Make 1.00 L of 1.0 M buffer pH 6.2. How much of each component do you need to use? You have NaHmalonate and 10.0 M NaOH. The pka of malonate is 5.69 and the MW is 126.1 g/mol.

(NaHmalonate: ..........g, NaOH: ......... mL, H2O: ........mL). 

Use the Henderson-Hasselbalch equation, 

n_OH- = n_A-

, and to first find n_HA 

use the equation 

n_total = n_HA + n_A-

Answer rating: 100% (QA)

The buffer conc is 10 M The volume required 10L Therefore the moles of NaHmalonate conc x volume 1o ... View the full answer
