The Factors Affecting the Rate of Reaction of Indigestions Tablets With Acid

The Factors Affecting the Rate of Reaction of Indigestions Tablets With Acid

Planning,

To start the investigation I thought about what affected rates of

reaction. I managed to come up with 4 ideas:

1 Surface area

2 Temperature

3 Concentration

4 Mixing of the substances (stirring)

I decided to do 2 different preliminary experiment so I could chose

the best variable to investigate and see what equipment was necessary

to provide us with an accurate set of data.

Our first Preliminary experiment was testing what affect heat had on

the rate of reaction.

I planned a basic experiment,

· I took a heatproof mat and placed a Bunsen burner on it.

· I then put a tripod directly above the Bunsen burner on which I

placed a conical flask with a bung and delivery tube tightly attached

on.

· I fed the delivery tube into a bowl of water.

· Then a measuring cylinder was filled up with water, (to the very top

of the cylinder) the cylinder was then turned upside down whilst a

hand was placed over the open hole of the cylinder with pressure

letting no water out. It was the placed under the water in the bowl

(hole first).

· I removed the hand that was covering the hole of the tube when it

was under the water of the bowl. The water remains inside the cylinder

all the way to the top, this will allow us to see how much gas is

given off by the amount of water forced out of the tube.

· The delivery tube was then placed inside of measuring cylinder (to

collect any gas given off).

· A timer was needed to time how long the experiment took.

· The Conical flask was then filled up with 100cm3 of acid; this was

then heated to the desired temperature (of which there was 5).

· An indigestion tablet was then placed in the conical flask and the

bung was then tightened on.
