Rate of Reaction Between Marble Chips and the Varying Concentrations of Hydrochloric Acid Planning Before starting the experiment I had to work out how much marble chips would be needed and how much HCl would be needed. I decided that 20 grams of marble chips would be needed and I measured this on a pan balance. The chips would have to be of medium size as from a previous experiment done in class I realize that changing the surface area of the marble chips would change the rate of reaction. I then used 100 cm3 of HCl and this would be the only variable that I will change. I decided to use the concentrations of 0.5M, 1.0M, 1.5M and 2.0M (1mole/dm). To make these different concentrations I added different proportions of distilled water to the 2 molar HCl. For the 2M solution I left the HCl alone, for the 1.5M solution I put...
