This shows that the collision theory must be taking place as said in my prediction. In conclusion I found that the more water that was added the sodium thiosulphate and the dilute disappearing cross experiment coursework acid the longer it took for the cross coursewokr disappear.

I could have done more tests to gain a more reliable average.

#

Chemistry Rates of Reaction Coursework: If the solution is diluted, there aren't as many acid particles to collide with the thio particles and so the reaction is much slower.

#

#

Repeat steps 3 - 6, but reduce the concentration of hydrochloric acid to 6 ml and add 4ml of water.

I would also make sure my measurements are much more accurate, and do the experiment more times. He was completely horrified with the scene. In our experiment, we are reacting it with sodium thiosulphate. Delete comment or cancel.

After 5 seconds I will stir the solution for 15 seconds exactly, no longer and no less for all the experiments to keep the test fair.

Sodium Thiosulphate and Hydrochloric Acid Essay As a result of its broad audience, many people don't realize that physics plays a large role in cross-country skiing.

I predicted that the more water added the longer it takes for the cross to disappear. French and Italians had a battle against Austrians. The following is the apparatus that I will be using to conduct my experiment. Record this time and repeat this for different concentrations of hydrochloric acid. Cross-country skiing is enjoyed by people of all ages, and can be relatively inexpensive. The Community service involved working with the Red Cross in the Dar es salaam International Trade Fair[DITF] which was on at the time and we were allocated to work at the Red Cross tents at the Fair ground to help administer first aid to any causalities.

We then added the contents of the cylinder to the conical flask along with the 25cm3 sodium thiosulphate. To do this we added water to the acid and did the experiment again 4 times, decreasing the concentration of the acid by 5cm3 each time.
