Qualitative analysis of cations part 1
Vložit
- čas přidán 10. 12. 2017
- Adding drops of sodium hydroxide solution can help identify cations present in a solution. Some cations will not form a precipitate so they will be identified by the flame test while others can form a white or a colored precipitate.

Well done 👍 ma that's a good job.
When Ca2+ is added to NaOH slaked lime is formed but it is not a precipitate it is a suspension which is commonly called milk of lime.
helped a lot
beautiful watch btw
Helped me study for my AS practical, thank you so much
Thanks for the tips!
Nice video but it is good to tie hairs in lab aise khol k rakhna is dangerous
Why?
What will happen?
@@arinarahman3758 lab coat is weared to avoid accident. Hairs should be tied to avoid any accident, mishap due to chemicals in lab
Mem will you please make video on wet tests of positive radicals & it' s group separation?
why if we add more sodium hydroxide to the zinc solution it re-dissolves?
The ppt is soluble in excess of NaOH due to formation of sodium zincate
This helped a lot thankyou!!
Could you assist me your phone number? Because I have a robgs with you
Which two cations and unions present in given experiment?
she is from dubai guyzz
Nice
Wow 4G chemistry.
Why do you use only NaOH to test for the cations
Thanks 🌷🌷🌷🌷🌷
Hello Doctor, is the chemical composition of silver chloride dissolved in ammonia decomposed by ultraviolet light?
nyc......
Thnx
Thanku mam
It was helpful
Your accent is like Arabic
How to prepare Sodium hydroxide solution?
sodium oxide + water? idk just my guess.
To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. For a 0.1 N solution (used for wine analysis) 4.00 g of NaOH per liter is needed.
It is very informating videos
can you tell me that the solution of all cation make in which solvent??
Test for confirming the presence of copper ions Cu2+
its pretty fast. and u should be a bit more informative
Cat ions
👍
