AQA 2.6 Reactions of Ions in Aqueous Solutions REVISION

[@racheldoran9758]

Timestamps: 2:30 = introduction to metal-aqua ions 4:38 = acidity of aqua ions (2+ vs 3+) 9:42 = further hydrolysis of metal-aqua ions using OH- 14:51 = amphoteric metal hydroxides (i.e. Al(H2O)3(OH)3) 19:12 = reaction of aqua ions with ammonia 23:20 = reactions of aqua ions with carbonates 26:59 = test tube reactions of Cu2+, Fe2+, Fe3+ and Al3+ (Required Practical 11) • 29:07 = reactions with sodium hydroxide • 30:11 = reactions with ammonia • 31:26 = reactions with sodium carbonate 33:35 = complex ion solution colours

AQ ions shouldn't b on the spec/can't memorise all these colours

[@javhus100k3]

its not that bad

[@lol.1296]

@@javhus100k3 be so fr

BUTTER THEM IONS UP BOIIIIII

[@feyioni-williams814]

wow this is just so helpful thank you!

[@hrishidave7519]

why isnt the metal inside the square brackets in the first slide but is on other slides?

[@libbyharris1749]

be chill dude

[@zoegarnett9601]

i suspect it was a mistake, the transition metal ion should be inside the the square brackets

[@BinhNguyen-vl2dx]

does it matter if the OH and the H20 are switched around, and likewise for the NH3 and H20 precipitates at 37:14?

[@fahmidahahmed3607]

no it doesn't

[@miinziiiiiii]

No

[@mlakmohamed1900]

why is there no sodium for the sodium carbonate reaction I'm so confused is it like a spectator ion or something

[@tywinislitandeddard9988]

yes

[@SpiderkingG]

Good luck to everyone. IT BETTER NOT BE LIKE PHYSICS PAPER 2

[@AlleryChemistry]

Hope it went well 👍

[@SpiderkingG]

@AlleryChemistry it was a nice paper. And easy calculation marks I rate it AQA. 👍

[@nasnous8064]

nice intro

[@miinziiiiiii]

36:25 why are the same Fe3+ hydroxides different colours

[@Elias.04]

They both should be brown :) The bottom row also produces bubbles of CO2
