Question

Substance A dissociates 100% in water to produce H3O+ ions while substance B dissociates 25% in water to produce OH- ions. What can be determined from this information?

A:Substance A is a strong acid and substance B is a weak base
B:Substance A is a weak acid and substance B is a strong base
C:Substance A is a strong base and substance B is a weak acid
D:Substance A is a weak base and substance B is a strong acid

Answer 1

a

Step-by-step explanation:

Answer 2

A:Substance A is a strong acid and substance B is a weak base

Step-by-step explanation:

From this information, we can conclude that substance A is a strong acid and substance B is a weak base.

A strong acid is one that ionizes completely in solution. Most strong acids are usually concentrated. 100% dissociation is a complete ionization.

A weak base ionizes slightly in an aqueous solution. 25% dissociation is weak ionization.
