assuming a sufficiently long and efficient fractionating column is used, what is the boiling point of the azeotrope being distilled?

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

the answer is the first option

explanation:

just googled it m8. not that hard

lol

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
