Production
The reaction between ammonia water and praseodymium(III) nitrate produces praseodymium(III) hydroxide:[2]
- Pr(NO3)3 + 3 NH3·H2O → Pr(OH)3↓ + 3 NH4NO3
Chemical properties
Praseodymium(III) hydroxide can react with acid and produce praseodymium salts:
- Pr(OH)3 + 3 H+ → Pr3+ + 3 H2O

gollark: It's far below average site size, but I don't know how or why.
gollark: Your thing pulls in an entire Lua VM for about five lines of JS, soooo...
gollark: I think a big reason for inefficiency is that some sites seem obsessed with shipping big images with their content even when it's not meaningful or helpful.
gollark: I've designed my website to be very lightweight, though, so it's reasonably good for people on slow connections and loads very fast.
