What is the difference between the following two reactions, if any? I’m assuming equal amounts of both here.
NaOH(solid) + H2O -> lye(aq)
H2O + NaOH(solid) -> lye(aq)
Both reactions are exothermic, and both seem to be the same to me.
However, everywhere, including in MSDS sheets, you will read that you should always add the solid sodium hydroxide to the water and never the other way round, because explosion risk (???)
I’ve tried both ways and there are no explosions, and the end result seem to be the same. Am I missing something? Or is this one of those internet myths that are simply wrong?
