In this experiment the effect of temperature on the rate of reaction between sodium thiosulfate and hydrochloric acid is investigated. Investigate what happens to the rate of reaction when the concentration of sodium thiosulphate is altered in the reaction between sodium thiosulphate and hydrochloric acid rates of reaction investigation aim the aim of this coursework is to investigate what happens to the rate of reaction when the concentration of. I couldn't figure out the concentration of the hydrochloric acid used, but the times for the appearance of the sulfur cloud (disapperance of the cross) were given the range is between 20 s and 5 min i'd probably go with the 2 m hcl for safety reasons and perform the experiment with the thiosulfate. The rate of reaction between sodium thiosulphate and hydrochloric acid – chemistry iaa although, the anything that is highlighted in yellow is parts of the experiment in which we made it reliable: 1) place a 11) measure out the appropriate volumes of hydrochloric acid and sodium thiosulphate as in steps 2 and 3. Free essay: to do our experiment we will use: å¸ sodium thiosulphate å¸ water å¸ hydrochloric acid å¸ a beaker å¸ a stop-clock å¸ a measuring cylinder å¸ a.
The variable will be the amount of sodium thisolphate i use each time which will decrease by 10 cm3 each time when i repeat the experiment i will identify i will change the concentration of sodium thiosulphate (decreasing the concentration of the substance in solution means that there will be fewer particles per cm3). The reaction: when sodium thiosulphate reacts with hydrochloric acid sulphur is produced the sulphur forms in very small particles and causes the solution t. Turbidity sensor – measuring cylinder (10 ml) – beaker (100 ml) – 10 ml of hydrochloric acid hcl (01 m) – 10 ml of sodium thiosulphate na2s2o3 (01 m) procedure • connect the turbidity sensor to the input 1 of your interface • open coach 6 activity 'rate and order of reaction' • let the students setup the experiment.
Change so i do a better main experiment the first preliminary trial my first preliminary trail was to see if the surface area of a reactant affects the rate of reaction i tested my theory by measuring the time it takes for sodium thiosulphate pellets, to react with the hydrochloric acid i did this twice with different sizes of pellets. Rate of reaction - sodium thiosulphate and hydrochloric acid extracts from this document introduction sodium thiosulphate coursework introduction i have been asked to investigate the effects different factors such as concentration and temperature have on the rate of reaction the rate of reaction is the loss rate of a. Free essay: by doing this it is changing the concentration i am not going to carry out an experiment using 0ml sodium thiosulphate, 10mls hydrochloric acid.
The rate of a reaction between hydrochloric acid and sodium thiosulphate aim: i am going to investigate the effect of changing the concentration of sodium thiosulphate on the rate of the reaction between hydrochloric acid and sodium thiosulphate prediction: i predict that as the concentration of the sodium. Flask as you add 10cm3 of hcl and start the stopwatch 4 watch the solution as it clouds over once the cross has disappeared stop the clock 5 record the time in a results table 6 repeat the above steps for the other concentration of sodium thiosulphate repeat the experiment 3 times for each of the. The hydrochloric acid - sodium thiosulphate reaction depends on the time for a certain amount of sulphur precipitate to form and obscuring a marked black x on white paper briefly explain how the method can be used to measure the speed - the results of the first few minutes is usually the most crucial - you can discuss.
Disappearing x experimentintroductioni am going to investigate the rate of reaction between sodium thiosulphate (thio) and hydrochloric acidhydrochloric acid + sodium thiosulphate sodium chloride + water + sulphurthe reactants are both colourless. Effect of concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid in this experiment, the reaction is carried out by mixing the reactants in a conical flask, and placing the conical flask on the top of a piece of white paper that has a cross mark on it before the reaction starts, the mark is clearly.
