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."

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.
