some methods to separate mixtures are listed below\nmethods to separate mixtures\n1. pass a magnet over the mixture to pull out the salt\n2. boil the mixture to evaporate the water\n3. pour the mixture through a kitchen sieve\n4. use tweezers to pick out the salt\na student is given a beaker containing salt and water. which of these methods could the student use to separate the salt from the water?\na method 2\nb method 1\nc method 3\nd method 4
Answer
Explanation:
Step1: Analyze Method 1
Salt is not magnetic, so a magnet cannot pull out salt.
Step2: Analyze Method 2
Boiling the salt - water mixture causes water to evaporate, leaving salt behind. This is a valid separation method for salt - water mixtures.
Step3: Analyze Method 3
A kitchen sieve is used to separate solid particles of different sizes. Salt in water is dissolved, so a sieve cannot separate it.
Step4: Analyze Method 4
Salt is dissolved in water and is too small to be picked out with tweezers.

A. Method 2
