Copper… and its many different colours
In this post, I am going to talk about Copper. Copper is a transition metal and one of the properties of transition metals is that it forms compounds of different colours. [You need to know this if you're doing O Level Chemistry!] Copper is especially popular among...
read more3 colours that you need to know…
Many students are familiar with the chapter on Qualitative analysis. Most will be able to rattle of the top of their heads very quickly, the colour of precipitates. For instance, copper(II) hydroxide is a blue precipitate, iron(II) hydroxide is a dirty green...
read more3 things you need to know about Acids
The chapter on Acids Bases and Salts doesn't have to be confusing. Over the June Holidays, a couple of students have emailed me with their questions on acids. Rather than answer them individually, I thought of saving a little time and putting it all here in a blog...
read moreThe Solubility Table and what it's used for
The solubility table shows you a list of salts that are soluble and insoluble. In general, I tell students to start by memorising the 5 insoluble Chlorides and Sulfates. Once you can recite that list off the top of your head, then add in most carbonates! (It's...
