Phosphoric acid H3PO4 has three dissociable protons with pkas 2.14 and 6.86 and 12.4 which form of the acid predominates in a solution of pH 4?

pH = 4 is about in the middle (4.7) of the values pH=pKa,1 and pH=pKa,2.
This is an indication of H2PO4- abundantly being present, because
- at pH=2.14 it is halfway forming its conjugate acid H3PO4
and
- at pH=7.21 it is halfway forming its conjugate base HPO42-

Why is phosphoric acid called a triprotic acid?
because it has three protons
Is H3PO4 a acid or base?
H3PO4, also known as phosphoric acid, is an acid. It's a triprotic acid, meaning it can donate three protons in a solution. Its acidic nature is evident in its ability to release hydrogen ions (H⁺) in water, making it a crucial component in various industries and as a flavoring agent in food and beverages. As an acid, it plays a significant role in buffering systems and chemical reactions due to its acidic properties.
What do acids do in a solution'?
Basically, donate protons to the solution. H +
What is a solution that contains an excess of protons?
The solution is an acid. If it is in water (supposedly meant by questioneer), the pH value is below 7.0, so it is an acid solution: more H+ than OH-.
Why does the pH of a fatty solution decrease as enzymatic hydrolysis increases?
During enzymatic cleavage, hydrogen atoms/protons are released into the solution causing the pH to drop to build up of protons.

Protons are present in nucleus so how current flow with these particles as conventional current?
Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).

What happens if a solution changes from ph5 to ph6?
The solution is becoming more neutral so there are less free protons in the solution.
Do protons float areound in solution as tiny positive charge?
no.
Why does the pH of a fatty solution decrease as enzymatic hydrolysis increases?
During enzymatic cleavage, hydrogen atoms/protons are released into the solution causing the pH to drop to build up of protons.
What releases H plus protons in solution?
Acids release H+ in an aqueous solution.
Is NH3 a base substance?
A weak base that can accept protons in solution.
Examples of tribasic acid?
a tria basic acid is a acid containing three replacable hdrogen atoms
