Forming and Breaking Bonds
And here are the potential answers: pH 12.4, eh?
This problem ought to be pretty…basic. [Ph 12.4 shown on Ph scale]
Okay, in all seriousness, we know this subject can be tough, but as far as chemistry problems [Boy with chemistry formulas on a chalkboard]
go, this one’s not too bad.
The key equation we need to remember for solving this problem is pH plus pOH equals 14.
This equation is always valid for any aqueous solution, so whenever we know the pH, we can [Hand points to pH and pOH hiding behind bushes]
easily find the pOH.
In this case, the pH is 12.4, so our equation becomes 12.4 + pOH = 14.
A little simple math, and boom.
Our pOH has to equal 1.6, which is answer choice B.
That problem was so basic, we’re surprised it wasn’t wearing UGG boots and drinking [Man wearing ugg boots and takes sip of pumpkin latte]
