Acids and Bases: Acid Neutralization

A chemical reaction takes place when we combine an acid and a base. This reaction is called neutralization and the equation is: acid + base → salt + water. For example, if we mix hydrochloric acid with sodium hydroxide, they will react and produce sodium chloride and water. There are many examples where this is useful. If a stomach produces an excess of acid, this can cause indigestion. Taking medication, such as milk of magnesia (which is basic), can neutralize the acid and relieve the discomfort.

In this activity, students will identify and create illustrations for the practical applications of neutralization. Have students use books and the internet to research these and then display them in a spider map. They can support their writing with visual elements.

Student Instructions

1. Click "Start Assignment".
2. In the titles, identify each practical use.
3. Write a sentence summarizing each one in the description boxes.
4. Create an illustration for the application using a combination of scenes, characters, and items.
