13. Which of the following will not form a solution?
a. preparing a salad dressing
b. mixing ice cubes with water
c. preparing a glass of iced tea
d. adding a spoonful of sugar in water


Sagot :

Answer:

The answer is b. mixing ice cubes with water. Here's why:

- Solutions are homogeneous mixtures where one substance (the solute) dissolves completely into another substance (the solvent).

- Ice cubes in water don't form a solution because the ice cubes are a solid, and they don't dissolve into the water. They simply cool the water.

Let's look at the other options:

- a. preparing a salad dressing: Salad dressings often involve oil and vinegar, which don't mix completely, making it a heterogeneous mixture, not a solution.

- c. preparing a glass of iced tea: Iced tea is a solution because the tea leaves or powder dissolve in the water.

- d. adding a spoonful of sugar in water: Sugar dissolves in water, forming a homogeneous mixture, which is a solution.
