The Rate Of Reaction Between Magnesium And Hydrochloric Acid

Aim

My aim is to see how the rate of reaction between magnesium and
hydrochloric acid is affected by changing the length of magnesium.

Hypothesis

I predict that if the length of magnesium is high then rate of
reaction will be much more longer because if the length of magnesium
is more then it will take longer to dissolve and therefore it will
react for a longer time.

Apparatus
=========

o Measuring cylinders

o Boiling tube

o Ruler

o Stop Watch

o Magnesium ribbon

o 2 molar hydrochloric acid

o Water

Plan
====

First I will set up the experiment then I will put 15cm cubed of
hydrochloric acid and 15cm cubed of water inside the boiling tube. I
will then put in a 0.5cm long piece of magnesium into the tube and I
will start the stopwatch and I will see how long the magnesium reacts
for before dissolving in the solution.

The experiment will be repeated again on numerous occasions but the
length of magnesium will be changed. I will do this by adding 0.5cm to
the length of magnesium each time.

I will repeat the experiment in order to get some accurate results.
After repeating the experiments I will have two sets of results, I
will work out the average and then I will plot the graphs.

The way that my experiment will be made fair is that only one thing
will be changed and that is the length of magnesium but all the other
things that can have an effect on the outcome will be kept the same
e.g. temperature and volume of liquid. This experiment will be done at
room temperature therefore the temperature is the same all through the
experiment. The same concentration will be used through the
experiment. (The first experiment that I will do will look at the
effect different concentration has on the

- The Effect of Increasing Concentration of Hydrochloric Acid on the Rate of Reaction Aim: To investigate the effect of increasing the concentration of Hydrochloric acid on the rate of reaction. In gases and liquids, particles are in constant motion. It is clear that not all collisions are effective. Only small fractions of them seem to be 'successful' collisions. Particles in liquids and gases are moving at different speeds and colliding in different ways. Some collisions are 'head-on', while others are 'glancing' collisions....   [tags: Papers]

## Rates of Reaction - The concentration of hydrochloric acid and the rate of reaction with sodium theosulphate

- Rates of Reaction - The concentration of hydrochloric acid and the rate of reaction with sodium theosulphate Introduction During a chemical reaction, particles collide with each other. This collision causes certain bonds to break and new ones to be formed. A certain amount of energy is needed to allow a reaction to take place. This is called the activation energy; it’s the minimum quantity of energy that is required. There are certain factors that can affect the rate of reaction. These are surface area, temperature, concentration and catalysts....   [tags: GCSE Chemistry Coursework Investigation]

## Hydrochloric Acid's Effect on The Rate Of Reaction Between Hydrochloric Acid And Magnesium

- Hydrochloric Acid's Effect on The Rate Of Reaction Between Hydrochloric Acid And Magnesium The variables that could be used are: 1. Concentration 2. Particle size/surface area 3. Pressure (for reactions involving gas) 4. Temperature 5. Light 6. Presence of a catalyst. I decided to use the concentration of acid as my variable. I used 5 different strengths of hydrochloric acid. These strengths would determine the rates of reactions. I decided to measure the acid in millilitres....   [tags: Papers]

## Essay about Rate of Reaction of Dilute Hydrochloric Acid and Sodium Thiosulphate

- Rate of Reaction of Dilute Hydrochloric Acid and Sodium Thiosulphate To investigate the change in rate of reaction between DILUTE HYDROCHLORIC ACID and SODIUM THIOSULPHATE as the concentration varies. PLAN A chemical reaction takes place over a specific period of time i.e. which is the time for the reactants to be formed into the products. If the reactants take a relatively short time to form the products, the reaction is known as a FAST one. The RATE of that particular reaction is high. On the other hand, a reaction which takes a longer time is known as a SLOW reaction, and as a result is known to have a LOW rate of reaction....   [tags: Reaction Rates Chemical Reactions Essays]

- Rate of Reaction Between Marble Chips and Hydrochloric Acid To investigate the factors which affect the rate of reaction between marble chips and hydrochloric acid, with one in specific detail. Scientific knowledge: Marble chips erode when they are exposed to acid rain or pollution. Erosion is evident when you look at older marble buildings as in certain cases the erosion take a long time. It is more likely to occur in areas, where there is more pollution. This is because there are a greater number of industries in city than in the countryside....   [tags: Reaction Rates Chemical Reactions Essays]

## The Effect of Changing the Concentration of Hydrochloric Acid on the Rate of Its Reaction With Marble Chips

- The Effect of Changing the Concentration of Hydrochloric Acid on the Rate of Its Reaction With Marble Chips A reaction is when two particles (reactants) join to form a new product or products . A rate is a measure of how fast or how slow something is. Rate is a measurement of the change that happens in a single unit of time. The rate of a chemical reaction is how fast the reactants react. To find a rate of reaction you measure the amount of product given off by the reaction in a unit of time ....   [tags: Papers]

From these results two graphs will be plotted, one on the average time
and one on the Rate 1/t (X 10000).

Conclusion

From my results, the conclusion that I have reached is that the
prediction which I made was correct and that the bigger the length
magnesium the longer the reacts for. This is because if the length of
magnesium is more then it will take longer to dissolve and therefore
it will react for a longer time.

As you can see on the graphs that I have drawn, as the length
increases so does the reaction time this proves that the prediction I

Evaluation

The experiment which I completed was done up to a high standard and
the results I got were quite good and seemed reliable as they backed
up my prediction.

I think that the experiment was done in a very well because I didn't
get any irregular result.

If I had a chance to do the experiment, again I would make sure that I
was working with someone because when I did the experiment I had to
put magnesium in the solution and then start the stopwatch and this
made the results less accurate, but if I was working with someone the
results would have been more precise.

Another drawback was that when I was waiting for magnesium to dissolve
and stop reacting I was looking with my eyes so therefore sometimes
the results I got would not be fair. Fairness in an issue like this
can be found in a light sensor. The light sensor will pass through the
boiling tube and the solution and send the results back to the
receiver this would enable me to tell whether the magnesium was still
reacting.

Another thing was that when the liquids were being measured they were
not done accurately because there was a shortage of time so everything
had to be done quickly and this caused the results to be less precise.

Overall, I think that this was a good experiment and the best that
could have been done with the time and resources available.
