Now how soluble is methylphenidate hydrocloride in water?
Is info A) correct?
What does info B) mean?

Both A) and B) can be found on the internet.

How many mg methylphenidate HCl can be dissolved in how many ml H20?

[superdupernaut]

B appears to be incorrect, at least in reference to the hydrochloride salt.

Ok, also SWIM also had doubts about it not being about the HCl version.

How correct is A?
