kinda off subject but does anyone know the PKA of sodium cloride in spring water?

[Osiris Ra]

Im mixing sea salt and water and basifing it with sodium hydroxide and was wondering at what PH would I hit the sodium chloride to make it perciptate?

I dont think that is happening. Your sodium chloride will be dissolved in water, and so will your lye, until you add so much that the lye cant dissolve anymore, but the sodium chloride salt will stay dissolved. What are you trying to do?

Sodium chloride does not have a pka. pka (or pkb) values only apply to substances that behave as weak acids and bases. Not salts, strong bases and strong acids.

The other chlorides in the sea salt seem to perceptate at different PHs why wouldn't Sodium chloride?

How do you know that? Which other chlorides you say are precipitating at what pH?

Have a look on one of the nano reef forums there is a lot of information on saltwater chemistry. Ph plays a large role in what will and won't dissolve / precipitate.

Salt water chemistry is massively important in a reef tank and there is a lot of detailed science available if you are willing to look.
