Question

name the following acids: 9. hclo3(aq) 10. h2cr2o7(aq) 11. hc2h3o2(aq) 12. h2so4(aq)

Explanation:

Step1: Identify acid - naming rules

For oxy - acids (acids containing oxygen), if the central non - metal has a common name, the name is based on the oxidation state of the central atom. If the central atom has a higher oxidation state in one of a pair of oxy - acids, it is named with the suffix “-ic” and the prefix “per -” if applicable. If it has a lower oxidation state, it is named with the suffix “-ous” and the prefix “hypo -” if applicable. For binary acids (acids with hydrogen and one other non - metal), the name starts with “hydro -” and ends with “-ic acid”. Organic acids have their own naming conventions based on the parent hydrocarbon and the carboxyl group.

Step2: Name HClO₃

The central atom is chlorine. In HClO₃, chlorine has an oxidation state of + 5. The name is chloric acid.

Step3: Name H₂Cr₂O₇

The central atom is chromium. H₂Cr₂O₇ is an oxy - acid. The name is dichromic acid.

Step4: Name HC₂H₃O₂

This is an organic acid. It is acetic acid.

Step5: Name H₂SO₄

The central atom is sulfur. In H₂SO₄, sulfur has a high oxidation state. The name is sulfuric acid.

Answer:

1. Chloric acid
2. Dichromic acid
3. Acetic acid
4. Sulfuric acid
