Anything with an empty orbital... the hydrogen ion is the most common example. BH3 is the typical example, but any metal in a coordination complex can be considered a Lewis acid.

which of HF and HI is more acidic
Sahr Reply
HF is
HF
Duku
HI is stronger than HF (greater size of I courses greater length of bond)
galina
HI is a stronger acid due to less efficient orbital overlap. HF will react with with glass and extract calcium from bones, but those hazards are not because it's a stronger acid, but because it contains fluorine.
