u know the amazing thing abt this teacher is he teach for us to clearly understand things so we'd know the basic idea and try to solve it on our own and not for us to memorize, u r amazing teacher!!!! 😭😭😭❤️❤️❤️ Thank u so much I finally have hope for chemistry!!!! Watch me promoting ur channel everywhere 😣❤️❤️
Hi Mr Martin, your videos are very useful, I thank you for uploading your videos. My chemistry improved from 32% to 62%. Thank you. I will stay tuned for your videos. Can I request you to do the form 4 chapter 5&6? I really cannot understand this 2 chapter
Thanks a lot Mr Martin.. Your teaching is easier to understand as compared to read the reference book. Save my time as well.. Appreciate it.. Keep producing more videos.. 😄
Sir martin you are literally the best teacher. Your explanation is on point. Love the way you teach. Is there by any chance that i can get a lesson 3 on this chapter ? Lastly, thank you sir 😊 you are really helping us student 👍🏻

Hello teacher, so you mentioned that the soluble salt crystals formed has to be washed. The thing is, if it is washed, why does it not turn back into liquid form ? Non of my reference book has an answer for this :(
We are using a small amount of wateer to rinse the salt crystal and we will keep the rinsing process short and quick.There will be a small part of crystal dissolves in water again but a big part of it will still in solid form
@@HoshikawaHikari i like people who really think deep about information they received and dare to ask question.This will help u to understand rationale behind those concepts,keep it up
I would like to ask if the commonly used acid and alkaline is not able to produce out the salt provided by the question, then what acid or alkaline I should use to produce out the salt provided by the question?
For SPM, u will be tested on preparation of salt using common acid and alkali only. In the real world, there are many more acids and alkalis which are available, subject to which salt you want go prepare, then you choose youe material accordingly. Example : To prepare a special salt like Barium ethanoate, you might need to use a special alkali Barium hydroxide and ethanoic acid.
1:15:00, everything is done perfectly. if i want to use Zn powder instead of ZnO, is it ok to do so? if i do so, the procedure below will be different, especially procedure no.2, only hydrogen gas formed, no H2O at all. so how am i going to continue it in the drawing part?
Everything will be the same even u use ZnO, because the salt produced is a soluble salt, so you will still get it in liquid form. Although there is no water produced but not to forget, there are water content in the acid
@@MrAprolsmatic ok so my chemical eqn will be, 2HNO3+Zn--->Zn(NO3)2+H2, but while i drawing diagram, especially procedure 2, can i still draw like how u draw and label it Zn(NO3)2+H2O+excess Zn powder? and follow watever u done till the end?
thank you so much, help a lot! and I wanna ask about that for the acid reaction, is it we can choose any one from metal/metal oxide/metal hydroxide/metal carbonate without any rules? just simple choose any of them we want to use?
Must choose the metal /oxide/hydroxide/carbonate that is related to ur salt.Example,we want to make zinc chloride by using acid reaction method.So use Zn/ZnO/Zn(OH)2/ZnCO3
Most common way to ask is a flow chart question that ask about salt test such as heating test combine with reaction of Acid. For essay, will test on procedure to prepare a salt
btw, we can identify charge of an atom by looking at periodic table. lets say like sodium, Na+. why Na+, why '+', is because Na can dump 1 electron to be stable; why Aluminium, Al3+, because it has to dump 3 electron to be stable; why Chlorine Cl-, it has to take in 1 electron to be stable. ok la for these substances ok, can identify thru their valence electron n so on. but if i move on to transition element, like silver, as u mention on 5:16, how can i identify whether if silver is Ag+ thru periodic table?
Transtion element has multiple oxidation number, you only learn about those concepts in higher level such as STPM, Alevels, Matriculation. In SPM, we need to memorize those charges as early as F4 Chapter 3
@@zhonghuawansui as what you learnt in F4 Chapter 4, transition elements have 4 special characteristics. One of it was multiple oxidation numbers. The reason of why transition elements have multiple oxidation numbers will be covered in pre-U/college level. If you want to find out more about this, you can Google "multiple oxidation number 4s and 3d"

Hello sir. I have a question regarding the essay questions. Is it necessary for us to write the material and apparatus needed for the experiment or just label those in the diagram we draw?
Sir.. at 55:21 [for neutralisation] you said when acid react with base(=those who have oxide or hydroxide) it will form salt & water. For all metal hydroxide, they are alkali. so isn't it that the titration method is the same as the neutralisation method
@@MrAprolsmatic hi teacher, the success chem book says method to find SPA soluble salt is through neutralisation using titration, does that mean this ans is accepted in SPM? even though u said acid reaction using neutralisation method? Just asking out of curiosity ahaha have a nice day :)
@@nobody0-070 yes, in general we have two types of neutralisation reaction. Acid + soluble alkali is known as titration method, which is meant to prepare SPA salt. Acid + insoluble base, carbonate known as acid reaction which is used to prepare soluble salt without SPA. Hope this clarifies
