Lesson 1.2: Using Concentrated Solutions to Reduce Garbage

Concentration was defined as the amount of solute in a solution.  So the more solute you have in the solution the more concentrated the solution.  If you buy a concentrated product you will likely have to dilute it before you can use it.  Read page 60 to learn how concentrated solutions can reduce garbage.

Question 1. What  is meant by a concentrated product?

Question 2. Give five examples of concentrated products.

Question 3. When you make a concentrated product do you reduce the amount of solute or solvent?

Question 4. When you dilute a concentrated product do you reduce the amount of solute or solvent?

Question 5. When you dilute a concentrated product do you increase the amount of solute or solvent?

Answers to Questions:

Question 1. What  is meant by a concentrated product?

A concentrated product means that the contents must be diluted before they can be used.

Question 2. Give five examples of concentrated products.

Five examples that were given in the reading were concentrated fruit juice, instant coffee, canned soup, packaged salad dressing, and dehydrated foods.  Your list may have included other products.

Question 3. When you make a concentrated product do you reduce the amount of solute or solvent?

In order to make a concentrated product you have to reduce the amount of solvent.  For example, the solvent in most foods is water.  In order to concentrate the food, you remove water.

Question 4. When you dilute a concentrated product do you reduce the amount of solute or solvent?

You do not reduce the amount of solute or solvent when you dilute a concentrated product.  You increase the amount of solvent in dilution.

Question 5. When you dilute a concentrated product do you increase the amount of solute or solvent?

You increase the amount of solvent when you dilute a concentrated product.  For example, add a teaspoon of salt to a glass of water.  Then dilute the solution by pouring it into a lager container and add 4 glasses of water.  There is still one teaspoon of salt in the solution.  There is just more water in the dilute solution.
