i am soo thankful this really made it easier to understand. the amount of effort it mustve taken to do this wouldve been immense i am truly thankful

Amazing work! Thank you so much. These Qualitative Analysis videos are a lifesaver for our students who are currently learning Remotely...

Thank you so much for this video! Very helpful for visual demonstration, & it makes studying and understanding this easier! 😊💕

Thank you so much. You are doing a great job 👏 👍

thanks a bunch :)

I'm getting that A* soon Ms Lina!

Lead hydroxide is amphoteric I think, it should dissolved in excess Sodium hydroxide

Please tell name of salts of aluminum sodium and calcium you used in reaction

I don't understand when you put NaOH in Al+ and Ca+, why does a reaction happens? Al and Ca are lower in reactivity series than Na. I'm sorry in advance if I'm being so dumb.

Poor results. Use conc NaOH or NH3
