Question

In which of the following are the symbol and name for the ion given correctly?

a. NH₄ : ammonia; H : hydride
b. C₂ H₃ O₂ : acetate; C₂ O₄ : oxalite
c. OH : hydroxide; O₂ : oxide
d. PO₃³ : phosphate; PO₄³ : phosphite

Answer 1

None of the options provided correctly match the symbol and name for both ions listed. Each option contains at least one error in the naming or symbol of the ions.

Step-by-step explanation:

The student is asking which of the given options correctly matches the symbol and name for the ion. To answer the question:

• NH₄+ is correctly named ammonium, not ammonia, so option a is incorrect.
• C₂H₃O₂- is correctly named acetate, but C₂O₄ should be named oxalate, not oxalite, making option b incorrect.
• OH- is correctly named hydroxide, and O₂2- is correctly named peroxide, so option c is incorrect because O₂- represents oxide, not O₂2-.
• PO₃3- should be phosphite, while PO₄3- is correctly named phosphate, so option d is incorrect.

Therefore, none of the given options correctly match the symbol with the name for both ions listed.
