Enthalpy of Solution 1

[@persianmelon1788]

This is so good, it's like listening to Jon Snow teach you Chemistry :')

[@geeekA91]

You sir, are A LIFE SAVER i wish my teachers were like this watched all of your vids....#bringonf325!!!! ❤️

[@MaChemGuy]

You dee x, have made my day! Good luck tomorrow :)

[@geeekA91]

No problem, exam went OK i think...have you seen the paper yet? Can you predict the grade boundaries please!

[@MaChemGuy]

Won't see it till tomorrow. General reaction seems to be it wasn't very nice?

[@geeekA91]

Okie doke, and yes people did say it was hard...i think it was a fair paper...it was do-able dont know how i feel about it! Hope boundaries are low🙏👍

Thank you so so much for these videos Sir, they're brilliant - so clear and calm :) I'm actually feeling ready for f325 tomorrow thanks to you! Best teacher ever!!

[@unknownhacker4160]

Such a very good explanation. Been confused for so long up until now🙏🙏

[@TheHammond101]

such a good explanation

[@devon3766]

Thanks so much!

FOR LATTICE ENERGY , it is not always correct to say that ionic lattice is formed from gaseous ions. sometimes giant covalent solid is also formed by combination of ions.

How would you know if the enthalpy of solution is negative or positive

[@MaChemGuy]

There's no fixed pattern to them I'm afraid. You just have to interpret the info given in the question. Delta H lat and hyd will always be more exothermic when ions are smaller and have greater charges, but sometimes the lattice enthalpy will be more significant e.g. in group 1 fluorides and other times its the hydration enthalpy e.g. in group 1 chlorides. Not nice :(

Ross Noble does chemistry videos now :O

But he's a Geordie!
