Answer 2

Ok so what do you do first

Answer 3

i dont know...

Answer 4

So what have you learned about this in your class?

Answer 5

you're given the pH as 11.8

you can find the pOH by subtracting 14 - pH
from there, OH concentration is [OH] = 10^(-pOH)

Answer 6

im just really bad at this type of stuff and I don't get any of it, it don't make sense to me

Answer 7

you need the pOH first

subtract 14 - pH to get pOH

your pH is 11.8, so your pOH is 14 - 11.8 = 2.2

now, plug pOH = 2.2 into the formula [OH] = 10^(-pOH) to get your OH concentration

Answer 8

ok
