The second reaction that will be studied is the reaction of magnesium oxide with aqueous hydrochloric acid. Syringes should not be allowed to become wet, or the plungers will stick inside the barrels. 3. Importantly, suitable acid-base indicators can be used to detect the end of the reaction accurately. For instance hydrogen bubbles block magnesium surface or blow the magnesium to the surface of the acid solution therefore, slowing down the reaction. Even if you don't want to stud. This is because the hydrogen ions (H+) from the acid I have a large binding surface on magnesium metal but later, the surface area diminishes due to other factors in the reaction. Hydrochloric acid is a corrosive liquid. 3. The quantity of Magnesium metal used will be held constant by way of using equal lengths of Magnesium ribbons and equivalent weights (in grams) of powdered Magnesium metal.All the reaction will be carried out under a constant temperature (room temperature of 25.

(a) Write a balanced equation for the reaction of zinc and dilute hydrochloric acid. Students follow the rate of reaction between magnesium and the acid, by measuring the amount of gas produced at 10 second intervals. However the acid is in excess, so it is mainly the loss of magnesium (surface area becomes smaller) that causes the change in the rate. The remaining ions combine to produce the salt of neutralisation. The reaction that will take place when the magnesium will be added to hydrochloric acid will produce magnesium chloride and hydrogen gas, written in the form Mg(s) + 2HCl(aq) --> MgCl 2 (aq) + H 2 (g)[ CITATION Gre \l .
