What the actual fuck. Why is it doing this.

>>8630241
There.

>>8630241
google shows Bismuth Iodide (Bil3)

>>8630247
Thanks. I was racking my brain trying to figure out if it was a typo. It didn't occur to me that it could be a naming thing and not an element. I should have checked Google first I suppose.

>>8630247
Or apparently Bismuth itself had slipped from my memory

BiI3(s) <--> Bi3+(aq) + 3I-(aq)
K_sp = [Bi3+][I-]^3 = (1.32E-5)(3.96E-5)^3 = 8.20E-19

read your fucking book

>>8630260
I know how to do it I just couldn't remember what Bi was.

Also you rounded a number. A fatal mistake. Thanks for the help though

>Also you rounded a number. A fatal mistake.
8.19708... * 10^(-19) in 3 significant figures. And even the arbritrary rule shitty instructors have on rounding if and only if it results in an even decimal applies.

>>8630265
constants aren't special enough for my autistic brain so I round despite being inappropriate

Alright mate. I prefer truncating, even if it is occasionally less acurrate.
