This is an overview of Topic 4: Acids. It includes common acids and alkalis, typical reactions and chemical equations.
Introduction to Acids and Bases
This video explains what an acid and base is and how they are chemical opposites and also highlights the difference between strong and weak bases.
Visualising Strong and Weak Acids
The video explains the difference between strong and weak acids and helps to visualise the difference.
Reactions of Acids and Bases
This video goes through the reaction of acids with alkalis, metal oxides, metal carbonates and metals including ionic equations of each reaction.
Making a Standard Solution
This video shows step by step how to make a standard solution using the apparatus needed.
Stock Solutions and Dilution
This video explains how to make a solution of required concentration from a stock solutions using dilution and how to calculate the volume of stock solution needed for the required concentration.
