Short Answer

Expert verified
\(a. HCN \\ b. HNO_3 \\ c. H_2SO_4 \\ d. H_3PO_4 \\ e. HClO \\ f. HBr \\ g. HBrO_2 \\ h. HF\)

Step by step solution

01

a. Hydrocyanic acid

Hydrocyanic acid is a weak acid containing hydrogen and the cyanide ion (CN⁻). The formula for hydrocyanic acid is formed by combining a hydrogen ion (H⁺) with a cyanide ion (CN⁻). The formula is: H⁺ + CN⁻ → HCN
02

b. Nitric acid

Nitric acid is a strong acid and consists of the nitrate ion (NO₃⁻) and a hydrogen ion (H⁺). The formula for nitric acid is: H⁺ + NO₃⁻ → HNO₃
03

c. Sulfuric acid

Sulfuric acid is another strong acid and contains the sulfate ion (SO₄²⁻) and two hydrogen ions (2H⁺) since the sulfate ion has a 2- charge. The formula for sulfuric acid is: 2H⁺ + SO₄²⁻ → H₂SO₄
04

d. Phosphoric acid

Phosphoric acid is a weak acid and consists of the phosphate ion (PO₄³⁻) and three hydrogen ions (3H⁺) since the phosphate ion has a 3- charge. The formula for phosphoric acid is: 3H⁺ + PO₄³⁻ → H₃PO₄
05

e. Hypochlorous acid

Hypochlorous acid is a weak acid containing hydrogen and the hypochlorite ion (ClO⁻). The formula for hypochlorous acid is formed by combining a hydrogen ion (H⁺) with a hypochlorite ion (ClO⁻). The formula is: H⁺ + ClO⁻ → HClO
06

f. Hydrobromic acid

Hydrobromic acid is a strong acid containing hydrogen and the bromide ion (Br⁻). The formula for hydrobromic acid is formed by combining a hydrogen ion (H⁺) with a bromide ion (Br⁻). The formula is: H⁺ + Br⁻ → HBr
07

g. Bromous acid

Bromous acid is a weak acid containing hydrogen and the bromite ion (BrO₂⁻). The formula for bromous acid is formed by combining a hydrogen ion (H⁺) with a bromite ion (BrO₂⁻). The formula is: H⁺ + BrO₂⁻ → HBrO₂
08

h. Hydrofluoric acid

Hydrofluoric acid is a weak acid containing hydrogen and the fluoride ion (F⁻). The formula for hydrofluoric acid is formed by combining a hydrogen ion (H⁺) with a fluoride ion (F⁻). The formula is: H⁺ + F⁻ → HF
