Oliver Burke 10D Chemistry Coursework The Weathering Of Durham Cathedral (The rate of reaction between Calcium carbonate and Nitric Acid) ? Important factors in this investigation: ? Temperature of the experiment's surroundings ? Concentration of acid ? Surface area of marble chips ? Amount of acid used ? Mass of marble chips used I have chosen to find out if changing the concentration of acid will affect the rate of reaction and if so how. ? How will I make it a fair test? To make it a fair test I will keep all factors the same except the concentration of acid throughout the experiment. (Temperature of the experiment's surroundings, Surface area of marble chips, amount of acid used and mass of marble chips.) ? What are the key factors in this experiment and how will I control them? I will use marble chips of the same surface area (medium sized chips (6-7mm)) throughout the experiment, if I were to differ...
