4y)."


I'm not sure if that's the standard term, or even if there is a standard term, but this refers to how many bases you need to neutralize the acid completely.


EDIT: Thanks for the correction from LDC3: the "basicity" of an acid refers to how many bases you've already added to it. Thus, $\ce{NaH2PO4}$ would be "sodium phosphate, monobasic," $\ce{Na2HPO4}$ would be "sodium phosphate, dibasic," and so on.


Again, not sure if this is standard terminology.

*Proticity* does sound nice, but it is a bad choice since the term has already been introduced by *Peter D. Mitchell* (1978 Nobel Prize in Chemistry) in a completely different context.


In his [Nobel Lecture](http://www.nobelprize.org/nobel_prizes/chemistry/laureates/1978/mitchell-lecture.pdf), Peter D. Mitchell explains: 



> 
> I use the word proticity for the force and flow of
>  the proton current by analogy with the word electricity, which describes
>  the force and flow of an electron current. 
> 
>

Monoprotic, [Diprotic](http://en.wikipedia.org/wiki/Diprotic_acid), Trioprotic, tetraprotic, pentaprotic, hexaprotic, septaprotic, octaprotic....


{edit}


I then suggest "[equivalents factor](http://en.wikipedia.org/wiki/Equivalent_concentration)," which is directly related to the concept of normality:


"Normality isn't the same like Molarity, but you can say N = M \* equivalents. 1 M HCl = 1 N HCl, but 1 M H2SO4 = 2 N H2SO4..." -[source](http://www.sciencemadness.org/talk/viewthread.php?tid=3798)
