AQA GCSE Chemistry: Learn about Acids, Alkalis, and Salt Production

Covers the reactions of acids with metals, metal oxides, metal hydroxides, and metal carbonates to produce salts. Includes the pH scale, neutralisation, and the definition of strong and weak acids in terms of ionisation for Higher Tier students.

Lesson#1
In this deck, you will learn about acids and alkalis. We will explore the pH scale, what happens during a neutralisation reaction, and how different reactions can be used to produce a variety of salts. We'll also cover the distinction between strong and weak acids, which is important for Higher Tier students.
Lesson#2
To measure how acidic or alkaline a solution is, scientists use the pH scale. This scale typically runs from 0 to 14. A pH of 7 is neutral, which is the pH of pure water. Anything below 7 is acidic, and anything above 7 is alkaline. The lower the number, the more acidic the solution, and the higher the number, the more alkaline it is.
Quiz#3
What scale is used to measure the acidity or alkalinity of a solution?

the pH scale

Quiz#4
On the pH scale, what number represents a completely neutral solution?

7

Quiz#5
On the pH scale, what does a value below 7 indicate?

acidic

Quiz#6
On the pH scale, what does a value above 7 indicate?

alkaline
