Aim The aim of my investigation is to find out how the rate of the reaction bettween diloute hydrochloric acid and marble chips will be affected by chngeing things, for example more surfice area expose to the dilouted hydrochloric acid. And to report about the findings I made. Investigation Planning Method First of all I will need to get out the following pieces of equipment, a gas syringe, a chronicle flask, a burette, a clamp, a 10cm cubed measuring cylinder, a set of scales, a beaker, a stop watch, dilute hydrochloric acid and medium size marble chips, we will also need a bunson burner a tripod when I am heating up the diloute hydrochloric acid. The experiment will be set up as show below in the diagram (for most of the experimnts). I will weigh out exactly or as close as possible to 1.5 grams of medium sized marble chips. Using a burette I will measure out exactly 25 cm cubed of dilouted hydrochloric acid in a 10cm cubed measuring cylinder. I will put the chips into the flask with the acid and immediately place the gas syringe bung over making sure I lose as little gas as possible.
