IPA: /ɪnˈsoʊl.jə.baɪlaɪzd/
KK: /ɪnˈsɒljʊbaɪlaɪzd/
Describing something that has been made unable to dissolve in a liquid.
The chemical was insolubilized to prevent it from mixing with water.
Insolubilized → It is formed from "in-" (meaning not) and "solubilis" (from Latin, meaning able to be dissolved) and the suffix "-ized" (meaning to make or become). The word means to make something not able to be dissolved.
Think of 'not' ('in-') being combined with 'able to be dissolved' ('solubilis') — that's why 'insolubilized' means something that cannot be dissolved.
