Where to find 100% NaCl for the mash water?

[Elysium]

I understand that it is table salt that we use for cooking...but there are several types. I am wondering which one is pure 100% NaCl that is for brewing?

Does anyone know?

The danger with 'Table Salt' is that in North America it contains iodine which is a yeast poison. To get around that most brewers use Kosher salt which does not contain iodine. Another possible source migt be the 'purified' salt used by sausage makers.

You can use kosher salt which does not contain any additives

Or you could buy the salt not labeled as "iodized." It's on the supermarket shelf right next to the one labeled iodized.

Why are you adding NaCl? Sodium is not required and too much (100ppm+) can be a problem. Na+ doesn't really do anything in the process and if you want to add Cl- the Calcium salt CaCl2 is a much better choice. If for some reason you want to add NaCl use a pickling salt or a brand of Kosher salt without additives.

I only wanna add 1,2 g....I already have all the desired amount of the rest of the minerals. It is a little bit of Cl and Na that I'd like to add...to reach Cl:97, Na: 16.8. I am wondering if we need Na at all in a brew......
