## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Nomenclature and identification of common chemical compounds.
	**Related Topics**: Chemical formulas, hydrated salts, coordination complexes.
	**Prerequisites**: Basic knowledge of chemical nomenclature, familiarity with common salt names.
## SOLUTION PATHWAY
**Given Information**:
	Chemical formula: $m{FeS}{{m{O}}_4}.{\left( {m{N}}{{m{H}}_4} ight)_2}{m{\;S}}{{m{O}}_4}.6{{m{H}}_2}{m{O}}$
**Method & Steps**:
	1.	Recall the common name associated with the given chemical formula.
		Reasoning: This question requires direct recall of a specific chemical name.
	2.	Identify the correct name.
		Result: The compound $m{FeS}{{m{O}}_4}.{\left( {m{N}}{{m{H}}_4} ight)_2}{m{\;S}}{{m{O}}_4}.6{{m{H}}_2}{m{O}}$ is known as Mohr's salt.

## OPTION ANALYSIS
[A] :x: Green salt is usually associated with ferrous sulfate heptahydrate ($FeSO_4.7H_2O$).
[B] :x: Glauber's salt is the common name for sodium sulfate decahydrate ($Na_2SO_4.10H_2O$).
[C] ✓: Mohr's salt is the correct name for the given compound, which is a double salt of ferrous sulfate and ammonium sulfate.
[D] :x: Alum is a generic term for a variety of double sulfate salts, often involving aluminum, potassium, or ammonium.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing Mohr's salt with other similar-sounding or visually similar salts.
		2.[Error 2]: Not knowing the common names for hydrated salts.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember the key components of Mohr's salt: iron(II) sulfate, ammonium sulfate, and six waters of hydration.
		2.[Memory aid]: Associate 'Mohr' with the 'M' in ammonium to remember the ammonium component of the salt.
