Reaction of metals lab

For example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second. There is also a danger of hot material spitting out of the container. Choose one of the metals that reacts rapidly with the acids, and in a clean test-tube add a piece of this metal to a 2—3 cm depth of one of the acids. Be very careful not to knock the tripod supporting the basin. Teaching notes student sheet available with this resource and get the students to work each question after observing the reaction. For this experiment, the four metal powders given are magnesium, zinc, aluminium and iron. Turn off the Bunsen burner before the solution boils. If there is any doubt about the safety of this step, the teacher should first lift each beaker down onto the heatproof mat, using a thick cloth or wearing suitable thermal protection gloves, before the students add the zinc pieces. Safety is particularly relevant to younger students. Pour approximately 5 cm of 2M Hydrochloric Acid into a test tube. Complete steps 2 — 9 using the magnesium this time. If crystals begin to appear, e. Press enter to begin your search Reactivity of Metals: Lab Report No Comments Reactivity of Metals Experiment Aim: To investigate and see the reaction of four metals- magnesium, zinc, aluminium and iron with copper sulphate to find out which one is the most reactive and which one the least reactive. When the volume has been reduced by about half, dip a glass rod in the solution and then hold it up to cool.

The metal powder easily forms a compound with the non-metal ion of the compound and more energy is given out. Turn off the Bunsen burner before the solution boils.

reactivity of metals with hydrochloric acid lab answers

When a displacement reaction occurs, heat energy is given out which means that the reaction is exothermic. The same applies to moving the evaporating basin before pouring its contents into the crystallising dish. HCl Final Temp.

Reaction of metals with acids experiment

Repeat steps 1 — 9 with Al, Fe, and Cu. Safety is particularly relevant to younger students. This collection of over practical activities demonstrates a wide range of chemical concepts and processes. Record visual observations ex. Add more zinc until no more bubbles form. For example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second. Moreover, it will be the hottest when the reaction between magnesium and copper sulphate takes place.

Do not continue to heat beyond the point when crystals start to appear on the top edge of the solution. Moreover we also see that the reaction with magnesium took the shortest time to complete.

Reaction of metals with water

It is because gold, silver and platinum are chemically very un-reactive and retain their shiny appearance. For this experiment, the four metal powders given are magnesium, zinc, aluminium and iron. Clean a piece of zinc with the steel wool until it is shiny. Un-reactive metals such as gold do not react with hydrochloric acid HCl , no matter how concentrated the acid is. Press enter to begin your search Reactivity of Metals: Lab Report No Comments Reactivity of Metals Experiment Aim: To investigate and see the reaction of four metals- magnesium, zinc, aluminium and iron with copper sulphate to find out which one is the most reactive and which one the least reactive. Record visual observations ex. However, more reactive metals react to form a metal chloride or a salt and hydrogen gas when added to HCl. The rise in temperature will become lesser in the order of reactivity and therefore the reaction between rion and copper sulphate will be the least reactive and will take the longest time for the reaction to complete. Theory: The reaction rate or rate of reaction for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place. For example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second. Teaching notes student sheet available with this resource and get the students to work each question after observing the reaction. This happens because the compound on the reactants side is quite unstable and thus breaks up easily and so much energy is not used up. Moreover we also see that the reaction with magnesium took the shortest time to complete. Transfer the filtrate into an evaporating basin.

If nothing happens, you may need to try again.
