Disappearing cross coursework

Gcse chemistry rates of reaction coursework this could be a problem because it could take a longer/shorter time for the cross to disappear if there is a bigger “layer” of solution •i will also make sure that i measure the same amount of sodium thiosulphate each time because otherwise it might affect the concentration of the reactants. In this experiment the effect of temperature on the rate of reaction between sodium thiosulfate and hydrochloric acid is investigated. Gcse chemistry rates of reaction coursework uploaded by anjelina qureshi •using the same pen to draw the cross because a different colour could show up better also different thickness of the pen could show up better •using the same piece of paper because graph paper could make the pen show up better than plain/lined paper.

Then we drew a cross onto a piece of paper and put an empty conical flask on top of the paper next, we poured the 25cm3 acid and 25cm3 thio into the conical flask and started the stop clock disappearing x experiment coursework about sodium thiosulphate and hydrochloric acid method, results, fair testing, evaluation included was marked. Disappearing x experiment coursework about sodium thiosulphate and hydrochloric acid method, results, fair testing, evaluation included add hydrochloric acid and sodium thiosulphate, and record the amount of time taken for the cross to disappear through the solution from the top of the flask.

10°c, the time taken for the cross to disappear is roughly halved it is not exactly halved each time, for example at 10 °c the time taken for the cross to disappear is 195 seconds and at 20°c the time taken for the cross to disappear is 107, which is roughly half of 195 but not quite.

Cross drawn on paper conical flask water stopclock method first of all we measured out 25cm3 acid and 25cm3 sodium thiosulphate then we drew a cross onto a piece of paper and put an empty conical flask on top of the paper disappearing x experiment coursework about sodium thiosulphate and hydrochloric acid method, results, fair. Disappearing cross reaction - sodium thiosulphate and hydrochloric acid. Disappearing cross experiment plan ==== i must produce a piece of coursework investigating the rates of reaction the rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction there.

Gcse chemistry coursework: investigating the rate of a reaction your task is to plan, and carry out, an experiment to discover how to change the rate the reaction between time how long it takes for the cross to disappear, and take the temperature of the mixture 5 wash out the flask thoroughly repeat the experiment using the.
