A student must make a buffer solution with a pH of 1.00.
Determine which weak acid is the best option to make a buffer atthe specified pH.
formic acid,Ka = 1.77 x 10−4,2.00 M
sodium bisulfate monohydrate, Ka = 1.20 x10−2, 3.00 M
acetic acid, Ka = 1.75 x 10−5,5.00 M
propionic acid, Ka =1.34 x 10−5,3.00 M
Determine which conjugate base is the best option to make a bufferat the specified pH.
sodium acetate trihydrate,CH3COONaâ‹…3H2O
sodium propionate, CH3CH2COONa
sodium sulfate decahydrate,Na2SO4â‹…10H2O
sodium formate, HCOONa
The final volume of buffer solution must be 100.00 mL and the finalconcentration of the weak acid must be 0.100 M.
Based on this information, what mass of solid conjugate base shouldthe student weigh out to make the buffer solution with a pH of1.00?
mass = Answer g
Based on this information, what volume of acid should the studentmeasure to make the buffer solution?
volume = Answer mL
