OSE 7.1 Chemical Reactions Lesson 3

Front

In the context of bath bombs, what does the word soluble mean?

Back

The ability to dissolve in water

Front

What does it mean if an ingredient is insoluble?

Back

It does not dissolve in water.

Front

What new question could you have based on the investigation into mixing with water?

Back

What else can cause the bubbles to appear?

Front

What is the purpose of mixing the ingredients with water?

Back

To observe if gas bubbles form

Front

What might you conclude if no gas bubbles are produced during the experiment?

Back

The combination of ingredients and water does not produce a reaction.

Front

What would be the best way to measure the reaction rate of gas bubbles from the ingredients in water?

Back

By timing how quickly they appear and disappear

Front

Comparing all recipes, which ingredient is used in every one? Options: Baking soda, Citric acid, Epsom salts, Olive oil

Back

Baking soda

Front

What evidence would help determine how a bath bomb produces gas bubbles?

Back

Recording which mixtures produce bubbles when combined with water

Front

What pattern can you observe from the ingredients listed in the bath bomb recipes?

Back

They include a source of acid and a base.

Front

What new question could be valuable for investigating bath bomb ingredients?

Back

What combinations of other ingredients might also produce gas?
