What is the difference between an organic acid and an Inorganic acid?

What is the difference between an organic acid and an Inorganic acid?

(OP)
I am looking for coatings resistant to acids and have found many for inorganic acids, but only a few for organic acids.
This may be a basic question but what is the difference between organic and inorganic acids? Why is one more corrosive?

cdcosta (Chemical):

Isn't this basic high school chemistry and normally found in search engines such as Google, etc.?   Certainly, the corrosion of one type versus the other depends on the parent metal or material you are planning to attack or protect.

RE: What is the difference between an organic acid and an Inorganic acid?

Regarding your first statement, one factor could be that inorganic acids represent by far a much larger volume chemical commodity produced, when compared with organic acids.
As for the second, I suggest you read appropriate chemistry books on acids' chemical activity and corrosion.

RE: What is the difference between an organic acid and an Inorganic acid?

The basic difference between "organic" and "inorganic" acids its the presence of the carbonile function, which means presence of a C atom in the molecule.

Usually the "organic acids" are weaker than the "inorganic ones", but after all, its relative to operating conditions, active surface, etc.

I don't know which kind of coatings you're seaching for, but some times this substances are made from organic groups that -like amines, for instance- may react with weak acids and create a "hot spot" for corrosion.
