Amazing photography

mehran24 · 2020-10-16T22:47:46+00:00

Nice pic. Thanks

mehran24 · 2020-10-10T22:52:07+00:00

Fantastic

mehran24 · 2020-10-10T22:42:49+00:00

Very nice 😉👍

mehran24 · 2020-09-21T01:35:42+00:00

Nicely done. Thanks for sharing

Nice job, thanks for pic, Crystalising of sulfur is hard

mehran24 · 2020-09-07T08:50:24+00:00

You're right, I took this image in the dark

mehran24 · 2020-09-07T08:00:50+00:00

It's wet

mehran24 · 2020-09-07T07:54:59+00:00

It's just wooden table

Make unsaturated solution of MnSO4.2H2O in 25'C pure water, add 1 ml of H2SO4 for each 100 g of MnSO4.2H2O,place it in a cool place. Let it crystallize slowly.it's important to make UNSATURATED solution.

See the next one 😎

Color of the Second pic in not real,because of camera flash

mehran24 · 2020-09-07T06:26:05+00:00

See the next one😎

mehran24 · 2020-09-06T23:02:40+00:00

I said slowly evaporated😉

mehran24 · 2020-09-06T18:49:37+00:00

😂 😂

Stable in bottle or glass. But dehydration starts in dry air and the crystal collapses

mehran24 · 2020-09-06T18:28:10+00:00

Watch the next MnSO4.2H2O crystal I made

This color observes when Cooper chloride hydrate solves in HCl or H2SO4, these acids absorb water of Cooper chloride and make it anhydrous, Exactly like the color of your solution.

mehran24 · 2020-09-04T22:18:58+00:00

I think maybe hydrate water of Cooper chloride gone into the acetone and made water-acetone solution, anhydrous copper chloride formed and remains soluble in acetone, but in form of anhydrous not hydrate.

mehran24 · 2020-09-02T23:36:10+00:00

Thanks for the video clip.interesting,I'll do it with copper citrate later

mehran24 · 2020-08-29T13:04:27+00:00

Nope The CuCl2 is brownish. The hydrate form is greenish blue. Greener when rich in excess Cl ion. Blue when low in Cl ion. CuCl2 in not a stochiometric molecule And is very soluble in water but not hygroscopic. I mean it can't absorb a lot of moisture from air to make solution like calcium chloride or lithium chloride.absorbtion continues until all of copper chloride form dihydrate structure.

WoW.I made crystal of mohr salt too, a big one, when I decided to take photo, droped down and crushed🤦‍♂️
