Lemon juice normally has a `pH` of `2`. If all the acid 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) `HCithArrH^(+)+Cit^(-)`, `K_(a)=8.4xx10^(-4) mol L^(-1)`
