Qualitative analysis of cations part 1

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.

Nice video but it is good to tie hairs in lab aise khol k rakhna is dangerous

[@arinarahman3758]

Why?

[@arinarahman3758]

What will happen?

[@prachipanchal3347]

@@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?

[@arwasafwat7703]

why if we add more sodium hydroxide to the zinc solution it re-dissolves?

[@vyshunikki8875]

The ppt is soluble in excess of NaOH due to formation of sodium zincate

This helped a lot thankyou!!

Nice

Wow 4G chemistry.

[@user-dl7jy4yv8r]

Why do you use only NaOH to test for the cations

How to prepare Sodium hydroxide solution?

[@Irfan-uz3tg]

sodium oxide + water? idk just my guess.

[@druthisripada2011]

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.

[@tariqmehmood-yg7hf]

It is very informating videos

[@agharapriyank9216]

can you tell me that the solution of all cation make in which solvent??

[@hambilierickson8117]

Test for confirming the presence of copper ions Cu2+

[@sandamalikirtisinghe6195]

its pretty fast. and u should be a bit more informative
