S3.1.10 Colour of complex ions (HL)

This video covers the colour of complex ions.

ive never understood this part in textbook or any notes and just memorised the default answer. But now understanding it makes it so much easier to apply without memoring it. Thank you so much King!

[@MSJChem]

Glad I could help.

[@RadhakrishnanPalani]

this is so cool. finally understand why they are colored, beautiful explanation btw

[@ollymagics]

I never understand this,,,but u make me good of this concept today,,,,thanks alot

[@MSJChem]

Glad I could help.

[@climax7260]

Thank you! You are helping me understanding chemistry concepts. God bless you!!

[@Boooommerang]

Wowwwwww! Congratulations! Perfect video, thanks

thank you for clearing up this topic. welll explained

Thank you sir this was too helpful and easy to understand ⭐

Hi, back again binging your vids.
When the orange light is absorbed by hexaaquacopper (II), shouldn't the electrons eventually de-excite and emit photons of orange light as well? How is it that we continuously see the solution as blue and not as a fluctuation between orange / blue? Is it because there is a continuous white light source?

[@MSJChem]

Basically yes. The white light is necessary for the solution to be blue.

amazing thanks

[@iman766]

Thank u sir!

[@chijiokechidinma5456]

Thank u so much sir for dis great lessons u 've taught. Sir pls l have a question what if we were given a complex ion how do u know the colour of the complex ion because l understand that when u knw d complex ion colour like copper is blue n d opposite complimentary colour is orange. But hw do u knw is blue

[@MSJChem]

Students are not required to know the colours of specific complex ions so the question should tell you what colour it is.

Good

Hi Mr Sugiyama, are these updated videos containing new content?

[@MSJChem]

Not necessarily new content - although some might have. I am just updating these videos because they are quite old.

[@kivanickyalew2074]

@@MSJChem so, is this based on the new IB syllabus?

[@MSJChem]

It is based on the current IB syllabus.

[@josephedmonds8252]

Great video! One question though, why is the transmitted light complimentary to the light absorbed?

[@MSJChem]

The colour wheel only gives an approximation of the wavelengths of light transmitted. It’s not entirely accurate but is good enough at this level.

[@josephedmonds8252]

@@MSJChem Thanks mate, makes sense.

[@ewegg1271]

Why are some colours so intense, like the intense red of Fe(SCN)(H2O)5?

[@MSJChem]

The colour depends on the wavelength of light that is transmitted (and absorbed) by the solution of complex ions.

[@anonmela]

Thank you for the video, its amazing but you said that Manganese(Mn) isn't a transition metal but im sure that was a small mistake :)

[@MSJChem]

Didn’t I say that magnesium is not a transition element?

[@anonmela]

@@MSJChem Yeah, You said Manganese was not a transition metal, Im pretty sure it is

[@MSJChem]

At the start of the video I mention magnesium not being a transition metal. It sounds similar.

[@smu_13109]

Sir I want to request can u plz upload a lecture regarding metalurgy of copper along with its refining
Plzz sir

[@MSJChem]

Seeing as this is not a part of the IB syllabus it’s unlikely that I’ll make a video about this - but if I get the time I might get around to it.

[@smu_13109]

@@MSJChem Ok sir no problem

[@t4gguk]

Isn't the valency of copper [Ar] 4s1 3d10? Why is it written as 3d9 here?

[@MSJChem]

It’s the Cu2+ ion

[@t4gguk]

@@MSJChem Oh! Thank you so much for clearing that up
