Day 7

February 18th

After  I finished up with the first 4 sections of my plan I decided to finish up the rest of my plan as it was due handed in to the teacher in 5 days on the 23rd and i still had the risk assessment, method, and the risk assessment in which was needed to be signed. We only needed to have 3 total risks and ways to minimise the risk factor. In my risk assessment I decided to do 4 instead of 3 to list all the possible risks that may arise while doing my experiment. My risk assessment went as follows:

Risk	How this risk will be minimised
Beaker/Measuring Cylinder breaks	Wear enclosed shoes Wear safety goggles Handle with care Place beaker/measuring cylinder in the middle of the table so it cannot fall on the ground Clean up any broken glass with dust pan or broom, never pick up with your fingers.
Hydrochloric acid is inhaled/ or causes skin irritation	Wear apron, and gloves when handling hydrochloric acid. Pour hydrochloric acid into the measuring cylinders/beakers over the sink to reduce spillage.
Choking and Ingesting of tablets	Keep out of reach of children. Stay away from the tablets when dissolving.
Hydrochloric acid  can create eye damage as it is toxic	Wear safety goggles.

 

After my risk assessment was complete, it was time to do a brief description of what my method would be for this experiment. My method went as follows:

1. Pour 30mL hydrochloric acid into a beaker first measuring it by using a measuring cylinder
2. Repeat for other 3 beakers
3. Place each tablet into beaker
4. Stir 2 times
5. Time the results of the amount of time it takes to dissolve for each tablet
6. Repeat experiment 3 times for accurate results

With these two sections done of my plan I only had the risk assessment in which needed to be signed electronically done and ready to be handed in on Tuesday the 23rd.
