Bottled Water - Not Aquarium Related

[rtparty]

The other day I was given a bottle of “Pure” water. It states purified water with minerals added for taste. We’ve all seen this. But it got me thinking so I looked at the “ingredients” of this pure water.

Purified water, sodium bicarbonate, calcium chloride.

So my chemistry question is: if I wanted to replicate this bottle of water how much sodium bicarbonate and calcium can I add and not worry about precipitation?

They could technically add one drop of each to a 1L bottle and they wouldn’t be lying about the ingredients. But would that actually impact the “taste” of the water?

It doesn’t take much to improve the taste of totally pure water.

One could calculate how much could dissolve, but it would be more than the solubility limit of calcium carbonate, which is about 15 mg/L, because most of the bicarbonate stays as bicarbonate rather than carbonate.

Yup, make your own and save money or sell it, give it a fancy name and be rich.

Don’t give away my plan!

Thanks Randy. Just a curious mind after seeing the ingredients
