Naming Acids Quiz

1. Which formula should be selected for perchloric acid?

2. During a lab, a student must label an aqueous solution of HBr. Which name is correct?

3. A student is asked to write the formula of nitric acid, which is derived from the nitrate ion NO3−. Which answer is correct?

4. The phosphite ion is PO3^3−. Which formula represents phosphorous acid, the corresponding “-ous” acid?

5. A student needs the formula for sulfuric acid. Which formula should the student write?

6. The sulfite ion forms H2SO3. Which name correctly reflects the change from the ion ending “-ite”?

7. The chlorate ion is ClO3−. Following the rule that an “-ate” ion forms an “-ic” acid, what is the name of HClO3?

8. A bottle contains aqueous HCl. Which name belongs on its acid label?

9. Four labels are proposed for HClO. Which one follows oxyacid naming rules?

10. A learner starts with the polyatomic ion name “sulfate.” Which acid-name ending should replace “-ate”?

11. Which name is conventionally used for aqueous HCN?

12. The acetate ion is C2H3O2−. Applying the “-ate” to “-ic acid” pattern and its conventional retained name, what is HC2H3O2 called?

13. An aqueous solution has the formula H2S. What is its binary-acid name?

14. A carbonate ion, CO3^2−, gains enough hydrogen ions to form the corresponding neutral acid. Which formula results?

15. Which name correctly identifies HNO2?

16. Two chlorine oxyacids, HClO2 and HClO3, are easily confused. What is the correct name of HClO2?
