Rates Of Reaction Investigation Report

4. While the reaction was still occurred, lighted a wood splint and quickly placed the burned splint in the mouth of the test tube. Do not put the burned splint into the acid solution.

This website was used on October 3, 2014 to help develop a better understanding of collision theory in order to explain the various factors affecting the rate of reaction.

4. Both test tubes appear red with the acetic acid with the methyl orange. This indicates that the equilibrium lies toward the acid.

How concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate Chemistry Coursework How Concentration Affects a Reaction Aim: The aim of this experiment is to find out how concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate. Introduction: This experiment will be carried out by drawing a cross on a piece of paper and mixing hydrochloric acid and sodium thiosulphate together to see if the cross disappears. The concentration of hydrochloric acid would change every reaction to show that concentration effects a reaction.

Three factors that can affect the rate of reaction are temperature, pH and the salinity.

The aim of the experiment will be to investigate how varying water temperatures influence the time of a chemical reaction, in this case being, a combination of Sodium Thiosulfate and Hydrochloric Acid.

Purpose: The purpose of this experiment was to observe the many physical and chemical properties of copper as it undergoes a series of chemical reactions. Throughout this process, one would also need to acknowledge that even though the law of conservation of matter/mass suggests that one should expect to recover the same amount of copper as one started with, inevitable sources of error alter the results and produce different outcomes. The possible sources of error that led to a gain or loss in copper are demonstrated in the calculation of percent yield (percent yield= (actual yield/theoretical yield) x 100.

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. This is basically how hard and how often particles collide with each other. The more and harder they collide, the faster the reaction time will be.

Table 4.14 and Table 4.15 shows the readings for the test conducted at pH8. It can be seen that there was very

The process was then repeated for the second reaction but using 1.00-mL of a 6.00-M phosphoric acid solution and 4.00-mL of a 3.00-M sodium hydroxide solution.

By using acid-base titration, we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein's color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of the range of phenolphthalein.. The methyl red indicator and the phenolphthalein indicator were unsuitable because their pH ranges for their color changes did not cover the equivalence points of the trials in which they were used. However, the

The main objective of this lab experiment is to understand the connection between quantities of reactants and the amount of products produced by a chemical reaction. A stoichiometric ratio can be defined as the mole ratio of the reactants, as determined by the coefficients in the balanced chemical equation. There are several ways to do this, but each starts with a balanced chemical equation so that the stoichiometry of the reaction is known. In this lab, students used two methods, the job’s method and the mole-ratio method, to determine the mole-ratio number. Also, it is important to be able to calculate which reactant is the limiting reactant because the limiting reactant will determine the amount of product that can be produced during a reaction.

I predict that out of the 20 solutions that we are going to be testing, about 6 of them will be an acid, 3 will be neutral and 11 will be a base.

This is a fair test because the only thing that is changed is the drop
