The metals from part a2 of the experiment should be removed from the reactions with forceps, rinsed with water if they have been exposed to acid, blotted to remove excess water, and then discarded in the container for used metals. Lesson 6: reactivity trends (lab work) now let's consider something that is more directly observable let's look at the chemical reactivity of some of the elements and relate that reactivity to some of the properties we have just talked about. Background, cont • you can measure relative reactivity of two metals by placing a sample of one metal in a solution of the ions of the other metal • if the solid metal sample is more reactive, electrons will move from the metal into the solution and the solid sample with become ions and dissolve • meanwhile, the less reactive ion sample will take the electrons and form a solid. A mixture of resources i use for this unit some i have made and some have been reworked all credits are given within the actual documents i cannot take any credit for this work and other resources that are reworked originals.
Upon completion, the order of reactivity of these metals will be determined reactivity is related to two factors 1 st , the fewer electrons in the valence shell, the more reactive an element is. Simultaneously, add a small amount of each of the 2 metals to their proper test tubes record observations and rank the metals in terms of their reactivity with water on a scale of 1 to 2 (1=most reactive, 2=least reactive. Test the reactivity in hot water by placing the entire test tube from step 1 in the hot water bath for 2-3 minutes record your observations test the reactivity in acid by pouring out the hot water from the test tube, then using a dropper put enough acid to just cover your metal into the test tube. The chemical reactivity of a metal determines how the metal is used for example, gold, which is commonly used in jewelry, is highly resistant to experiment 15 reactivity of metals 97 05_lm_se/te_lab15 5/16/04 1:29 pm page 97 safety first in this lab, observe all precautions, especially the ones listed below if you see a safety icon.
The reaction of some metals with standard 1 m hydrogen ion is dangerously exothermic, so we will begin our tests by studying the reactivity of metals with pure cold water, in which the concentration. Reaction of alkali metals with water purpose: to compare the reactivity and properties of li, na, and k name an alkali metal that is more reactive than k, na, and li name an alkali metal that is less reactive 6 all metals in this lab, reacted according to the equation: metal + water → metal hydroxide + hydrogen. The reactivity series allows us to predict how metals will react a more reactive metal will displace a less reactive metal from a compound rusting is an oxidation reaction.
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. Reactions occur and which don't, you will be able to figure out their relative reactivity (activity series) for example, you have 3 metals a, b, and c and their salt solutions ano 3 , bno 3 , and cno 3. Should list the five metals used in this part of the experiment: copper, iron, magnesium, tin, and zinc once the lab was completed, i realized that there are different levels of reactivity between all metals. Results: questions: #1-8, page 143: 1 which metal reacted with the most solutions although both magnesium and zinc showed reactions with copper nitrate and silver nitrate, magnesium’s reaction with copper nitrate was more apparent than zinc’s. 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.
Pre-lab 1 a single-replacement chemical reaction is one in on its ability to gain or lose electrons 3 a more active metal tends to lose electrons more readily than a less active metal 4 see hypothesis teaching the lab laboratory manual: teacher edition author: glencoe/mcgraw-hill subject. Five different metals are placed in hydrochloric acid in order to rank their reactivity. The reactivity of metals are affected by the number of shells that the metal has and the number of electrons in its outer shell 3 always wear safety goggles, gloves and a lab coat.
Caesium, the fifth alkali metal, is the most reactive of all the metals in the modern iupac nomenclature, the alkali metals comprise the group 1 elements, excluding hydrogen (h), which is nominally a group 1 element but not normally considered to be an alkali metal as it rarely exhibits behaviour comparable to that of the alkali metals all. Lab: reactivity with metals purpose: the purpose of this lab is to determine the reactivity of various metals with water as well as potentially acid and be able to place them in order of reactivity hypothesis: if we test the reactivity of alkali metals, alkaline earth metals and period 3 metals, then the least reactive would be aluminium, then. The purpose of the lab was to find which metal is the most reactive and which metal is the least reactive it was known before the experiment that the metals used in the experiment are placed in the activity series from most active to least active as follows: magnesium, aluminum, zinc, and. The alkali metals make up group 1 of the periodic table this family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium (li, na, k, rb, cs, and fr, respectively.
The reactivity of the metals is exactly opposite the reactivity of the corresponding cation while solid magnesium was the most reactive metal, its ion, mg 2+ , was the least. Lab: some metals are more reactive than others plan: rank the five kinds of metals according to their reactivity, by measuring and comparing the speeds for the metals to be reacted in hydrochloric acid title and date some metals are more reactive than others aim and research question. This introduction includes a poe reactivity of metals activity, cornell notes reading activity, and a summative assessment activity the order of instruction is as follows: complete the poe reactivity of metals activity. Lab 1 reactivity of metals essay lab: reactivity with metals purpose: the purpose of this lab is to determine density of metals lab 1 purpose the purpose of this lab was answered in 4 questions, and their answers are here shown the density of the metals we used were 5g/cm3.
