Acid Nomenclature


Exciting fascinating chemistry we're, beginning to look at acid bases in order to do acid bases we're going to start with acidomalation. Now, the first type of acid nomenclature is binary, which only meets two the first element of any acid is always hydrogen, and then some non-metal of nitrogen fluorine carbon bromine anything on those lines all right. So what we do is we take hydro, acid base words. So an example, if it was HCL, it'd be hydro, that's chloride.

So it'll, be caloric acid. And we get. Hydrochloric acid now for eight to the polyatomic, eight, ice acid. So here we have, the example, hno3 no3 is nitrate take the aid off and place it with ice. And we get nitric acid. All right last ones it acids. ISO acids are going to be us acids.

So right here clo2 is chlorite h out front identifies as an acid. So take the ite off and place it with us, and it's chorus acid, all right so distinction with the strong and weak acids, all right for a strong acid we're going to make an assumption what that means. Is it dissociates 100 percent? What does that mean? Dissociate means it breaks down into its base ions. It dissolves, it separates into its base science. Now, a weak acid goes through equilibrium.

So like chorus acid, which is a weak acid we're going to have both hydrogen ion chloride ion and the acid at the end of the day when a strong acid like hydrochloric acid is 100 dissociated. We have no acid at the end, just the ions there. So how do we distinguish between strong and weak? Well, we're. Going to make an assumption that all binaries are strong. So if it's HCL hf, hi h2s, all those are going to be strong for eights and nights. What we do is we take the number of oxygen subtract.

The number of hydrogens that number is greater than or equal to two, and it's strong, less than two it's. Weak. So let's do the example h2so4, which is sulfate, which means a sulfuric acid all right? So we take the number of oxygen, four minus another hydrogen's, two that's equal to two, so it's, definitely greater than. Equal to so that's, a strong acid, all right, let's do example of h2co3 co3 is carbon eight.

So that mean, ice so that's, a carbonic acid, carbonic acid, taking number of oxygen is three minus hydrogen's, two that's less than two. So that's a weak acid. All right so let's do these we'll do these in class h, I h3 bf3, hio2, we'll name them, identify the stronger, weak and then hydrocyanic acid, hydrofluoric, acid and carbonic acid. We'll do the formulas on those.

And then the strongest week as well, all. Right and then we'll do these in class as well, that's, it takes care be good any questions. Let me know you.
