Thallium(I) hydroxide is a strong base used in the synthesis of some organic compounds. Calculate the pH of a solution containing 2.57 g TlOH per liter.

Question

I got 1.44 but I'm pretty sure that's wrong?

Answer 1

But that's close for the pOH.
mols TlOH = grams/molar mass = ?= mols OH^-
pOH = -log (OH^-)
Then pH + pOH = pKw = 14. You know pK2 and pOH, solve for pH.
