Which of the following acids is stronger based on its dissociation constant ( $$K_a$$ )?

Hydrochloric acid ( $$K_a = 1.3 \times 10^6$$ )

Acetic acid ( $$K_a = 1.8 \times 10^{-5}$$ )

Formic acid ( $$K_a = 1.8 \times 10^{-4}$$ )

Citric acid ( $$K_a = 7.4 \times 10^{-4}$$ )

Which of the following acids is stronger: $$HClO_4$$ or $$HClO_3$$ ? Explain based on their molecular structure.

$$HClO_4$$ because it has more oxygen atoms, which stabilize the conjugate base.

$$HClO_3$$ because it has fewer oxygen atoms, making it less stable.

Which of the following statements is true regarding the acid strength of $$HF$$ , $$HCl$$ , $$HBr$$ , and $$HI$$ ?

$$HI$$ is the strongest acid because it has the weakest H-I bond.

$$HF$$ is the strongest acid because it has the smallest atomic radius.

$$HCl$$ is the strongest acid because it is the most commonly used.

$$HBr$$ is the strongest acid because it is in the middle of the group.

Identify the stronger acid between $$H_2CO_3$$ and $$H_2SO_3$$ and justify your choice based on their molecular structure.

$$H_2SO_3$$ because sulfur is more electronegative than carbon.

$$H_2CO_3$$ because it has a more stable conjugate base.

$$H_2CO_3$$ because it has more oxygen atoms.

$$H_2SO_3$$ because it has a higher oxidation state of the central atom.
