Hello guys! today I'm going to show you a pack of unique chemical experiments with thionyl chloride
Thionyl chloride is a colorless , fuming in the air liquid
with a suffocating smell due to the fact that it always produce sulfur dioxide and hydrogen chloride
that's why it has the number 4 in the NFPA rating that means the highest health hazard
Believe me, the bromine spilled in the laboratory is nothing compared to what will happen if you pour out thionyl chloride
thionyl chloride completely hydrolyzed by water produce sulfur dioxide and hydrogen chloride
When heated above the boiling point, thionyl chloride decomposes into sulfur chlorides
because of sulfur dichloride we can see red-cherry coloration
The resulting sulfur chlorides are also hydrolyzed
Thionyl chloride can be used to dehydrate salts. A good example the reaction with cobalt (II) chloride hexahydrate
during the dehydration the color of cobalt chloride varies from rose red to violet.
This reaction is accompanied by a marked decrease in temperature
Now if we add water again, then the color begins to change in the opposite direction from violet to rose-red
Now let's have a look at the series of beautiful and dangerous reactions between thionyl chloride and some metals
Thionyl chloride reacts violently with a lot of metals, like this metallic potassium ignites upon contact with it
to initiate the reaction with metallic lithium, you have to add a just a little bit of water
Here you can see the particles formed of colloidal sulfur now the reaction with metallic barium
Extremely violent reaction with Samarium metal
And finally quite nice reaction with titanium metal
