Which of the following options are homogeneous mixtures?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Salt water, brass.
The correct option that includes homogeneous mixtures is "Salt water, brass."
Salt water is a solution where the salt is evenly dissolved in water, making it a homogeneous mixture. Brass is an alloy of copper and zinc, mixed uniformly at the molecular level, also making it homogeneous. The other options, including colloids, suspensions, milk, and toothpaste, are heterogeneous mixtures, as they contain components that are not uniformly distributed.
