Substaint cheimiceach

Is éard is substaint cheimiceach ann ná cineál damhna a bhfuil comhdhéanamh ceimiceach seasmhach aige agus airíonna saintréitheacha. [1] Is féidir le substaintí ceimiceacha a bheith ina substaintí simplí ( substaintí atá comhdhéanta de dúil cheimiceach amháin ), [2] comhdhúile ceimiceacha, nó cóimhiotail.

Tá dhá fhoirm dhifriúla den tsubstaint cheimiceach íon chéanna ag gal uisce agus uisce leachtach, is é sin, uisce.
