Question

Which of the following will form a solution? (Select all that apply.)

string and water
sand and water
sugar and water
salt and water

Answer 1

Sugar and water

Because those two can mix the others can’t mix

Answer 2

Sugar and Water

Salt and Water

Step-by-step explanation:

If you mix sand (or string) with water, it is a mixture, but it is not a solution. The sand (and string) cannot dissolve into the water.

So, when “Sugar” is added to water, the sugar “dissolves” into the water creating a “sugar water” solution. Salt and water also mixes to become a solution.

(If you want to see your for yourself, put a cup of water in the microwave and heat it up, then take it out (be careful when taking it out). Put a little bit of salt (or sugar) into the cup and it will eventually dissolve in the water)

Just think of it like powdered lemonade, but instead of it turning yellow it's clear. But it will still taste good (if you use sugar, because that's essentially what lemonade is)
