In addition, your name will be written in the credits section of this post. The A2 revision Topical notes are not complete. They are only till chapter 26…please upload the rest. They are awesome notes. Please do upload some As chemistry P3 notes I always stuck in solving questions of p3. This is a very nice website, a very established one indeed. Please do visit my website, if you have the time. You may find something which may be very useful to you. The notes are precised and to the point.

Hi Aadarsh, I have checked and the permissions are fine. Hey guy I am an As student can someone help me and will solve the problems together with me on whatsapp this is my number Hey Bro A Few days ago this website was working well. Thank you for the notes. However, for lattice energy in A2 Revision topical notes 2, the images are not coming out at all and there is failure of printing.

Please fix. I have contacted the creator of these notes and I will update you as soon as Chapter 20 is fixed. You should keep the syllabus on hand. They were not made for the syllabus but most of the things are there.It is written by students around the world who have aced their exams and wish to collaborate, wanting others globally to learn and excel as well.

Biology, chemistry, maths, information communication technology and physics. Even now during my A levels, Znotes has not ceased to aid my tests and attentiveness in class.

I put more thought onto it and turned from being the one requesting to the one creating. I took initiative and contacted the owner through slack, and was soon sent the template around August.

I studied the EM syllabus, but had to make notes for The content was so vast and explanatory, not straightforward like so in my textbook. I had to make sure the many pages I read were shortened to succinct note form, and that they correlated with the syllabus content. Formatting was not that hard, but super time consuming. Appropriate punctuation, bullet levels, images, headers— you name it.

Soon I realised it is a stepping stone towards making a difference and helping people in this world, which has always been my ultimate goal whilst carrying out all my actions. It looks very professional, covers the entire syllabus, and in the end I just really hope all my hard work and effort pays off. Before I conclude, I highly encourage you all to check the notes out, perhaps by skimming through just to view the amount of effort it took us and let me know your thoughts!

Collection Of Gases: Upward Delivery: Upward delivery is used to collect gases that are less dense than air. Hydrogen and Ammonia. Downward Delivery: Downward delivery is used …. Matter: Matter is any substance that has mass and occupies space.

When dissolved in water, they can conduct electricity. Acid reacts with Metals to produce …. Bases: Bases are metal oxides and metal Hydroxides. Salts: Salts are Ionic Compounds. A Salt contains a positive metal ion and a negative non — metal ion. Properties Of Ammonia: Colourless gas, with strong choking smell.

It is less dense than air and reacts with hydrogen chloride gas to form a white smoke.

Ammonia is soluble in alkaline — reacts with acids to form …. Sulphuric Acid: It is a colourless oily yellow liquid, with density slightly higher than water. It is soluble in water and emits heat when dissolved in water — exothermic in nature.

Sulphur is burned in …. Writing Ionic Equations: An ionic equation is a simplified chemical equation that shows the reactions of ionic compounds in water. Ionic compounds are those compounds, which are soluble in water. Inorder to write an ionic equation: Write the balanced chemical equation of the reaction.

Practical skills are assessed in a timetabled practical examination. The emphasis throughout is on the understanding of concepts and the application of chemistry ideas in novel contexts as well as on the acquisition of knowledge. The course encourages creative thinking and problem-solving skills which are transferable to any future career path. Cambridge International AS and A Level Chemistry is ideal for learners who want to study chemistry or a wide variety of related subjects at university or to follow a career in science.

I think it is better to limit the volume of syringe to less than cm3. Also, the volume of a commonly used small test tube is around 16 cm3 and that of a boiling tube is about 25 cm3.

We always have to keep the volume of the apparatus we are using while choosing the volume of the solution for the planning. Saying that we are going to place 50cm3 of aqueous HCl in a test tube is of course not going to please the examiners. I think I ended up doing the same in one of the papers where we had to prepare different concentrations of a given solution. I chose volume of water to be added to a beaker to be cm3. However, the ER stated that the volume should be less than cm3, that so being since the volume of a commonly used glass beaker is around cm3.

Someone carrying out my expm would have a fully filled beaker. However, we can use greater volume if we state that the volume of the beaker is cm3 or cm3 or so on. So, stating the volume of the apparatus is very very important. The question of percentage errors are usually asked in P5. The percentage error becomes very unacceptable if we are measuring SMALL volumes of solution or small masses.

While heating crystals strongly, do not use a simple test tube or any apparatus with sharp edges as they are liable to crack at the sharp edges. For very strong heating to a constant mass, a crucible placed on a pipe clay triangle is appropriate. So, allow the crucible to cool for a few minutes by placing it on a heat mat. How to prepare crystals which is also linked with solubility Many methods are mentioned in MS but I found this to be the simplest: CIE usually demands us to prepare crystal after preparing a saturated solution of the crystal.

So, we have to prepare a saturated solution first: 1. Take a fixed volume of water in a beaker of appropriate volume 2. Add the crystal to the water and stir continuously. You have to allow some time for the crystal to dissolve as it is an equilibrium process 3. After 5 min of stirringif no solid crystals appear, add further mass of crystal 4. And repeat the process until solid appears in the beaker 5.

Filter the solution using a filter paper and funnel so that the saturated solution is collected in a beaker whose mass has been measured previously beneath the funnel Now we have a saturated solution in a beaker. How to get the crystals: 1. We have to place the beaker in a warm water bath. We could use a burner as well but there is a risk of overheating the solution which could decompose the crystal. If the heat is appropriate, the water of the solution should evaporate and we should have dry crystals ready.

How to measure solubility: 6. Subtract the mass of beaker from the mass in 6 to get the mass of saturated solution 8. And evaporate as shown above to get the mass of crystals. Subtract mass of beaker from mass in 8 to get the mass of crystals Subtract the mass of crystals from the mass of saturated solution to get the mass of water in the solution I have assumed that all the masses are in grams.
