Question 1

What is the difference between a mixture and a solution?

Accepted Answer

A mixture is two or more substances combined without forming something new. A solution is a special mixture where one substance dissolves completely and evenly into another. Every solution is a mixture, but a mixture is only a solution if the parts dissolve evenly, like salt in water.

Question 2

What is a solution in science?

Accepted Answer

In science, a solution is a mixture in which one substance dissolves completely and evenly into another, so you cannot see the separate parts or filter them out. Salt water and sugar water are common examples.

Question 3

Which mixtures are solutions?

Accepted Answer

A mixture is a solution when its parts dissolve completely and evenly, leaving no visible pieces and nothing to filter out. Salt water, sugar water, and lemonade are solutions. Sand in water, trail mix, and oil and water are mixtures but not solutions, because the parts stay separate.

Question 4

Is salt water a mixture or a solution?

Accepted Answer

Salt water is both. It is a mixture because the salt and water are combined without making a new substance, and it is a solution because the salt dissolves completely and evenly into the water. That makes it a classic example of a solution.
