Aim
During this essay I bequeath be investigating if thaw limestone and changing the concentration of the acid go forth affect the enumerate of reaction. Â Â Â Â Â Â Â Â
Preliminary work
Before doing our main experiment, we will have to conduct         another experiment, to probe what concentration of acid we will have to use. We done this apply 0.1M, 0.5M and 1M of Hydrochloric acid, and 0.1g of powdered limestone, we used powdered limestone, as it would be a fairer test, I think this as all the particles of limestone will be roughly the same size, the particles have a larger scratch area than cubed limestone, therefore it will react the quickest. If you were to use cubed limestone it wouldnt be fair as no cube will be exactly the same size. In conclusion to this experiment, 0.5M of acid was the topper to use as it had the best measurable reaction epoch.
Equipment
The equipment we will be using during this experiment is:
*Goggles (to protect the eyeball from reactions)
*Measuring cylinder (to measure out the acid)
*Bunsen burner (to wake the acid to the right temperature)
*Test tubes (to hold first experiment in)
*Hydrochloric acid (the acid existence used)
*Powdered limestone (the substance being used)
*Triangular stand (to hold the Bunsen burner)
*Timer (to time the reaction)
*Thermometer (to record the temperature)
Diagram
Possible Variables
The possible variables are:
*Temperature of acid- this will determine how quickly the reaction happens e.g. the limestone reacts fast-paced or slower under a certain temperature. When the acid is heated, the particles gain
*Amount of Hydrochloric acid used
*Amount of limestone used
* grow area of limestone- this will determine how quickly the reaction will happen e.g. If the limestone is cubed or powdered
*Concentration of acid- this will determine whether the limestone dissolves faster or...
