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

Marble Chip Investigation Method 1.Set up the equipment as diagram shows. The standard piston chamber must be fill with piddle supply and then invert into the tub. 2.Measure the quantity of hydrochloric erosive and marble chips to the decided amount. Add water to the demigod to interpolate the concentration to what you need. 3.Take demean of the amount of water in the metre cylinder. 4.Put the marble chips and hydrochloric acid into the conical flask. set back the topple 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. figure this number from the one noted down in footfall three, this is the volume of gas produced. 6.Repeat experiment with at to the lowest decimal point 5 different concentrations of acid.

Safety goggles give be worn passim the investigation as the reaction could fizz violently and typesetters case spirit damage if it was to spit. variants ·Temperature ·Concentration of acid ·Surface area of marble chips ·Mass of marble chips ·Volume of acid Key Variable The only variable that I will intentionally transpose during the investigation will be the concentration of acid. I will do my best to economize the other variables constant.

Measurements After carrying come out of the closet the preliminary tests, the measu rement I will be utilise are: ·100cm3 of e! ach acid concentration ·6g of marble chips The concentrations of acid that I will use will be: ·2M ·1.6M ·1.2M ·0.8M ·0.4M unclouded Test To shoot it a fair test and make my results much accurate I will try and hold open all variables constant except the concentration of the acid. This will... Its faithful, got preliminary, everything. Its all labled clearly, good explanaition, definately an A at GCSe standards.. maybe an intro added would be bettter, stating place of reaction.
