Question

Consider a binary acid, represented as HA, in which one or more ionizable H atoms are bonded to one additional element. HA is not an oxoacid. Which of the following statements correctly summarize the influence of partner A on the strength of the acid HA? Choose one or more:

HA becomes more acidic as the number of ionizable H atoms in the structure increases.

For partner atoms in the same group, HA becomes more acidic as A increases in size.

HA will always become more acidic as the electronegativity of A increases.

HA becomes more acidic as the partner atom A becomes more metallic.

For partner atoms in the same period, HA will become stronger as A becomes smaller.
