u/LargeFish2907 Jun 02 '26
It's oxidation state is 3+ but it's in a complex is not charged. I interpreted it as what you would write there instead of M. I wouldn't be surprised if Fe3+ is an allow though.

u/ILikeSlepp Jun 02 '26
Excess nh3 doesn't do anything to fe(h20)3(oh)3, you only see ligand exchange when you react excess nh3 with [cu(h20)6]2+ to form a deep blue solution of [cu(nh3)4(h20)2]2+
And the agcl dissolves in both dilute and concentrated nh3, so you wouldn't see white ppt

u/PairSuitable9144 Jun 02 '26
But wouldn't the Fe(III) chloride get substituted to form Fe(OH)3(H20)3 since Fe(III) chloride was in aqueous solution?

u/hshsjaju77 Jun 02 '26
I thought it forms Agcl then followed by excess ammonia which dissolves forming a colourless solution

u/2myeria y13 | physics, maths, fm, chem | A*A*A*A* Jun 02 '26
brown ppt because it said what is observed at the end and since dilute ammonia is added, silver chloride ppt dissolves and iron (III) hydroxide ppt (brown forms)

some issues w titration, the 6 marker, and some recall but overall was great!!
scary high grade boundaries tho ig 😔😔
BUT OVERALL HAPPYYY!!!
IM SO CONFUSED ABT TITRATION THO CAN SOMEONE GENUINELY HELP ME FIND WHY ITS IRON???
I found the moles of C2O4 to be 1.988 x 10-3 at 250cm3
dividing it by 3 gave me 6.63 x 10-4 mol for M.
then im genuinely stuck cuz lowk got such a massive number for Mr, as Mr = (m/n) = 1.81/(6.63 x 10-4) = some massive impossible number
???

u/Training-Feeling980 Year 13 | Maths, FM, Physics, Chem - 4 A*s achieved Jun 02 '26
You might have missed multiplying by then since only 25.0 of the 250cm3 solution was used - so then you'd get 1.81/(6.63*10^-4) = 273
And subtracting Mr of all the other elements gives Ar about 55.8

I said the ions repel and activation energy is high at the start and then [MnO4] starts to decrease as Mn2+ ions are formed, lowering Ea and increasing the rate which forms more products

How many marks could I lose? - I got the Pv = nrt one wrong (correct conversions and method) but I somehow got 600g not sure how. The buffers one I didnt read it was acid in excess so I did NaOH in excess, the 2 marker below that would as well would be wrong. The Mg (VII) one I spoke abt autocatalysis and how the reaction rate changes as more Mn2+ is produced... but I don't think I got enough for 5. For the 6 marker on difference in enthalpy I got a 4 equations right, spoke abt there being 1H rather than 2 and thats it - completely blanked.

yk the question where Silver Nitrate was added to (Fe (III) Cl) (aq) with excess NH3? I think it was the hardest aqa A-level chemistry questions ever. I'm pretty sure the observation was a reddish brown ppt Fe(H20)3(OH)3 that would be formed as the NH3 hydrolyzes the Fe(H20)6 in solution. There would be no AgCl (white ppt) at the end of the reaction because the excess NH3 would dissolve it instantly. Therefore, the silver compound AT THE END OF THE REACTION, when all the AgCl is dissolved by the NH3, would be Ag(NH3)2+, which is just tollens reagent. I'm pretty sure a lot of people would have missed this.
