how to acheive 50ppm sodium in 120z

[grathan]

If I was at 0ppm. Expressed in grams(or grains), how much canning salt would it take to raise 12oz of liquid by 50ppm sodium?

About .03g.

Thanks.

1 gram of NaCl has 160 ppm chloride and 104 ppm sodium when disolved in 1 gallon of water. Since you only want 12 oz of liquid, 1 gram would give you a concentration of 104ppm x (128/12) = 1,109.333ppm. Too strong! So we solve for the reduced amount needed as follows:

50ppm / 1,109.333ppm = x gms / 1 grams

Solving for x gives .045 grams.

Yep! the 0.045 g is what I got with Bru'n Water. I was scratching my head over the 0.03 g answer above.
