Rates Of Reaction

Question 1

What’s the experiment about?

Answer 1

Testing the rate of reaction of a solution, to see if the drawn cross on the paper under the flask could still be seen under a matter of time, before the solution becomes a thick colour resulting in not being able to see the cross on the paper.

Question 2

Step 1:

Answer 2

Mix 50cm cubed sodium thysulfate with 10 of hydrochloric acid

Question 3

Step 2:

Answer 3

Starts off with the most concentrated thysulfate, which is around 40 grams per decimetre, then measure 50 cm cubed of it cubed

Question 4

Step 3:

Answer 4

Then pour that solution up to 50 cm cubed in the measuring cylinder, then pour that measured amount into the beaker

Question 5

Step 4:

Answer 5

Measure 10cm cubed of the acid

Question 6

Step 5:

Answer 6

Then when the acid and the solution are mixed start the timer.

Question 7

Step 6:

Answer 7

When the cross is no longer visible, stop the timer and note down how long it took for that concentration to turn into a solid block colour

Question 8

Step 8:

Answer 8

Reaction time is longer so that means that the rate is smaller, now repeat this
