Acids and Alkalis: Changing a Neutral Solution

Acids and Alkalis: Changing a Neutral Solution

Learning Objectives

At the end of the lesson you will understand that both metals and non-metals burn in air to form oxides.
At the end of the lesson you will know that some metal oxides dissolve in water to form alkalis.
At the end of the lesson you will learn that most metal oxides are insoluble in water and are called bases.
At the end of the lesson you will understand that non-metal oxides that dissolve in water form acids, including three that have environmental consequences.

What do you already know about acids and bases?

Formation of alkalis from soluble oxides.
Classification of metal oxides.

Insoluble Metal Oxides

Most metal oxides are insoluble.
Characteristics of bases.
Examples of insoluble metal oxides.

Non-Metal Oxides and Their Impacts

Non-metal oxides dissolve in water.
Formation of acids from non-metal oxides.
Environmental consequences of certain non-metal oxides.

Definition List

pH: A measure of the acidity or alkalinity of a solution, with lower values indicating acidity and higher values indicating alkalinity.
Metal Oxides: Compounds formed when metals react with oxygen, which can be soluble or insoluble, affecting their classification as alkalis or bases.
Non-Metal Oxides: Compounds formed when non-metals react with oxygen, usually dissolving in water to form acids.
Soluble: A substance's ability to dissolve in a solvent, such as water.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
