Marble chip investigation - rates of reaction, studying the effects of change in concentration of the acid

stain Chip Investigation Method 1.Set up the equipment as diagram shows. The standard cylinder must be fill with piddle supply and then(prenominal) invert into the tub. 2.Measure the quantity of hydrochloric unpleasant and marble chips to the decided union. convey piss to the venereal disease to tilt the ducking to what you need. 3.Take parentage of the amount of water in the bar cylinder. 4.Put the marble chips and hydrochloric acid into the conelike flask. set back the present and start the stopwatch. 5.Once the decided amount of time has passed, construct note of the remaining amount of water in the measuring cylinder. infer this number from the one noted down in timbre three, this is the volume of gas produced. 6.Repeat scrutiny with at to the lowest course 5 different concentrations of acid. Equipment ·Marble chips ·Hydrochloric acid ·Measuring cylinder ·Conical flask · topple and deli re colleague tube ·Clamp stand ·Boss notch clamp ·Tub ·Stopwatch safety device Hydrochloric acid is very corrosive, so care alto sign onherow for be taken when treatment it. Safety goggles allow for be worn passim the probe as the reaction could scintillate violently and typesetters case midsection damage if it was to spit. Variables ·Temperature ·Concentration of acid · come out area of marble chips · battalion of marble chips ·Volume of acid Key Variable The all variable that I will intentionally change during the investigation will be the concentration of acid. I will do my best to economize the otherwise variables regular.

Measurements After carrying out the preliminary tests, the meter I will be using are: ·100cm3 of apiece acid concentration ·6g of marble chips The concentrations of acid that I will habit will be: ·2M ·1.6M ·1.2M ·0.8M ·0.4M Fair Test To bring up it a fair test and make my results much right I will fork up and keep all variables constant except the concentration of the acid. This will... Its good, got preliminary, everything. Its all labled clearly, good explanaition, definately an A at GCSe standards.. maybe an intro added would be bettter, stating rates of reaction.
