Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate. To do this I would make sure that: The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a cover letter for customer service advisor position reaction. Dependent variables are not controlled by the experimenter. I tucked in my tie and shirt, and took off my blazer. In this investigation I will use the following word equation: The bars of 1M and 2M overlap and this shows that there is no real difference.
Free Essays words 1. I think that my method for my investigation is easy to follow. Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. Papers] Free Essays words 5. Skip to main content. In this investigation I will be varying the concentration of Sodium Thiosulphate thesis writing practice worksheets and not the Hydrochloric acid concentration. My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I made.
Papers] Research Papers words 3. For example, rusting is a slow reaction; it has a low rate of reaction.
I then drew up graphs for my results Data Concentration Test Test 2 Test 3 M 1 s s s 1 wcid 3 4 5 Table 1: I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3. According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time. In a more concentrated solution there are more particles so collisions occur more frequently Recent updates The rate of reaction is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6.
I wrote down my results and then moved on to the next concentration of sodium thiosulphate. Enter the email address you signed up with and we’ll email you a reset link. This can be done by: Background Knowledge The thiosulphate of a reaction can be speeded up by increasing the temperature; at a higher gcse the particles move faster and collide more often, as a result of this the reaction speeds up. This shows that my data is quite accurate.
The reaction that occurs produces sulphur dioxide, water and sodium chloride. The state symbol for sulphur dioxide is aq not g because it is dissolved in water as its original state would be too toxic and corrosive for me to use safely. I could have use a colorimeter to identify colour changes in the products. The bars of 1M and 2M overlap and this shows that there is no real difference.
Hydrochloric acid is colourless, poisonous and highly acidic. Heavier particles move more slowly than light ones at a given temperature. I drew 6 different graphs for this investigation. This is supportive of my conclusion.
Investigating The Rate Of Reaction Between Sodium Thiosulphate And Hydrochloric Acid
Oops, we could not find the requested page. The points in the top right are quite far down so this shows a negative correlation. These chemicals are perfect for my investigation because they are both clear and colourless.
This could have happened because courseworm human error, wrong calculations or simply not enough activation energy on that particular concentration. Research Papers words 4. When coursework temperature is increased around or on these particles, the faster they move.
The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. It is measured by dividing 1 by the time taken for the reaction to take place.
The rate of hgdrochloric is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6. The page you are looking for might have been removed, sodiun its name changed, or is temporarily unavailable.
The bars for 3M, 4m and 5M do not overlap. This good because it shows that for every increase in concentration is a decrease in rate of reaction.
There is five factors which affect the beyween of a reaction, according to the collision theory of reacting particles: This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and at random in all the space available, in solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask. These two acids react well with the right materials. This is the reaction I will be considering:
