CaOH2et
CaOH2et is not a standard or widely recognized chemical name or formula in major chemical databases. The designation appears likely to be a typographical error or a shorthand that is ambiguous without additional context. It could be intended to refer to calcium hydroxide (Ca(OH)2), calcium ethoxide (Ca(OEt)2), or a solvated/adduct form such as Ca(OH)2·Et where “Et” stands for an ethyl group. Because of this ambiguity, a precise, single article for CaOH2et cannot be given without clarification.
If the intended compound is calcium hydroxide, Ca(OH)2 is an inorganic base that appears as a white,
If the intended compound is calcium ethoxide, Ca(OEt)2 is an organometallic compound that is moisture sensitive
In summary, CaOH2et likely requires clarification to determine whether it refers to Ca(OH)2, Ca(OEt)2, or another
