Question

Explain the definitions of acid and base of ① - ③ , respectively.

① Arrhenius acid and base

② Brønsted — Lowry acid and base

③ Lewis acid and base Select acids and bases from substances (1) - (6).

( 1 ) H₃O⁺ ( 2 ) OH⁻ ( 3 ) NH₃ ( 4 ) NH₄⁺ ( 5 ) Fe³⁺ ( 6 ) Br⁻

 

Answer 1

Arrhenius acid - a substance that donates a proton (H⁺) ion

Arrhenius base - a substance that accepts provides OH^- ions

 

Bronsted-Lowry acid - a substance that donates a proton (H⁺)

Bronsted-Lowry base - a substance that accepts a proton

 

Lewis acid - substance that accepts a pair of electrons

Lewis base - substance that donates a pair of electrons

 

 

H₃O⁺ = acid

OH^- = base

NH₃ = base

NH₄⁺ = acid

Fe₃⁺ = acid

Br^- = base
