Hi, in this video I'll be making magnesium chloride from magnesium metal and hydrochloric acid. Warning, hydrochloric acid is corrosive. Heat burns things. Always wear eye protection. Nobody wants a burnt eye. Paper can give you a nasty cut. To start with, I just put about 50 ml of 20% hydrochloric acid into a 250ml beaker. And I started adding short lengths of magnesium metal, in this case some ribbon. The reaction is highly exothermic so the hydrochloric acid will begin to boil. In this case it's fine because we'll be boiling down the liquid anyway. A black piece of wood turns out to be a very very useful and a few mud. After reducing down the liquid to an arbitrary amount hopefully we'll start to get crystals. However first it needs to be filtered. Gloves actually help when you were trying to handle hot glassware. However there are other ways. Gloves are kind of a final backup device to protect your hands in case of some strange bizarre accident. They're not a magic force field to protect your hands nor contamination of the thing you're trying to make. There is absolutely no reason ever to stick your fingers into a chemical mixture of any kind. With another batch of magnesium chloride far dirtier this time, I appear to boil it down to a really really close point without a crystallisation. Very interesting in fact. It's almost like it's crystallising but then we dissolve it rapidly as the very slight air currents move around the beaker. If anybody actually knows what this is caused by please leave a comment down below. After a surprisingly short time crystals are formed. Look at those spiky beauties marvellous. Next we'll need to re-desolve and then re-chrystallise this magnesium chloride to make something pure enough for a tofu. Thanks for watching.
