(Updated specification ASTM D 1141-98 (2003) Formula a, Table X1.1, Section 6)

DESCRIPTION:

  Sea-Salt is a simulated sea salt mix containing elements found in natural sea water in quantities greater than 0.0004%. Sea Salt is granular and colorless. Mixture contains U.S.P., N.F. and High Grade Commercial Salts.

DIRECTIONS:

  Dissolve 41.953 grams Sea-Salt in water with enough water added to make one liter total solution, or dissolve 5 1/2 ounces (156 grams)Sea-Salt in water, then add enough water to make 1 gallon total solution of synthetic sea water. After mixing, adjust pH to 8.2 using 0.1 N solution of sodium hydroxide or hydrochloric acid.

SPECIFICATIONS:

  Meets American Standard for Testing and Materials D 1141-52, Formula a, Table 1, Section 4 (basic formula without added heavy metals) for duplicating ocean water and also updated Standard ASTM D 1141-98 (03) Table X1.1, Section 6.
