Concentration and Solutions Flashcard

Front

What is a solution?

Back

A mixture where one substance (solute) is dissolved in another (solvent).

Front

What is a solute?

Back

The substance that is dissolved in a solution.

Front

What is a solvent?

Back

The substance that dissolves the solute in a solution.

Front

How can you make a solution less concentrated?

Back

By adding more solvent.

Front

What is concentration?

Back

The amount of solute present in a given volume of solution.

Front

What is mass percent?

Back

A way to express the concentration of a solution as the mass of solute divided by the total mass of the solution, multiplied by 100.

Front

How do you calculate mass percent?

Back

(mass of solute / total mass of solution) x 100.

Front

What is the formula for concentration in grams per milliliter?

Back

Concentration = mass of solute (grams) / volume of solution (milliliters).

Front

Which solution is more concentrated: 50 grams of sugar in 100ml water or 75 grams of sugar in 100ml water?

Back

75 grams of sugar in 100ml water.

Front

What happens to the concentration of a solution when more solute is added?

Back

The concentration increases.
