Question

Describe how you could show that phosphorus acid, H3 PO3 , is a weaker acid than hydrochloric acid.​

Answer 1

Answer:

It is because acidity increases on moving across a period in the periodic table as electronegativity increases on moving across a period in the periodic table as atoms become smaller.

increased electronegativity causes the bond between Hydrogen and the atom to grow weak allowing for faster dissociation

Therefore HCl is stonger than phosphorus acid .
