How to determine the strength of acids?

Postby Alyssa_Hsu_2K » Sat Dec 03, 2016 11:09 pm

Determine which acid in each of the following pairs is stronger and explain why:
1. HF or HCl
2. HClO or HClO2
3. HBrO2 or HClO2
4. HClO4 or H3PO4
5. HNO3 or HNO2
6. H2CO2 or H2GeO3

Thanks!

In general, stronger acids are composed of more electronegative ions and larger ions.

Also, stronger acids will generally have a greater number of oxygens. For example in number 2- HCl02 will be a stronger acid than HClO.

In an acid with 2 atoms, the one with a larger atomic radius is more acidic, since it is easier for them to give away that Hydrogen. Also, in acids with more than 2 atoms, look for the one with more Electronegative groups. In general, look for the acid that can give up that H+ easier. Those are more acidic.
