AQA A-Level Chemistry - The Alkaline Earth Metals (Gp. 2)

This video runs through the Gp. 2 topic of the AQA spec. Note that it does not cover trends in physical properties.

Awesome vid! I'd just like to point out something to any student reading this.
By using HCl or NHO3 (Nitric Acid) this removes ions, specifically carbonate ions. This is very important since *BaCO3* (Barium Carbonate) is *also a white ppt*, so its indistinguishable from BaSo4 (Barium Sulfate). So by acidifying it first it removes the carbonate ions so you know the white ppt formed is 100% BaSo4.

You just saved my A-levels. I can't thank you enough, Mr Rintoul. I've been getting E's all year, and it's a miracle that I've found your wonderful channel! I've never understood chemistry well enough from my teachers, or even tutors I got, but with your lessons, it's like magic! Whilst it's a little late with my AS (I wish I found you sooner), I'll definitely be using your videos for my A2 year and push to an A*. Again, thank you so much for everything.

I was getting grade Cs and Ds in Chemistry before I found your videos, now I'm getting As!! Thank you so much for taking the time to make them, they are helpful beyond belief! If I pass this A level it will be because of you!

Thank you, I like how you summed it up in such a short amount of time with everything we needed to know. I learnt more in those 15 minutes, than I did in like 3 hours of class and 2 hours of reading :) x

You said they will lead us into alleyways. My mom always told me not to follow random strangers into alleyways so I'm afraid I can't do that.

Just wanted to say thanks for the effort you have made in making these videos. They have been incredibly useful!

thanks you so much for all the videos, they make life lot easier only if teachers in college could make it so simple. thanks for all the effort in putting these together so close up to the exam, I'm sure every body will appreciate them.
