Scelta multipla
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'.

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