This is an excellent chance to refine observation skills and use the vocabulary from the day before, describing the aluminum as "lustrous" instead of "shiny". In this experiment, different metals were tested for their reactivity. Beaker was immediately recovered with wire gauze.
The zinc in this video had a coating of oxidation, so the bubbling is very slow. When the reaction was complete, the contents of the beaker were tested with red and blue litmus paper. How to cite this page Choose cite format: Unfortunately the chlorides of magnesium and zinc are not easy to crystallise, while magnesium sulfate is so soluble that it takes longer to evaporate sufficiently.
This decrease can be explained in terms of the increasing effective nuclear charge decease shielding in going from left to right. Metals will give up electrons to become positively charged ions, called cations.
The activity series is a list of the metals in order of ease of reaction, or the ability of the element to give up electrons. The larger the atomic radius, the less significant each electron becomes and therefore, the less of a problem it is for an Alkali metal to lose one. Tweezers were used to drop sodium into a beaker half-filled with water.
Theses steps were repeated with lithium and potassium. The IE increase from bottom to top and left to right in the periodic table. 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.
Similarly, a higher concentration of products tends to be associated with a lower reaction rate. Press enter to begin your search Reactivity of Metals: Nonmetals will accept electrons to become negatively charged ions, called anions.
The calcium was added to the beaker.
Similarly, a higher concentration of products tends to be associated with a lower reaction rate. Therefore in this reaction, a more reactive metal will displace the metal ion in the compound and thus it will be separated. If small crystals form on the glass rod, stop heating, otherwise continue until that point is reached.
Bunsen Burner Lighting, many of the students have difficulty using the flint strikers. Moreover, it will be the hottest when the reaction between magnesium and copper sulphate takes place. Data from Table 2 was collected by obtaining a solution of metal ions and dropping in a piece of metal.
Metal reactions with HCl acid with observations and net ionic equations. Unfortunately the chlorides of magnesium and zinc are not easy to crystallise, while magnesium sulfate is so soluble that it takes longer to evaporate sufficiently. When an unstable compound is broken, not much energy is used up and thus it is expected that all four reactions will be exothermic.
Solid metal was placed in a metal ion solution to determine if a reaction would occur. The atomic radius of an atom can be obtained by measuring the distances between atoms in chemical compounds. The metals from Table 2 were compared to each other in order to create an activity series.
The gas produced by the reaction was collected in a test tube by the downward displacement of water. Teaching notes student sheet available with this resource and get the students to work each question after observing the reaction.
This means the attractive force holding the electron is stronger and it takes more energy to pull the electron off. When the active metals reacted with water, the resulting solutions were basic. The purpose of this lab was to test the reactivity of certain metals, then create an activity series demonstrating the metals’ tendencies to be oxidized.
Solid metal was placed in a metal ion solution to determine if a reaction would occur. 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.
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.

Objective. SWBAT work safely in lab to observe metals and nonmetals becoming ionic compounds. Big Idea. In Part 4: Reaction of Aluminum metal with aqueous Copper (II). AbstractThe rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab.
The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered.
