Calculating [H+] from pOH
A sample of freshly pressed apple juice has a pOH of 10.24. Calculate [H+].
A solution at 25 °C has pOH = 10.53. Which of the following statements is or are true?
(i) The solution is acidic, (ii) The pH of the solution is 14.00 - 10.53. (iii) For this solution, [OH-] = 10-10.53M.
(a) Only one of the statements is true, (b) Statements (i) and (ii) are true, (c) Statements (i) and (iii) are true, (d) Statements (ii) and (iii) are true, (e) All three statements are true.
Chemistry Week 7 part two Dipole Dipole: Permanent dipoles= polar molecule Attraction between polar molecules with partial positive and negatives Weaker than ion ion interaction Only effective over short distances Hydrogen Bonding Not actually a bond, but very strong dipole dipole interaction Hydrogen bonding IS dipole dipole interaction Occurs in polar molecule with a polarized H, F, N, or O Hydrogen must be attached to fluorine, nitrogen, or oxygen Weaker than ion ion interaction but four to five times stronger than dipole dipole Influences largely melting and boiling point Things that can hydrogen bond are typically liquids at room temperature
