Science coursework: rate of reaction the aim of the experiment: in this experiment i will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction to find this out i will react different concentration of hydrochloric acid and magnesium, from there i will monitor the gas (hydrogen) produced and analyse. Hi guys i am new to this forum but i needed some help and thought i could get it here i need a piece of coursework for the rate of reaction between sodium thiosulfate and hydrochloric acid. The concept of strong and weak strong acids in aqueous solution, a strong acid [acid: a corrosive substance which has a ph lower than 7 acidity is caused by a high concentration of hydrogen ions] is one that completely dissociates (splits up) into ions.
Chemistry coursework planning aim: to find the effect of concentration of thiosulphate on the rate of reaction between sodium thiosulphate and hydrochloric acid. 3 cm of magnesium ribbon typically has a mass of 004 g and yields 40 cm 3 of hydrogen when reacted with excess acid 50 cm 3 of 1m hydrochloric acid is a six-fold excess of acid in this reaction, the magnesium and acid are gradually used up. Alternatively, you could vary the concentration of the acid using 04m, 08m 12m, 16m and 2m the more concentrated the acid, the more frequently the acid particles collide with the marble and therefore the faster the reaction.
Our objective is to study the effect of concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid the theory what is chemical kinetics for any chemical reaction, its feasibility and extent of reaction are very important the feasibility of a reaction can be predicted by thermodynamics and the extent can be. Reaction rate and concentration f the above diagram illustrates how you can investigate how varying the concentration of hydrochloric acid gcse chemistry. How can the answer be improved.

Pour hydrochloric acid into the petri dish to a depth of about 5 mm using forceps, place the magnesium ribbon into the petri dish the magnesium reacts with the acid, producing visible bubbles of hydrogen gas. Catalyst and of course a change in concentration all of these factors affect the threshold energy which is simply the minimum amount of kinetic energy required to start a reaction.
