Question

directions:
write the correct name or formula for each compound
binary acids

1. hcl (aq) → hydrochloric acid
2. h₂s (aq) →
3. hbr (aq) → hydrobromic acid
4. hydroiodic acid → h₃p(aq)
5. hydrophosphoric acid →

oxyacids

1. hno₃ → nitric acid
2. hno₂ → nitrous acid
3. h₂so₄ → sulfuric acid
4. h₂so₃ →

Explanation:

Step1: Binary acid naming rule

Binary acids are named as "hydro - non - metal root name - ic acid". For \(H_2S(aq)\), the non - metal is sulfur.

Step2: Apply the rule

Using the rule, \(H_2S(aq)\) is named as hydrosulfuric acid.

Step3: Hydroiodic acid formula

Hydroiodic acid is a binary acid. The non - metal is iodine (\(I\)). The formula for hydroiodic acid is \(HI(aq)\) (not \(H_3P(aq)\) as wrongly written in the original).

Step4: Hydrophosphoric acid formula

Hydrophosphoric acid is a binary acid. The non - metal is phosphorus (\(P\)). The formula is \(H_3P(aq)\)

Answer:

1. hydrosulfuric acid
2. \(HI(aq)\)
3. \(H_3P(aq)\)
