Universal indicator goes from red (pH 4) to violet (pH10) as the pH of a substance changes. Adding NaOH to water starts the solution off at pH 8-9 (blue). When dry ice is added to water it forms carbonic acid, and lowers the pH, which is the reason for the color changes.
The mixture then bursts into flame, producing a white smoke together with the iodine vapour, and leaving a glowing, white residue of aluminium iodide. Teaching notes. It is important to try this experiment before doing it as a demonstration, as different samples of aluminium powder can react differently.
Nov 01, 2019· How to Perform the Nitrogen Triiodide Demo . The first step is to prepare the NI 3.One method is to simply pour up to a gram of iodine crystals into a a small volume of concentrated aqueous ammonia, allow the contents to sit for 5 minutes, then pour the liquid over a filter paper to collect the NI 3, which will be a dark brown/black solid.However, if you grind the pre-weighed iodine with a
Mar 03, 2020· When I think back to my own childhood and school days, I don’t remember any chemistry experiments until secondary school, which is a shame because there are so many wonderfully visual easy chemistry experiments for kids that can be done at home or in school with young children..
