Solid-Liquid Phase Equilibria for the Ternary System KN[O.sub.3] + K[H.sub.2]P[O.sub.4] + [H.sub.2]O at 283.15, 298.15, and 313.15 K This change has corrected the oxygen, which now has two atoms on both sides. The arrangement forms a regular octahedron. The choice of a salt in the lab is determined primarily by how acid or basic the chemical is (the pH), the safety of the ionized form, the intended use of the drug, how the drug is given (for example, by mouth, injection, or on the skin), and the type of dosage form (such as tablet, capsule, or liquid).
