To measure the effect of concentration on the average rate of a reaction. It is a single replacement reaction where zinc replaces the hydrogen. Hypothesis: I believe that the most concentrated the HCl is, the faster the reaction will be. ... Zinc and Iron) Investigating Reactions of Metals with Acids. Answer Save. When hydrochloric acid and zinc are combined, they create hydrogen gas and zinc chloride, which is a salt. Measure out 5 mL of 0.01M Hydrochloric Acid with the Graduated Cylinder and pour it into a test tube using a funnel 2. Zinc chloride that only grows on the north side of trees. Weigh the zinc metal pieces and place them in a test tube $ 2. 14. Let’s examine the example of the interaction between zinc and hydrochloric acid. In the zinc and hydrochloric acid experiment the learners collect gas in a balloon. Place the zinc granules in the flask, loosely fit the stopper carrying the delivery tube and clamp the flask so that the end of the delivery tube is well below the surface of the water in the trough. Keep an eye on all of them at the same time and note any changes and the relative rate of evolution of gas bubbles - which is a crude measure of the relative speed of reaction of the metal with the acid. So I did the experiment and everything, but I was just wondering how it would have turned out if I'd used double the amount of zinc, or double the amount of hydrochloric acid? AIM: The purpose of this experiment is to find out what determines the speed of a reaction (in this case, between Hydrochloric Acid and Zinc). The whole purpose of this experiment is to determine wether or not the amount of the zinc and or hydrochloric acid effects the out coming percent of the solution after under going chemical reaction. Would it affect the amount of hydrogen gas produced at all? NaOH) by their reaction with Litmus solution (blue/red) Zinc metal Solid sodium carbonate Materials Required Test tubes, test tube stand, test tube holder, cork, droppers, boiling tube, match-box, burner, […] Zinc is a heavy metal compared with lithium, for instance, so the bubbles don’t rise to the surface.. Look here for some awesome experiments with zinc.. Reaction of zinc and hydrochloric acid. Seriously. Do not light the gas in the balloon or allow it to be near flame. Detailed revision notes on the topic Experiment: Metal Reactivity with Acids. HCl) and bases (dil. 1 Answer. The speed of the reaction also depends on the mass of the Zinc used in the experiment. Measuring reaction rates Aim. There will be an explosion. Observe $ 3. To perform this experiment, a scientist begins by adding a small amount of hydrochloric acid … When zinc metal reacts with dilute hydrochloric acid, the gas evolved (a) supports combustion (b) turns lime water milky (c) bums with a pop sound (d) has a pungent odour. Written by teachers for the Edexcel IGCSE Chemistry course. Drop 1 strip of zinc in the test tube and record the time it takes for the zinc metal to completely dissolve 3. The experiment is extremely easy to do, simply add similar sized small portions of the metal to a few cm 3 of cold dilute hydrochloric acid. Ok. Measure out 50 cm 3 of the dilute hydrochloric acid supplied, remove the delivery tube, and add the acid to the zinc granules in the flask. Zinc and Hydrochloric acid experiment question? Zn + HCl = H2 + ZnCl2 It is a single displacement reaction where - Zinc is oxidised (it becomes positive) and water is neutralized. When zinc reacts with dilute hydrochloric acid (a) the surface of zinc becomes brighter (b) the surface of zinc becomes black and dull (c) the metal turns into powder CBSE Class 10 Science Lab Manual – Properties of Acids and Bases EXPERIMENT 2(a) Aim To study the properties of acids (dil. Pour some hydrochloric acid over the zinc pieces. Procedure $ 1. 5 mL of 1.0M Hydrochloric Acid; 6 strips of zinc metal; Funnel; Safety Goggles; Timer; Procedure: 1. It is a reduction-oxidation reaction where one of the reactants loses oxygen and the other one gains. Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g) As you can see, zinc (mossy or otherwise) will react with hydrochloric acid to make a solution of zinc chloride and hydrogen gas, which will be given off.
