Question
The chemical reaction that produces soap is called saponification. During one type of saponification, oil and sodium hydroxide undergo a chemical change to produce glycerol and soap. As a result of this reaction, the soap has different properties than the oil and sodium hydroxide. Some of these properties are what give soap its cleaning ability. For each statement below, choose whether it is true or false. (1 point)
True False
A chemical change occurs during saponification.

Soap is a reactant of the saponification reaction.

Together, the products of a chemical reaction have the same arrangement of atoms as the reactants.

Answer 1

Let's evaluate each statement regarding saponification:

1. A chemical change occurs during saponification.

   • True: Saponification is indeed a chemical reaction, and during this process, a chemical change occurs as the reactants (oil and sodium hydroxide) transform into products (glycerol and soap).

2. Soap is a reactant of the saponification reaction.

   • False: In the saponification reaction, soap is one of the products, not a reactant. The reactants are oil and sodium hydroxide.

3. Together, the products of a chemical reaction have the same arrangement of atoms as the reactants.

   • False: In a chemical reaction, the arrangement of atoms changes; the reactants have different arrangements compared to the products. This is a fundamental principle of chemical changes.

So the answers would be:

1. True
2. False
3. False
