GCSE Chemistry Revision "The Reactivity Series"

In this video, we look at how metals react with water and with dilute acids and how we can use this information to order the elements by reactivity. We then explore why some metals are more reactive than other in terms of their ability to form a positive ion.

qutesion for some one who has done their GCSE's , did you need reactivity series . did u need to memorise which reacts with acid and water and which don't ?? do u need to know this, if no would it have helped to know it off by heart . ?

[@a24udy]

besttttt science teacher everrrr

[@unknownguy1699]

I'm struggling to understand this question in my textbook. "A student placed a strip of magnesium into a solution of zinc chloride. What, if anything, would of observed, and why?" Now in the answer part it says that a black solid would form and that magnesium would displace the chlorine from the zinc. I just don't get why a black solid would form when in the videos online it shows a yellow/orange solid formed.

[@Corsaka]

pretty sure zinc is black, and since it's been displaced by the magnesium, it's now present

[@duncanmurray7276]

Hi Sir, I just wanted to ask you about effective revision techniques for science because I am in the process of learning your revision cards and have watched the videos when the revision cards haven't made sense and it is a reoccurring theme that I continue to get stuck when I actually try to transfer my knowledge onto the actually exam questions. I usually get around a B and to push my grade up I need a significant boost and a way of getting around exam questions, because it seems I have a pretty good level of understanding with the content, however i get to an exam paper and really struggle transferring my knowledge. Just to note I am taking my exams this summer and would appreciate any help. Thank you

[@Freesciencelessons]

Ok this is what I think you need to do. You need to leave the revision cards for a while and watch the videos. The revision cards are great for facts but they won't help understanding as much as the videos and it sounds like that's where you're struggling. Watch the videos first, really get your head around a topic and then learn the cards.

[@duncanmurray7276]

Thank you so much, and would you advise making notes whilst watching the videos ?

[@Freesciencelessons]

Yes lots of students do that.

[@karlasback4175]

hi these videos are really useful and I was wandering if they were just a supplement or could I get all my notes from your videos

[@Freesciencelessons]

It's so slow you would never see it. It does react fairly fast with steam.

[@themilkemissary7898]

@@Freesciencelessons is that because of surface area or because of the thermal energy?

[@WishalSriRanganMU]

Great video sir. May i ask if there difference between GCSE and IGCSE topic wise. In my school im taking 7 igcse subjects and so its called ice. Any idea on what ice is?

[@Freesciencelessons]

Yes, ICE is simply a name given to a certain combination of IGCSEs. It's designed so that students take a range of different subjects rather than a narrow selection. There are differences between GCSE (UK) and IGCSE. The IGCSE has more topics and more depth. However, there is a load of overlap so you should find a lot of my videos very useful.

[@stitchellerowe4169]

these are some useful videos👍 make me feel as if i'm in a class

[@chewypiano7194]

Must we memorise how each metal reacts (vigorously/slowly)?

[@MonkOrMan]

That's what I want to know

[@veronicaturco8217]

@@MonkOrMan I think so on the specification it says: Students should be able to: • recall and describe the reactions, if any, of potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper with water or dilute acids and where appropriate, to place these metals in order of reactivity • explain how the reactivity of metals with water or dilute acids is related to the tendency of the metal to form its positive ion • deduce an order of reactivity of metals based on experimental results.

Hello Sir! What does this mean? Mixing of reagents to explore chemical changes and/or products.

[@fbdjwjflac]

Hi sir, the CGP 9-1 revision guide says that we have to learn the reactivity series, but your video says that we don't. Thank you for the clarification.

[@Freesciencelessons]

On page 40 (bottom) of the AQA Chemistry spec, it tells you what you need to know. You should be able to recall how eight metals react with water or dilute acids and place them in order of reactivity. You don't need to learn the entire reactivity series. They might also give you experimental data on how other metals react and ask you to construct a reactivity series.

Freesciencelessons 2018 exams

[@dilrubadaisy4653]

Freesciencelessons also will your revision cards for new spec help can I use them for 2018 exams

[@Freesciencelessons]

Ah right. Well the C1, C2 and C3 labels really apply to the old spec (finishing in 2017). For the 2018 exams, there will be two papers for each subject (paper 1 and paper 2) but they don't relate to the numbers in the 2017 exams. For past papers, personally at this stage I would not be looking for those. AQA have only released a specimen paper and there are no past papers as it's a new exam. I'll be releasing revision workbooks later in 2017 which will help you with lots of questions.

Hello, do we have to learn the sequence of reactivity servers for our exam??

[@hecticentertainment]

Hello Shaun, what does the aqa gcse chemistry spec mean when it says we need to "recall and describe the reactions, if any, of....[the metals]....with water or dilute acids? What do we need to know about these reactions?

[@Freesciencelessons]

Firstly, you need to know the products of the reaction (ie with water and also with dilute acids). Then you need to know how quickly the metals react with these.

[@hecticentertainment]

@@Freesciencelessons Thanks for your reply. When you say 'How quickly', is that just meaning, "Rapidly, quite rapidly, no reaction", as stated at 3:00 or do we need to know more than just this (the part where it says "describe the reactions" in the spec is making me think how much I actually need to know about them...?

[@hshaikh2360]

thank u very much for sharing this info in really easier way u have remove my confusion thanks a lot again.

[@mishagarwal]

Sir,do magnesium and zinc seriosly dont react at the room temperature...as u have told in the vedio bt when we did the experiment in school it reacted...so what is the right answer sir...

At room temperature, neither magnesium nor zinc will react to any real degree (you might see the odd bubble but not much more).
