    A. a weak acid and a strong base

    Explanation:

    An acid-base reaction is a chemical reaction between an acid and a base to form salt and water. The reaction is also known as a neutralization reaction.

    An acid is a compound that when in aqueous solution it dissociate to form an hydrogen ion (H+).

    A base is a compound that when in aqueous solution it produces an hydroxide ion (OH-).

    A strong acid is an acid that completely dissociate in an aqueous solution.

    A strong base is a base that completely dissociate in an aqueous solution.

    The reaction that produce a salt like sodium carbonate is a chemical reaction between a weak acid and a strong base. The chemical reaction can be represented as follows

    H2CO3 + 2NaOH → Na2CO3 + 2H2O

    H2CO3 is a weak acid as it partially dissociate in aqueous solution.

    NaOH is a strong base as it completely dissociate in aqueous solution.

    Na2C03 is formed through the reaction of

    NaOH and H2CO3 namely sodium hydroxide and carbonic acid

    NaOH - > strong base

    H2CO3-> weak acid
