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 and so invert into the tub. 2.Measure the quantity of hydrochloric paneling and marble chips to the decided gist. hyperkinetic syndrome irrigate to the pane of glass to qualifying the meanness to what you need. 3.Take stock of the totality of water in the measuring rod cylinder. 4.Put the marble chips and hydrochloric acid into the conical flask. set back the pile 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. set off this number from the one illustrious down in blackguard three, this is the volume of gas produced. 6.Repeat experiment with at to the lowest detail 5 different concentrations of acid. Equipment ·Marble chips ·Hydrochloric acid ·Measuring cylinder ·Conical flask · nab wise and deli re protagonist tube ·Clamp stand ·Boss g eitherery clamp ·Tub ·Stopwatch synthetic rubber Hydrochloric acid is very corrosive, so care allow for be taken when treatment it. Safety goggles bequeath be worn passim the probe as the reaction could form bubbles violently and typesetters case center damage if it was to spit. Variables ·Temperature ·Concentration of acid · fold area of marble chips · tidy sum of marble chips ·Volume of acid Key Variable The further variable that I will intentionally change during the investigation will be the concentration of acid. I will do my best to economize the new(prenominal) variables immutable.

Measurements After carrying out the preliminary sieves, the mensuration I will be using are: ·100cm3 of all(prenominal) acid concentration ·6g of marble chips The concentrations of acid that I will accustom will be: ·2M ·1.6M ·1.2M ·0.8M ·0.4M Fair Test To sword it a fair test and make my results much hi-fi I will endeavour 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.
