Identifying Acids and Bases

Postby Nicole Jakiel 4F » Sun Dec 02, 2018 1:46 pm

I know that whenever there is a compound with a nitrogen that has a lone pair it can be identified as a base, but is there any characteristic like this that allows us to identify acids based on the compound's structure?

Compounds that have hydrogen atoms written separately in the formula usually indicate they are the terminal atom and most likely dissociate in water. A good example is CH3COOH. They could have written the compound as CH4COO, but writing it the former way indicates the H is attached at another location on the molecule. If you were given a Lewis structure, then you could look for spots where there is an O-H bond. O-H bonds on a molecule are more likely to interact with O-H bonds of the water molecules.

The primary feature of a Bronsted base is a weakly bound H atom that can form intermolecular bonds with water.

So is the only way you can identify an acid and a base is either through how it is written out or by receiving the actual chemical equation to see what bonds and products are created?

If you were given a chemical equation, you would also be able to figure out whether a substance was acidic or basic by checking to see if it received or donated a proton.

In a chemical equation in which acids and bases are reacting with water, you could identify an acid because their products tend to be either a hydronium ion or proton, while the products of bases are h usually hydroxide ions.
