1conc. is zero as it has nearly fully dissciates thinking so but agreeing with gagar
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)

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
11the 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-]
