Morphology
The noun phrase is directly compositional: 'white' simply describes the color/form of 'arsenic', so a B1 learner who knows both words will understand it refers to a white form of arsenic (arsenic trioxide) and can reasonably infer it is a poisonous substance. The adjective+noun composition is a common, cross-linguistic pattern, making the meaning transparently derivable from the constituents.
Etymology
White arsenic is named for its look: a fine, white powder made from the element arsenic. Because people used this white powder as a 'poison' and in glass making, the name came to mean the toxic chemical arsenic trioxide.
