What volumes of 0.200 m hcooh and 2.00 m naoh would make 500 ml of a buffer with the same pH as of one made from 475 ml of 0.200 m benzoic acid and 25 ml of 2.00 m naoh?
In general buffer the Henderson/Hasselbach equation is valid to use:pH = pKa -log [(Ca)/(Cb)]In which:* Ca = concentration of weak acid (benz. or formic.acid) and* Cb = conc'n of their respective conjugated bases (benzoate and formiate)From tables it is found: pKbenz.acid = 4.20 and pKformic.acid = 3.80pHbenz.acid,sol'n = 4.20 - log[(475*0.200-25*2.00)/(25*2.00)] == equal pH values == pHformic.acid sol'n = 3.80 - log[(Va*0.200-Vb*2.00)]/(Vb*2.00)]in which Va + Vb = 500 mL of the (new) HCOOH/HCOO- buffer* Va = volume of the formic acid sol'n (HCOOH, in mL) and* Vb = volume of the (2.00M) NaOH sol'n.The rest is calculation. Outcome:equal pH values: pH = 4.246- log [(Va*0.200-Vb*2.00)]/(Vb*2.00)] = 4.246 - 3.80 = 0.446[(Va*0.200-Vb*2.00)]/(Vb*2.00)] = 0.358Va*0.200/Vb*2.00 - 1 = 0.3580.100*Va/Vb = 1.358Va = 13.58*Vb and with Va + Vb = 500 it comes to:Va= 465.5 mL and Vb = 34.5 mL
What volume of base is needed to neutralize a strong acid?
Use this to analyse the unkown and variables:Ca*Va = Cb*Vb in which:C = concentration (mol/L = mmol/mL)V = Volume (L or mL)subscripts: 'a' = acid, 'b' = baseWanna know Vb ? well find the other three variables to calculate: (Ca*Va)/Cb = Vb (with the same unit as used for Va)
