Which solution is a buffer? which solution is a buffer? a solution that is 0.200 m in h2so4 and 0.200 m in na2so4 a solution tha
t is 0.200 m in h3po4 and 0.200 m in nah2po4 a solution that is 0.200 m in h3po4 and 0.200 m in nabr a solution that is 0.200 m in h3po4 and 0.200 m in hbr?
Buffer is formed from weak acid and its salt with strong base (its conjugate base) So the only one correct answer is : 0.2 M H₃PO₄ and 0.2 M NaH₂PO₄ While all other choices are incorrect
Water would have a much lower boiling point much like its other hydrides and it would loss its ability to dissolve polar substances plus it couldn't form water columns so no more cohesion between water molecules
