Among the following statements the incorrect one isa)calamine and side...
Incorrect Statement:
Option B: Argentite and cuprite are oxides.
Explanation:
Argentite and cuprite are not oxides, but rather sulfides and oxide respectively.
- Argentite (Ag2S) is a sulfide mineral of silver, containing silver and sulfur. It is an important ore of silver.
- Cuprite (Cu2O) is an oxide mineral of copper, consisting of copper and oxygen. It is also known as red copper ore.
Correct Statements:
Option A: Calamine and siderite are carbonates.
- Calamine (ZnCO3) is a carbonate mineral of zinc, containing zinc, carbon, and oxygen. It is an important source of zinc.
- Siderite (FeCO3) is a carbonate mineral of iron, containing iron, carbon, and oxygen. It is an important source of iron.
Option C: Zinc blende and iron pyrites are sulphides.
- Zinc blende (ZnS) is a sulfide mineral of zinc, containing zinc and sulfur. It is the primary ore of zinc.
- Iron pyrites (FeS2) is a sulfide mineral of iron, containing iron and sulfur. It is commonly known as "fool's gold."
Option D: Malachite and azurite are ores of copper.
- Malachite (Cu2(CO3)(OH)2) is a carbonate mineral of copper, containing copper, carbon, oxygen, and hydrogen. It is a secondary mineral formed from the weathering of primary copper ores.
- Azurite (Cu3(CO3)2(OH)2) is also a carbonate mineral of copper, containing copper, carbon, oxygen, and hydrogen. It is a secondary mineral formed from the oxidation of copper ores.
Therefore, the incorrect statement is Option B: Argentite and cuprite are oxides.
Option B: Argentite and cuprite are oxides.
