Step two, measure 15 mL of hydrochloric acid into beaker. We also predict that reaction of powdered Magnesium metal with highest concentration of hydrochloric acid will take the shortest duration of reaction. A table of results showing HCl-Magnesium powder reaction duration (seconds) in reducing concentration, Graph magnesium + hydrochloric acid magnesium chloride + hydrogen. Therefore, considering concentration factor and surface are factor of reactants it is evident that the rate reaction curve trends would not be linear as expected, but rather exponential. Zinc will also react with hydrochloric acid like magnesium. Measure 40 ml of 3M HCl using a clean dry measuring cylinder and pour into a clean 100 ml conical flask. The remaining ions combine to produce the salt of neutralisation. 50 cm 3 of 1M hydrochloric acid is a six-fold . Each balloon has a different amount of Mg in it. 2. Measure and record the starting temperature of the acid. Contact: Randy Sullivan,smrandy@uoregon.edu. Concentration of HCl (M) 3.0. Remember to use proper notation and formatting. High concentrations imply that more reacting molecules are at high proximity to each other therefore intermolecular collisions are frequent therefore forming products frequently. 5.6 The rate and extent of chemical change, The units of rate of reaction may be given as g/s or cm3/s. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Identify type of reaction, predict the products, and balance. Even if you don't want to stud. Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) -->MgCl2(aq) + H2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas. For the 10 cm magnesium metal used, there was slight variation in weight. Ammonia is a weak base that reacts with hydrochloric acid, forming a compound called ammonium chloride. These revision notes on reactivity series of metals experiment observations should prove useful for the new AQA, Edexcel and OCR GCSE (9-1) chemistry science courses. Mrs V reacts magnesium with hydrochloric acid and tests the gas produced. For example: \[ Mg + H_2SO_4 \rightarrow MgSO_4 + H_2\] The duration of reactions were recorded as shown in tables 2 and 3 below. But when reaction proceeds, you can see white precipitate dissolves and gives a colourless aqueous solution. The net ionic equation for this reaction is.
