Introduction

Chemistry Coursework. AIM: To investigate how the volume of Hydrochloric acid Affects the rate at which a reaction takes place. EQUATIONS: Magnesium+hydrochloric acid=magnesium chloride+hydrogen Mg+2HCl=MgCl2+H2 Method: I have been asked to produce a piece of coursework that measures the rate at which a strip of magnesium is dissolved by hydrochloric acid. ...read more.

Middle

First of all I got all of the following equipment plus the relevant safety equipment (goggles to protect my eyes and an apron to protect my body from splashing); * strip of magnesium * Hydrochloric acid * Measuring cylinder * Stopwatch * Beaker Once the equipment had been collected I set-up the experiment. ...read more.

Conclusion

I used 2cm lengths of magnesium for each experiment as I realised that when using smaller amounts of hydrochloric acid the magnesium would take too long to dissolve and it would be a waste of time. I decided against 1cm because I thought that maybe when larger quantities of hydrochloric acid were used the experiment would be over too quickly. ...read more.

    This method would be much more accurate as the computer would produce precise readings and almost perfect or perfect results. The computer could be used to measure the colour/ intensity change of the solution, as the solution changes the end point could be established.

    would be too small a quantity as the thermometer did not fit well into it. If not much of the thermometer is in the liquid then the temperature readings will be less accurate. I decided 150ml would be better suited to the experiment and would mean the thermometer would give a more accurate reading.
