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