Strong Acids

Postby Johnathan Smith 1D » Sun Dec 01, 2019 8:47 pm

Okay I know strong acids lose the hydrogen ions easily but what exactly does that mean?

This has to do with the bond length as the longer the bond, the more easily it is broken. This means that if the bond is longer, then it would be considered a stronger acid in comparisons such as HF and HI as in this case HI bond is longer making it easier to lose the H+.

How do you tell if it has a longer bond to the H?

Strong acids contain longer bonds that are more easily broken, causing H+ ions to be more readily emitted. For instance, the bond in HI is longer than that of HF since Fluorine is more electronegative than Iodine. As a result, HI is more acidic than HF.

Look at the electronegativities of the atoms involved to determine bond length. More electronegative atoms will form shorter, stronger bonds with the hydrogen, and less electronegative atoms will form longer, weaker bonds with the hydrogen.

That makes sense!! does the size of the atom also play a role? or do you just look at electronegativity?
