Question

Which of the following is the strongest acid?

chloroacetic acid (molar mass: 94.49 g/mol; Ka = 1.4 x 10-3)

formic acid (molar mass: 46.03 g/mol; Ka = 1.8 x 10-4)

propionic acid (molar mass: 74.08 g/mol; Ka = 1.3 x 10-5)

hypoiodous acid (molar mass: 143.89 g/mol; Ka = 2.0 x 10-11)

acetic acid (molar mass: 60.05 g/mol; Ka = 1.8 x 10-5)

Answer 1

Answer #1

Ka is acid dissociation constant.

higher the Ka stronger the acid.

answer = chloroacetic acid
