Potion Id

So can someone help me
I would like to put a potion on an invisible armour stand but im not sure how to do it this is the command im typin in
/replaceitem entity @e[type=armor_stand,r=2.5] slot.armor.head minecraft:potion 1
I'm pretty sure the last number represents the type of potion and i also saw a website with potions ids
http://minecraft-ids.grahamedgecombe.com/potion-calculator
but it just keeps on giving me uncraftable potions ( error blocks )

 

thats outdated

 

/replaceitem entity @e[type=armor_stand,r=2.5] slot.armor.head potion 1 0 {Potion:regeneration}

replace the indicated area with one of the items from this list

if you're going to be doing some more complicated stuff with JSON you might want to put quotes around "Potion" and "regeneration" (or whatever you put there)

or maybe not

i dunno

unfamiliar with 1.9+ JSON

 

thanks a lot it worked also im just trying to make a cool shop xD and i wanted to have potions on shelfs
