Apparatus: 50 cm 3 beakers, test tubes. They add 6,5 g of zinc granules to excess DILUTE sulphuric acid and measure the mass of zinc used per unit time. Rate Of Reaction With Zinc And Hydrochloric Acid. Therefore, we sought to test the duration of reaction of equal lengths Magnesium ribbons with reducing concentrations of hydrochloric acid. Introduction In this chemical reaction, the magnesium will dissolve in the hydrochloric acid to produce hydrogen gas. Place about 5cm depth of the acid in each of the five test tubes; Place a small piece of each of the three metals above. Hydrochloric acid, HCl(aq) – see CLEAPSS Hazcard HC47a and CLEAPSS Recipe Book RB043. Measuring Reaction Rates Name B I. In reaction of zinc with hydrochloric acid hydrogen gas is liberated. An experiment is carried out to investigate the rate of reaction when calcium carbonate is reacted with hydrochloric acid. Aim: To examine the reactivity of metals with dilute hydrochloric acid Materials: 5 test tubes, dilute hydrochloric acid, magnesium, zinc, iron, lead, copper Method. The diagram shows pieces of apparatus used to collect gases. Set I: 1 g of zinc powder and 20 cm 3 of 0.4 mol dm – 3 hydrochloric acid at room temperature. When these chemicals react they form a precipitate which makes the solution go cloudy. Analyzed our informations and datas to compare to other group's datas. Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction.Preliminary work Before doing our main experiment, we will have to conduct another experiment, to see what concentration of acid we will have to use. Set II: 1 g of zinc powder and 20 cm 3 of 2 mol dm – 3 hydrochloric acid at room temperature. Materials: Marble chips, 2 mol dm-3 hydrochloric acid, 0.1 mol dm-3 sodium thiosulphate solution, 1 mol dm-3 lead(ll) nitrate solution. Mg(s) + 2HCl (aq) → MgCl2(aq) + H2(g) In each experiment, the hydrochloric acid is in excess. Of the four acids which gave me valid results, the order of rate of reaction is therefore (slowest) Methanioc, Hydrochloric, Phosphoric, Sulphuric (fastest). In this experiment we tested the effect of concentration of HCl or Hydrochloric acid at which a piece of Zinc Metals dissolved. Science experiment on acid and carbonate reaction. 2 A student investigated the rate of reaction between dilute hydrochloric acid and aqueous sodium thiosulfate. Therefore, we sought to test the duration of reaction of equal lengths Magnesium ribbons with reducing concentrations of hydrochloric acid. From the results, you will be able to determine the order with respect to the acid. 1541 Words | 7 Pages. The Rate Of Reaction Between marble Chips and Hydrochloric Acid. Zinc is a metallic element that reacts with hydrochloric acid when it's in its elemental state. Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction.Preliminary work Before doing our main experiment, we will have to conduct another experiment, to see what concentration of acid we will have to use. Each experiment run will need 50 cm 3. The formation of In Experiment 1, 25 cm3 of 1.5 mol / dm3 hydrochloric acid were used. A chemist wishes to determine the rate of reaction of zinc with hydrochloric acid. Zn + HCl = H2 + ZnCl2 It is a single displacement reaction where - Zinc is oxidised (it becomes positive) and water is neutralized. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen … € The reaction produced a precipitate, which made the mixture turn cloudy.
