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.

Investigating the Rate of Reaction Between Marble Chips and Acid Introduction This is a test to demonstrate the reaction rate between marble chips (CaCO) and hydrochloric acid (HCl). Hopefully we will be able to prove that the concentration of the acid is directly proportional to the reaction rate. Aim To discover if the concentration of acid is directly proportional to the rate of reaction, by monitoring the amount of gas given off as the reaction takes place. Prediction We believe that the concentration of the acid will be directly proportional to the rate of reaction. We believe this due to the following theory: [IMAGE]The collision theory: This theory states that for a reaction to occur the reactant particles need to react with sufficient energy.

Rate of Reaction Between Marble Chips and Hydrochloric Acid. The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) is used. There are many variables that affect the rate of this reaction such as the following. 1.
Investigating the Rate of Reaction Between Marble Chips and Hydrochloric Acid I am investigating the rate of reaction between marble chips (calcium
Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different concentrations of acid reacting with magnesium in two separate experiments, which will hopefully prove this initial prediction. [IMAGE][IMAGE] During my science lesson I have learnt the following information that has enabled me to plan my investigation.
The Effect of Acid on the Rate of Reaction with Magnesium Aim: To find out how the concentration of hydrochloric acid affects the rate of reaction with magnesium ribbon. Hypothesis: I think that the lower the concentration of Hydrochloric acid, the slower the rate of reaction with Magnesium ribbon. The reason why is because there are less particles in the same volume so less collisions are possible every second, therefore less effective collisions will occur. Preliminary work: I did an experiment before to find out how the concentration of hydrochloric acid affects the rate of reaction with Sodium Thiosulphate. Preliminary work backs up this hypothesis.
