Also today I did my Presence of Salt (Sodium Chloride) Test, this was done in period 6 today.
- Firstly I gathered equipment that was needed; 5 small beaker, sodium chloride and gloves, waste bucket.
- I then gathered each of the 5 beakers and poured each of the 5 water samples into each of the beakers.
- I then started to drop drops of sodium chloride into the water samples, if no change has occured, keep adding drops until some change has occured (colour change).
- After all tests have been done on all 5 samples of water, pour each of the sodium chloride solutions into a waste bucket NOT down the sink.
- Record results and clean up
results shown below;
beaker 1: 2 drops = high
beaker 2: 2 drops = high
beaker 3: 2 drops = high
beaker 4: 6 drops = low
beaker 5: 3 drops = meduim
wow rose, you have been working very hard. what a shame that your soil testing for moisture & organics went so wrong! oh well, you still have time and now it's all clear.
ReplyDeleteYour posts are all very thorough which is great, i would just suggest you put the data into tables. This way you save time, when the official report is due you can just copy and paste the tables instead of having to rewrite them again.
