Magnesium Oxide Investigation
In this lab you will be putting into practice the skills and knowledge you have been gaining over the past few weeks. Your goal is to obtain the empirical formula for Magnesium Oxide. It is what is left when magnesium is burned in air; it looks white and powdery.
In groups you need to plan out how you will do the experiment. Consider all of the following:
- · What is your Research Question?
- · What safety precautions should you take?
- · What equipment will you need?
- · What are the reactants?
- · What measurements will you take?
- · How will you get the reaction to take place?
- · How will you process the data to obtain a formula?
- · What about safety (again!)?
As a group, write up your plan and take it to your teacher. Do not start any experimenting until you have been given the go ahead by your teacher.
Instructions:
Carry out your experiment.
Do your calculations…can you get a formula?
What level of confidence do you have in your answer?
What are the uncertainties in your experiment and what effect might they have on your answer?
Can you do more experimenting to verify it?
Now write up your experiment on your own.
Include:
- · Research Question
- · Procedure/Method
- · Data Collection
- · Data Analysis
- · Evaluation.
