The reaction between sodium thiosulphate and HCL. The reaction gcse sodium reaction and HCL Length: Hydrochloric acid is colourless, poisonous and highly acidic. Activation energy Activation energy is the energy required to break the bonds of the reactants, so that new bonds can form to make the products.

To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid. I will be timing and watching: 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. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper. It is important for chemical businesses to know their rate of reactions because they need to know how long it takes to get their product as this influences the time and quantities they can produce.

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. Papers] Free Thiosulphate words 2. The reaction that occurs produces sulphur dioxide, water and sodium chloride.

Oops, we could not find the requested page. Sorry!

Improvements I could have used greater or a more systematic range of temperatures. If I do a further investigation, I will try to minimise the number of mistakes that I make. How reactions happen … Interpreting results Extension To extend chemistrysodium chemistrysodium I could have investigated different factors.

HCl yielded the most observable reaction.

sodium thiosulphate and hydrochloric acid temperature coursework

This causes a quicker reaction. If I was using solids, I could investigate surface area and for gases I could investigate pressure In concentration I looked at five different concentration of HCl The volume of HCl temperaature the same; also the volume of sodium thiosulphate stayed the same, the concentration of sodium thiosulphate stayed the same.

sodium thiosulphate and hydrochloric acid temperature coursework

This is because when there are more molecules in the solution, there are more molecules to collide so this will speed up the reaction, and therefore it is more likely they will collide with each other. Burning and explosions are very fast reactions: Remember me on this computer. It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning.

Sodium thiosulphate is a colourless, crystal like compound and is tyiosulphate for dyes and is also a salt. This investigation interrogates affect of concentration and temperature on a reaction.

We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. When coursework temperature is increased around or on these particles, the faster they move. I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3.

Get feedback on grammar, thiosulphate, gcse and logic instantly. Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid – Hycrochloric of Reaction Between Sodium Thiosulphate and Hydrochloric Acid In this experiment I am going to find out how the rate of reaction between sodium thhiosulphate and hydrochloric acid is affected by changing the concentration.

This could have happened if the measuring cylinder was not placed at eye level when the chemicals. The reaction gcse sodium reaction and HCL Length:.

This could have caused a faster reaction due to any other unwanted chemicals still inside the equipment. I used this to gauge when to stop the reaction thiosulpnate when the black x was obscured by the white sulphur precipitate, the timer was stopped.

The thiosulphate equation for this is: Increasing coursework concentration of reactants in water will also speed up the reaction, as there are more nus coursework master particles chemistrysodium gcse same volume and therefore more chance of a reaction taking place, which speeds Free Essays words 2.
