Explicitly the aim of today was to use a metal oxide and explain the reaction with an acid and from this to extrapolate to wider conclusions.
What I want to see in your conclusion is the following:
- What did you observe?
- What do you expect to see in the evaporating dish tomorrow?
- What reaction happened? How could you tell that a reaction had occured?
- What happens when acids are reacted with metal oxides? Take a look at P101 for more ideas on this.
- What type of salt is always produced when sulphuric acid is used in a neutralisation?
So I want you to comment on observations, explain them in equations if you can, and use your results to predict what will happen if similar experiments are carried out.
The worksheet you were given will give you some ideas on oxide reactions and are good practice.
If everything is as in the book, you should not have seen any bubbles coming off as no gas should have been produced. Some of you noticed some bubbles. Was there enough to call this fizzing? Would we say that gas is a major product here? If not where do we think it may have come from?
What could we have done better in this experiment? Rarely are experiments ever perfect.
Don't forget to write your own method
