help making interesting compounds

[jordehwa]

I am very interested in in elements and there compounds.

so as i collect elements i also take some of that element and make some of its compounds for sample collecting. it may not sound like it but its a really fun hobby for me.

 

 

 

But now i want some different acids so i can make more compounds.

 

I am done with common acids like Hydrochloric acid, acetic acid, sulfuric acid, and citric acid.

 

So here is my question does anyone know of some acids i could get to make some compounds for my hobby.

 

Here is two examples of the kind of acids i am looking for

Lactic acid and gluconic acid.

 

So if anyone knows some acids i can use to make cool compounds please let me know thank you.

 

 

ps: I know its alot but before you answer please read the hole thing.
