1in the question the data is insufficient either u have to give me the initial conc of the acid or the dissociation cons of the acid
plz correct me if i am wrong
Lemon juice normally has a pH of 2.If all the acid in the lemon juice is citric acid and there are no citrate salts present, then what will be the citric acid concentration [HCit] in the lemon juice?(Assume that only the first hydrogen of citric acid is important)

1conc. is zero as it has nearly fully dissciates thinking so but agreeing with gagar
1the initial concentration is 0.13 molar and the concentration at the time of equilibria is 0.12 molar
3sir please give me ur soln.
and also doesnt the conc of [HCit] isnt zero as stated by rahul
1H+=10-2
→OH-=10-2
using eq for charges→H+=OH-+[Cit-]
[Cit-]=10-2now [HCit]at equilibria can be found with
the help of Ka values then initial concentration can be found with the help of mass eq
[HCit]0=[HCit]+[Cit-]
