DISCUSSION

The density of the test item Sulfonium, tris(4-chlorophenyl)-, salt with 5‑benzoyl‑4‑hydroxy‑2‑methoxybenzenesulfonic acid (1:1) was calculated as 1.4689 ± 0.0003 g/cm3at 20 ± 0.4 °C, which is the mean of two values. Precision of the value is given as maximal error of a single determination.
