Answer #1
use Henderson-Hasselbach equation
pH = pKa + log [A-] / [HA]

given:
pH=2.09
citric acid pka =3.09
mono sodium citric acid is salt [HA]
w are looking for [A]

mono sodium citric acid is salt [HA]
from henderson equation is
pH = pKa + log [A-] / [HA]

plug in values:

2.09=3.09+ log [A-] / [HA]
log [A-] / [HA]=2.09-3.09
log [A-] / [HA] =-1

concentration is 0.1
