When an acid is dissolved in water, which of the following correctly describes how its name is determined?

• A. If the acid contains an anion ending in -ide, the acid name ends with '-ous acid'.
• B. If the acid contains an anion ending in -ate, the acid name begins with 'hydro-' and ends with '-ous acid'.
• C. If the acid contains an anion ending in -ide, the acid name begins with 'hydro-' and ends with '-ic acid'.
• D. If the acid contains an anion ending in -ite, the acid name ends with '-ic acid'.

Answer: (C)

Verified step by step guidance

1. Understand that the naming of acids dissolved in water depends on the suffix of the anion from which the acid is derived.
2. Recall the general rules for acid nomenclature: if the anion ends in '-ide', the acid name begins with 'hydro-' and ends with '-ic acid'.
3. If the anion ends in '-ate', the acid name ends with '-ic acid' without the 'hydro-' prefix.
4. If the anion ends in '-ite', the acid name ends with '-ous acid' without the 'hydro-' prefix.
5. Use these rules to correctly determine the acid name based on the anion suffix, ensuring to avoid mixing the prefixes and suffixes incorrectly.
