What is the chemical formula for an acid?worth 10 [points?
Answer:
I'm not sure whether you are just looking for an example of an acid, or if you want to know a general formula for any acid.
If you want to know formulas for specific acids, this is easy enough--- there are seven strong acids, and they are HCl, HBr, HI, H2SO4, HNO3, HClO4, and HClO3.
If you want a general formula for any acid, I'm afraid there is none. It is true that a large number of acids have an "H" at the beginning because the H+ ion causes acidity (like the examples above). But by some definitions of "acid", there does not actually need to be an H+ ion. For example, CO2 is an acidic substance because the carbon atom reacts with electron donors to neutralize them, but it has no hydrogen (this uses the Lewis definition of acidity). So there is no way to create a general formula for acids, you simply have to know the properties of the molecule.
Here is a good one. C20H25N3O
An acid always has a h+ ion
for ex.
HCl-hydrochloric acid
so basicly u are looking for a H in the formula and a (aq) aqueous
An acid is usually in the form HA, where H is hydrogen and A is the conjugate base. Here's some examples:
H2SO4 = sulfuric acid
HCl = hydrochloric acid
HCH3COO = acetic acid
HNO3 = nitric acid
H2CO3 = carbonic acid
HF = hydrofluoric acid
its HX (H+X-); where H+ is the hydrogen and X- is the conjugate base.
