Strong vs Weak Acids (6C.19)

Postby Chris Tai 1B » Wed Dec 04, 2019 1:06 pm

Decide which acid in each of the following pairs is the stronger and explain why: (a) HF or HCl; (b) HClO or HClO2; (c) HBrO2 or HClO2; (d) HClO4 or H3PO4; (e) HNO3 or HNO2; (f) H2CO3 or H2GeO3.

Could someone provide brief justifications for which acid is stronger in each example?

Look at which ones have the higher electronegativity difference on a central atom and which ones have more oxygens attached to the central atom.

To consider the strength of an acid/base, consider two things:
1. The relative strength of the bonds - typically, the stronger the bond, the weaker the acid/base

2. The strength of the resulting anion - consider resonance and electronegativity.
