Predict titration curve for titration of Na 2 CO 3 & HCl.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Na 2 CO 3 + HCl 
NaHCO 3 + NaCl
pH 1 = Half equivalence point with respect to 1 st neutralisation = 
( solution will be a buffe consisting of equal amount of 
& 
)
= 
( amphiprotic anion)
NaHCO 3 + NaCl 
H 2 CO 3 + NaCl
pH 2 = Half equivalence point with respect to 2 nd neutralisation = 
( solution will be a buffer consisting of equal amount of 
& H 2 CO 3 )
= 1/2 ( 
– log C) ( weak acid)
