Making Salts (Insoluble Bases)

A practical lesson looking at making salts from an insoluble base. I used Copper Oxide and Sulphuric Acid for the lesson, where the students fill in the equipment list and follow a method to make Copper Sulphate. Aimed at middle ability learners, but can be differentiated up/down if needed through the use of method/questions on worksheet. Method is on the worksheet and additional information is in the notes section of the PPT.

Starter - Students write down their own examples of salt making reactions involving metals, metal oxides, metal carbonates and acids. Can add in symbol equations as a challenge task for student challenge.

Main - Introduction to the experiment by describing the reaction of insoluble salts with acid. Students copy down the equipment list onto their worksheet before following the method on the worksheet to react Copper Oxide with Sulphuric Acid. During the practical, there are 6 questions to answer relating to the experiment to complete.

Plenary - Naming salts task on the worksheet using the key from the starter as help. Symbol equations are written underneath as a student challenge task.

Objectives:

GOOD – NAME salts formed between a metal oxide/hydroxide and an acid

GREAT – DESCRIBE a method to prepare a dry soluble salt from and insoluble substance and an acid

EPIC – EXPLAIN why the reaction between a base and dilute acid is a neutralisation reaction

As always, any feedback is welcome :)
