On wikipedia (https://en.wikipedia.org/wiki/Iron(III)_chloride) it says:
The ferric chloride test is a traditional colorimetric test for phenols, which uses a 1% iron(III) chloride solution that has been neutralised with sodium hydroxide until a slight precipitate of FeO(OH) is formed.[26] The mixture is filtered before use. The organic substance is dissolved in water, methanol or ethanol, then the neutralised iron(III) chloride solution is added—a transient or permanent coloration (usually purple, green or blue) indicates the presence of a phenol or enol.
So what materials do I need? Ferric chloride (saw it for sale on Amazon) and Sodium Hydroxide (I can check). Then how do I exactly neutralise it to satisfy the conditions and what do they mean by filter. Remove solids? With what?
I have a physics background but almost no chemistry background...
thanks
