Indicate whether each of the following statements is correct or incorrect. 1) Every Bronsted-Lowry acid is also a Lewis acid2) Every Lewis acid is also a Bronsted-Lowry acid. 3) Conjugate acids of weak bases produce more acidic solutions than conjugate acids of strong bases. 4) K + ion is acidic in water because it causes hydrating water molecules to become more acidic.

1) correct

2) incorrect

3) correct

4) incorrect

Explanation:

1) A Lewis acid is a substance that accepts a nonbonding pair of electrons.

A Bronsted-Lowry acid is a substance that donates a proton H⁺

Since the donation of a proton involves the acceptance of a pair of electrons, every Bronsted-Lowry acid is also a Lewis acid.

2) A Lewis acid not necessarily needs to have a proton to be donated.

3) Conjugated acids of weak bases are strong acids and conjugated acids of strong bases are weak acids.

4) K⁺ comes from a strong base, therefore is does not have an acidic behaviour.
