Lab report: How the temperature of water will affect the reaction time of sodium thiosulfate and hydrochloric acid
Hanna Rokossa
Date: Week of 5th February
Aim:
The aim of this investigation is to find out if the temperature of the water can affect the reaction time of sodium thiosulfate and hydrochloric acid.
Prediction:
I predict that during this experiment when we increase the temperature of the water the faster the reaction will take place.
Variables:
IV- The thing that we are changing is the temperature of the water
DV- The thing we will be measuring is the time that will be taken for the reaction to happen
CV- Amount of Water (100ml)
The time we start and stop the timer
Method:
1.Put on your lab coat and goggles
2.Gather all you equipment
3. Draw an 'x' on three pieces of papers
4. Add 100 ml of 10degrees water to a beaker. If the tap water is not cold enough add some ice to the beaker to decrease the temperature.
5. Measure 10 ml of Sodium Thiosulfate and add this into a flask.
6. Put the flask into the beaker containing water
7.Measure 5ml of Hydrochloric Acid and pour that into the flask containing the Sodium Thiosulfate.
8.Make sure to have a piece of paper with an 'x' underneath the beaker.
9. Record your results on your results table
10.Repeat steps 4 to 9 two more times, then calculate your average for that temperature.
11. Add 100 ml of 50 degrees water into the beaker.
12. Measure 10 ml of Sodium Thiosulfate and add this into a flask.
13. Put the flask into the beaker containing water
14.Measure 5ml of Hydrochloric Acid and pour that into the flask containing the Sodium Thiosulfate.
15.Make sure to have a piece of paper with an 'x' underneath the beaker.
16. Repeat steps 11 to 15 two more times to get the average
17. Record your results and calculate the average.
18.Add 100 ml of 100 degrees water into the beaker.
19. Measure 10 ml of Sodium Thiosulfate and add this into a flask.
20. Put the flask into the beaker containing water
21.Measure 5ml of Hydrochloric Acid and pour that into the flask containing the Sodium Thiosulfate.
22.Make sure to have a piece of paper with an 'x' underneath the beaker.
23. Repeat steps 11 to 15 two more times to get the average
24. Record your results and calculate the average
25.Clear up all your equipment and clean your working space.
