    I've always gotten grey ppt, I never knew why. This video helped me so much. I did this test like 4-5 times and never got the silver mirror. This is exactly what I was looking for. Thank you so so much.

    very clear and helpful, straight to the point, appreciate this a lot, thx. i now know what are the warning sign to look out for while i use the reagent. also if it's possible could u help to explain why in excess NAOH and NH3, a grey ppt will form?

    Sir, can't we get the silver mirror by heating the test tube instead of placing it in that beaker

      I don't think so... Temp will be too hot. I'll try it and let you know.

      No because there will be disturbances causing the mixture ...but in a water bath there will be uniform heat supply

    • @milaanbosco7724

      Can't heat directly because of the formation of silver nitride ( Ag3N) which is highly explosive. So a water bath is more appropriate.
