1. The investigation
Plan and carry out an investigation to determine the rate equation for the reaction between Mg and HCl. How?
Find and read the research papers
Make notes on factors that you could investigate, what you will change, how you will carry out your experiment
Plan your experiment
Carry out trial experiments
Collect your results
Produce a graph and results tables
Write up the project in the form of a report

2. What you will be given Magnesium ribbon 2 moldm-3 HCl

5. Intro
Read the abstract to get an idea of the premise behind the paper.
Skip to the conclusion to get an idea of where the proposed research ends up.
Scan the article to get an idea of the main points of discussion.
Take ROUGH notes of KEY points as you read .
Decide what aspects if the article are most important to you (in the context of your experiment).
Condense the article into 4 main section…
Defining the research question
Summarising the methodology
Summarising the results
Relating this to your study
1 page of A4 should be more than sufficient.

6. Method Method Justification or or Errors
Which method had the lowest error?
Which is the most suitable?

7. Method Risk assessment
List all the chemicals you intend to use or make. Give the approximate quantities in each case, and state whether the substance will be in pure form or in solution. If in solution, at what concentration?
For each substance, identify the hazards. State whether it is: flammable, harmful, irritant , oxidizing, explosive, toxic, corrosive , radioactive If there is a maximum exposure limit, state this also. Use the references listed below to help you. For example, you could use suppliers’ catalogues to identify the hazardous chemicals and then look up the conditions of use on the Hazcards.
Identify any hazards that may arise during the operations you will carry out – for example, there may be a highly exothermic reaction when two chemicals are mixed.
Give the safety precautions you will use when handling each of the hazardous substances, or carrying out hazardous operations.
Make sure that you include your completed Risk Assessment in the Planner form and discuss it with your teacher. Remember that if you change your plans you may need to change your Risk Assessment.

8. Trials Mg(s) + 2HCl(aq)  MgCl2(aq) + H2(g) Potential variables
Mass?
Size and shape?
Flat or curled?
Oxide layer that forms?
When Mg had fully reacted, reaction has finished?
HCl
Volume?
Concentration? H2
Volume collected?
When H2 reaches 100cm3 reaction finished?
Overall
Exothermic reaction, how will this affect the rate?
What combinations do we need?
Mg(s) HCl(aq)  MgCl2(aq) H2(g)
This is a lot to consider when planning an experiment from scratch. We will give you some suggestions on quantities but ultimately this is YOUR experiment.

9. Trials Write up Which trials did you do and why? Results tables?
How did the trials inform your variables?
