AQ ions shouldn't b on the spec/can't memorise all these colours
its not that bad
@@javhus100k3 be so fr
BUTTER THEM IONS UP BOIIIIII
why isnt the metal inside the square brackets in the first slide but is on other slides?
be chill dude
i suspect it was a mistake, the transition metal ion should be inside the the square brackets
wow this is just so helpful thank you!
does it matter if the OH and the H20 are switched around, and likewise for the NH3 and H20 precipitates at 37:14?
no it doesn't
No
Good luck to everyone. IT BETTER NOT BE LIKE PHYSICS PAPER 2
Hope it went well 👍
@AlleryChemistry it was a nice paper. And easy calculation marks I rate it AQA. 👍
why is there no sodium for the sodium carbonate reaction I'm so confused is it like a spectator ion or something
yes
nice intro
36:25 why are the same Fe3+ hydroxides different colours
They both should be brown :) The bottom row also produces bubbles of CO2
