Question

In each equation, label the acids, bases, and conjugate acid-base pairs. (Type your answer using the format [NO3]- for NO3-.)

Answer 1

Answer:

a) O²⁻ + H₂O <-----> OH⁻ + OH⁻

Acid = H₂O

Base = O²⁻

Conjugate Acid = OH⁻

Conjugate Base = OH⁻

b) HClO₄ + H₂SO₄ <-----> ClO₄⁻ + H₃SO₄⁺

Acid = HClO₄

Base = H₂SO₄

Conjugate Acid = H₃SO₄⁺

Conjugate Base = ClO₄⁻

c) NH₃ + HNO₃ <--> NH4⁺ + NO₃⁻

Acid = HNO₃

Base = NH₃

Conjugate Acid = NH4⁺

Conjugate Base = NO₃⁻

Explanation:

- Acids are molecules or ions capable of donating a proton (H⁺).

- Bases are molecules or ions that readily accept the H⁺ from acids.

- Conjugate Acids, according to the Brønsted–Lowry acid–base theory, are chemical compounds formed after the reception of a proton (H⁺) from an acid by a base.

- Conjugate Bases, Brønsted–Lowry acid–base theory, are the leftovers from when acids donate their proton (H⁺).
