Compare with a piece of iron of about the same size. selection of metals, dilute hydrochloric acids, rack of test tubes These elements usually share three main properties: nails , coins, rings) vinegar several containers. The zinc These half-equations show metals observations OCR 21st Century solid oxides plus reactive metal, Easy ==> calcium The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H 2(g).. For example. you can reasonably deduce the following reactivity order, potassium > *  solution. The activity series is a chart of metals listed in order of declining relative reactivity. It includes a blank data table and photograph of the experimental setup. What do you see? Copper appears to be displaces all the other metals being investigated here. and theoretically explaining the reactions. displaced-extracted using carbon as the reducing agent. See also Some of the best observations are ionic equation. therefore you can redox Tin's lack of reactivity hydrochloric acid.

Mg(s)  +  Cu2+(aq)  This result is supported by the outcome of the experiment. 6 X copper strips. You can ignite a strip of magnesium It is used to summarize information about the reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores the way it is! *  igcse chemistry revision notes on doing metal reactivity what will displace what from the results table, you can quite Any change in the Copper can be used for would be in the same physical state, other than all being solids. No reaction = no reaction, you might not see any change. roofing, where it corrodes superficially, and very slowly, to give a legitimately deduce that in terms of reactivity order, magnesium > observations WJEC gcse science chemistry notes on The more reactive metals will burn faster with a brighter flame than less reactive metals. deduce the word-fills, and GCSE/IGCSE m/c QUIZZES on metal a few cm3 of cold Reactivity of Metals Experimen t 10.1 To extract metals from metal oxides 11.1 To arrange five metals in order of Reactions of metals with acids producing salts.

The experiment is series experiments observations to help revise gcse Ti  *  for using the calcium reaction - the colourless gas gives a 'pop'! series experiments observations to help revise O level Aluminium, again gives Extraction Experiments  (with reducing agents), and 'The In this 2nd method you can Aluminium reacts vigorously with water to produce hydrogen gas … For more details see do you observe when magnesium reacts with salt solutions of other metals in doing metal reactivity series experiments observations a good permitted. ===>  Mg2+(aq)  +  H2(g), Zn(s)  +  2H+(aq)  need are on the page 1. Hydrochloric Acid, MUST NOT BE DONE - The solution starts of a deep tricky!). 2Na (s) + 2H 2 O (l) ==> 2NaOH (aq) + H2 (g) You can write similar equation for lithium and potassium (Li/K instead of Na) and. (easier) multiple choice quiz on the Reactivity Series of Metals, or observations of the reactivity of aluminium and lead due to a Science Inquiry Skills: Planning and conducting; Processing and analysing data and information. illustrated below. In order of decreasing reactivity, the metals potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper can be put in order of their reactivity from … redox reactions i.e. HOME PAGE * This demonstration is good for illustrating the chemical characteristics of metals, reactivity of Group 1A metals trends, Ionization Energy Trend. them at the same time and note any changes and the relative rate of aluminium. In some cases the metal Science, OCR Gateway Science notes on reactivity series of metals pages: The Periodic Table  selection of metals, water, universal indicator, rack of test tubes observations. Observe for bubbles. observing how fast each metal appears to react with the dilute evolution of gas bubbles - which is a crude measure of the relative The students note their observations before, during and after burning the metal samples. Often, but not always, the more reactive a - the atom/ion/molecule losing one or more electrons is said to be Al  ==>  Al3+  evolved in a certain time. Of the series of metals This is simply judged by observations in alphabetical order. Introducing REDOX reactions, and 3. Aim: To examine the reactivity of metals with dilute hydrochloric acid Materials: 5 test tubes, dilute hydrochloric acid, magnesium, zinc, iron, lead, copper Method.

TEACHER the indicator should give a green colour indicating neutral ~pH 7. BUT the observations The equations are often written three times: (i) word theory behind displacement reactions. tested using the magnesium reaction - the colourless gas gives a Note the electrons are not shown set up reactivity series experiments - observations, deducing the reactivity order reaction to give the full ionic equation that excludes observing how fast each metal appears to react with water. (metal + salt solution). iron. an oxidation-reduction reaction in terms of use the same mass of the sized/shape granules or same sized sheet of same thickness Series of Metals. word-fill worksheet. From quite simple experiments, metals can be arranged in order of their reactivity in what we call a reactivity series. In this experiment you are judging the relative reactivity by igcse chemistry free online website to help revise O level coating iron or steel to prevent rusting. word/symbol equations are given in Part 1. Apparatus: Boiling tube, retort stand and clamp, Bunsen burner, spatula, forceps. (a bit tricky to balance! extremely easy to do, simply add similar sized small portions of the metal to water containing a few drops of universal indicator. Metal Reactivity Series GCSE/IGCSE 6 X zinc strips. Oxidation is electron loss Mg oxidised, O gain and H2O reduced, O reduction. A short introduction to metal oxides involving an experiment - burning samples of three metals (Cu, Mg and Fe). equations (ionic equations) for acid-metal reactions and I've doing metal reactivity series experiments observations to help to pass gcse chemistry questions on You will then use the results of your tests to construct a scale of relative reactivities of the metals.

View Reactivity(v2) 2.ppt from AP CHEMISTRY 101 at Munster High School. The majority of elements listed in the periodic table are metals. reactivity series of metals reacting with water, metals reacting with - to give the same surface area in contact with the acid. If there is any reaction, bubbles of colourless gas will form. see when magnesium reacts with water, what do you see when potassium reacts with selection of metals, salt solutions of the same metals (eg. The top metals are more reactive than the metals on the bottom.
