Investigating Reactions: This investigation is to discover how certain factors can affect the rate of reaction between limestone (calcium carbonate) and hydrochloric acid (2m acid). Plan There are many things that can be varied such as: Temperature Concentration of acid Surface area Mass of CaCO? Time Amount of 2HCL Adding catalysts In my experiment I have chosen to investigate how temperature affects the rate of reaction between CaCo? + 2HCL. I will determine the rate by measuring the amount of CO² produced in this reaction against time, and how different temperatures affect this. Although this is the variable I wish to change, I must keep everything else the same in order to ensure a fair test. These things are: Amount of acid (50cm³) Mass of CaCO? (5 grams) Time to measure reaction (5 minutes- to ensure the experiment lasts a sufficient time for results to be taken) Concentration of acid Surface area of calcium carbonate (small chips) Apparatus used - Thermometer - Conical...
