Free hydrochloric acid papers, essays, and research papers. The effect of temperature on the rate of reaction between sodium thiosulphate and hydrochloric acid - the effect of temperature on the rate of reaction between sodium thiosulphate and hydrochloric acid i predict that as the temperature is increased the rate of reaction will increase. Procedure $ 1 weigh the zinc metal pieces and place them in a test tube $ 2 pour some hydrochloric acid over the zinc pieces observe $ 3 allow the zinc d hydrochloric acid to set over night to make sure that the reaction reaches completion. Sodium thiosulphate and hydrochloric acid essay sample to investigate the effects of change in concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid.
Essay about chemical reaction and reaction rate carbonate and hydrochloric acid extracts from this document introduction calcium carbonate and hydrochloric acid surface area affecting the reaction rate introduction in this experiment calsium carbonate (caco3) will be put into a flask and then mixed with hydrochloric acid (hcl. Hydrochloric acid - sample essay from the raw data above i can see that all of the antacids tested had a neutralising effect on the hydrochloric acid the speed of the change in ph can be calculated by using the formula stated above and the raw data collected whilst performing the experiment. This is because the larger the surface area, the more particles that are in contact with the acid at any one time, so it will be able to react faster i might also use different strengths of acid to see whether the stronger the acid is, the faster the rate of reaction.
Hydrochloric acid solution 2 m cas number: 7647-01-0 synonym: hydrogen chloride solution linear formula: hcl find saj-13-1690 msds, related peer-reviewed papers, technical documents, similar products & more at sigma-aldrich. Hydrochloric acid solution 20 n cas number: 7647-01-0 ec number: 231-595-7 linear formula: hcl find sigma-h3037 msds, related peer-reviewed papers, technical documents, similar products & more at sigma-aldrich. ) 0conclusion i conclude that my predictions that the hotter the acid, the faster the rate of reaction, because the particles move faster and collide more at higher temperatures, and the more marble chips there are, the faster the rate of reaction, because there is more marble for the acid to react with to be true. The independent variables: the concentration of hydrochloric acid used and the surface area of the magnesium metal used the controlled variables (constants): the quantity of the magnesium for each test will be held constant.
We will write a custom essay sample on calcium carbonate and hydrochloric acid specifically for you for only $1638 $139/page. I will then calculate the rate of reaction between the marble chips and hydrochloric acid by measuring how much the levels of water in cmi drops every 10seconds so that it is a fair investigation i will make sure that i always start with 50cmi of water in the burette, and 1000cmi of acid in the beaker. Science coursework – what factors effect the rate of reaction between magnesium and hydrochloric acid background knowledge there are four factors that can affect the rate of reaction and they all rely on the collision theory.
In the strong acid-weak base titration, 0 1 m ammonium hydroxide ( nh4oh ) was titrated with 0 1 m hydrochloric acid ( hcl ) 2 drops of phenolphthalein were added as indicator into the conical flask which contains 25ml of hydrochloric acid, the mixture in the conical flask was colourless. Open the tap and release 10ml of hydrochloric acid 200 m into the conical flask containing dilute sodium thiosulfate 7 when the cross fully disappears, immediately stop the watch and record the time taken for the cross to disappear.
