Question- In lab you are asked to determine the concentration of a solution of a monobasic base (B) (balanced equation shown) by titration. You are provided with the appropriate tools, pure, dry, solid sodium carbonate for standardization and aqueous HCl, which is approximately 0.1M. Given the data shown, what is the concentration of the base?
B + HC l---> HB+ + Cl-
2HCl + Na2CO3 ---> H2O + CO2 + 2NaCl
Standardization of HCL-
Mass Na2CO3 is .2210g
Initial volume HCL is 2.13 mL
Final volume HCl is 40.93 mL
Titration of 25.00 mL of B solution
Initial volume HCl is 1.08 mL
Final volume HCl is 29.25 mL
