4. Determine if propanoic acid, CH3CH2COOH is a weak acid using the correct justification
= Propanoic
Acid
=hydronium
=CHCH2COO
a. Propanic acid is a strong acid because it fully dissociates in aqueous solution
b. Propanic acid is a strong acid because it has a pH of less than 7
c. Propanic acid is a weak acid because it does not fully dissociate in aqueous solution
d. Propanic acid is a weak acid
because it has a pH of about 5

Final answer:

Propionic acid (CH3CH2COOH) is a weak acid as it only partially ionizes in water, similar to other carboxylic acids.


Explanation:

Propionic acid (CH3CH2COOH) is a weak acid based on its ionization constants. Carboxylic acids, including propionic acid, are weak acids as they only partially ionize in water, typically around 1%. In contrast, strong acids like hydrochloric acid (HCl) dissociate completely in water.
