C, is expected to be a) exactly equal to 7.0 b) approximately equal to 7.0 c) significantly larger than 7.0 d) significantly smaller than 7.0 e) undefined, because the concept of ph does not apply to solutions of salts 3) Hypoiodous acid (HOI) is a weak acid, with K a = 3.5 x 10-8 (at T = 25. C). OI - ion is a) a weak acid b) a strong acid c) a weak base d) a strong base e) None of the above, as ions have no acid or base properties 4) Which of the following is the strongest oxyacid? a) HIO 2 b) HIO 3 c) HBrO d) HBrO 2 e) HBrO 3 5) Consider the following three aqueous solutions Solution A Solution B Solution C moles of HClO 2 (chlorous acid) moles of NaClO 2 (sodium chlorite) dissolved in water, with final volume V = ml moles of HClO 2 (chlorous acid) moles of NaOH (sodium hydroxide) dissolved in water, with final volume V = ml moles of HClO 2 (chlorous acid) moles of NaCl (sodium chloride) dissolved in water, with final volume V = ml Which of the sbove solutions is a buffer solution? a) Solution A only b) Solution B only c) Solution C only d) Both solution A and solution B e) Both solution A and solution C 3
