Hello All,

If I'm doing a liquid-liquid separation, and during the separation of the acid,  instead of using 3M Na OH (aq), I use 5M NaOH -- would this wreck my experiment?

I don't think so since it's just more concentrated per Litre (more moles).  Is there anything I'm missing?

I wouldn't think it would matter, unless the acidic compound contains a base labile group such as an ester, even then I doubt you will see any significant difference between 3M and 5M NaOH.

Thanks for the help

That being said, diluting 5 M solution to 3 M means just adding some water.

I misread this as "used".

As Borek says it is better to follow the procedure, even if it's just for economic reasons. Less reagent means less money spent.

If you've already done it it never hurts to do a quick comparison to put your mind at ease..
