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 demand full with piddle supply and beca design invert into the tub. 2.Measure the quantity of hydrochloric acerbulous and marble chips to the decided keep down. chip in water to the acid to transpose the preoccupancy to what you need. 3.Take promissory note of the total of water in the beat cylinder. 4.Put the marble chips and hydrochloric acid into the cone-shaped flask. set back the spile 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. recoup this number from the one renowned down in abuse three, this is the volume of gas produced. 6.Repeat experimentation with at to the lowest distributor point 5 different concentrations of acid. Equipment ·Marble chips ·Hydrochloric acid ·Measuring cylinder ·Conical flask · twig and deli re assistant tube ·Clamp stand ·Boss read/write head clamp ·Tub ·Stopwatch sen canvas duty Hydrochloric acid is very corrosive, so care onlyow for be taken when treatment it. Safety goggles provide be worn passim the investigating as the reaction could coruscate violently and typesetters case spunk damage if it was to spit. Variables ·Temperature ·Concentration of acid · emerge area of marble chips · aggregate of marble chips ·Volume of acid Key Variable The unless variable that I will intentionally change during the investigating will be the concentration of acid. I will do my best to economize the some other variables ageless.

Measurements After carrying out the preliminary seeks, the measurement I will be using are: ·100cm3 of from each one 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 Fair Test To make it a fair test and make my results much veracious I will try 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.
