Good video. Interestingly, this is not permissible in the UK now - cobalt(II) salts are classified as being potentially hazardous such that they are not allowed to be handled by undergraduate students in schools or colleges. Such happy memories of using self-indicating CaSO4 chips with CoCl2 as a drying agent for organic solvents. The blue colour leaches out in many solvents - e.g., acetone. :D

We recently used this in our laboratory for our Engineering Chemistry class. Btw, I'm from Philippines
Surely the hazard is real? potentially hazardous is a tautology.
nice music in the background
thank, this is really helping me with my revision.
Crystal Field Theory,Water is a weak field ligand and there are Oh-splitting,d2sp3.
nice rhank you am watching in 2024 reply
Ye kis cotton ki fasal me kya kaam karta he
Please quick response
Is this a physical change or chemical change
dk if I'm still on time but, I'm pretty sure it's chemical (I'm studying this for chemics lol)

Nice Cobalt , but tell me from where you have CO atomic number - 27 ? from china ! or USA ???
Nice vid. Next time, I'd suggest wearing gloves with carcinogenic compounds.
Cobalt chlorite per bnao vedio sir
Music 1:11?

Theyre as bad as me
