Dear Professor Davies, I cannot agree more with the method of going back to binary before looking at ternary when identifying the primary phase regions and univariant reactions.
Sure, A2B and AB2 melt incongruently as they yield a solid and liquid with different compositions when they melt. AB melts congruently and forms eutectics with A2B and AB2 (pure A and our B also melt congruently). Hope this makes sense.
Identify the solid phases and liquid involved; if the liquid composition is in between the solids it is a eutectic; if the liquid is outside both of the solid phases, it is a peritectic. Hope this makes sense.
underrated video. Still have a lot to understand but this is one of the better videos I found on the subject
Finally find this video series, that's exactly what I need!
I hope they are helpful for you.
Thank you for explaining this very well! It was confusing at first, but helped at lot. Thank you sir.
Glad it helped!
Thank you for your videos, they really help a lot and are of very high educative quality.
Thank you! Glad they were useful; I hope to post more in the near future.

Thank you for explaining this, very good video!
You're very welcome!
teacher which app did you use to draw these 🫶🫶 ty for your explaination
These are all powerpoints
14:37 , sir can you tell me which compounds are incongruent mealting compound

How can you tell when a binary reaction is either eutectic or peritectic?

Great thanks Sir
You're welcome, glad you enjoyed it
Thank u!!! We have a test on this and was only giving one example in class. So confused
I hope the videos help, good luck on your test.
@@peterdavies6179 thank you! I already understand so much more, thanks to your video
