Verified step by step guidance1
Understand the definition of a homogeneous mixture: it is a mixture that has a uniform composition and appearance throughout, meaning you cannot distinguish its different components by the naked eye.
Analyze each option to determine if it fits the definition of a homogeneous mixture:
Salt water: Salt dissolves completely in water, forming a uniform solution where the salt particles are evenly distributed at the molecular level.
Sand and iron filings: This is a heterogeneous mixture because you can see and separate the different components physically; the sand and iron filings are not uniformly distributed.
Granite: Granite is a solid rock composed of different minerals visibly mixed together, so it is a heterogeneous mixture.
Vegetable soup: This contains various solid pieces of vegetables and other ingredients suspended in liquid, making it a heterogeneous mixture.
