1. Your task is to prepare a buffer solution of 1.00 L of 0.250 M acetic acid and solid sodium hydroxide. Start by writing the equation for the reaction that will form the buffer (hint: you must have both acetic acid and acetate ion in the solution; where will the acetate ion come from? Neglecting the volume change on addition of NaOH (MM 40.0 g/mol), what mass is required to produce a buffer of pH 3.75? What pH will the...

You have been tasked with making a 1.50 L buffer solution with 0.250 M in HF and 0.250 M in NaF so all of your experiments will have a constant pH value. Under no circumstances can your pH leave the range of 3.2-3.7. A clumsy professor, Dr. Urkel, walks by and accidentally spills 0.100 moles of solid NaOH into your solution. Will your buffer be able to withstand the addition and still stay in the range? Calculate the new pH...
