Question

question 3
what is the difference between an acid and its conjugate base?
the presence of an extra proton in the acid
the presence of an extra electron in the acid
the presence of an extra proton in the conjugate base
the presence of an extra electron in the conjugate base

question 4
strong acids and bases
can burn your skin at any concentration.
are flammable and explosive.
dissociate completely in solution.
decompose easily to form gases.

Explanation:

• For Question 3: According to the Brønsted - Lowry theory, an acid donates a proton (\(H^{+}\)) to form its conjugate base. So, the acid has an extra proton compared to its conjugate base.
• For Question 4: By definition, strong acids and bases dissociate completely in solution. For example, \(HCl\) (a strong acid) dissociates as \(HCl

ightarrow H^{+}+Cl^{-}\) and \(NaOH\) (a strong base) dissociates as \(NaOH
ightarrow Na^{+}+OH^{-}\) in solution.

Answer:

• Question 3: The presence of an extra proton in the acid
• Question 4: dissociate completely in solution
