Aqueous solutions?

Question

If an aqueous solution has [OH] = 3.0 x 10-11 mol/L, would the solution be:
a. An acidic solution
b. A basic solution
c. A neutral solution
And why?

Answer 1

pH + pOH = 14

so pH = 14 - pOH

pOH = -log {OH} = 10.5

so pH = 14 - 10 = 3.5

you tell me. is a solution with pH = 3.5 acidic, basic or neutral?


and for all of you rating me with the thumbs down, thanks anyway but this is the right answer... :)

Answer 2

the previous poster is real. The question is unusual as ideas are actually not expressed with chemical formulae (i did not think of) i think for an aqueous answer you could desire to do something like: H20 + Na+ + Cl- to coach how salt varieties ions in water however the non-aqueous ideas will require slightly learn. (issues like fat-soluble supplements and hormones, yet ten? chuffed i'm not you!) :-)

Answer 3

dotn listen to first respondent, its wrong

the answer is acidic and here's why:
if u take the -log [OH], you get 10.5
however, that is on a scale of pOH, the scale we use is pH
to convert from pOH to pH, just do 14 minus 10.5 and ur answer is 3.5, which is an acidic solution

Answer 4

If the concentration of OH- is less than 10-7M, then the solution is acidic.

Answer 5

Basic. Having extra OH's is the definition of basic.
