Questions asked by several people about our sodium sulfide testing of paint for lead1 make us feel we might wisely add several words of caution about the stability of the prepared solution.
Sodium sulfide solutions deteriorate fairly rapidly with age, especially on exposure to air. For this reason, it is suggested that people using the procedure check the odor of the sodium sulfide solution tlley are using, to make sure the odor of hydrogen sulfide is detectable.
