二氧化碳在常溫常壓下為無色無味氣體，溶于水和烴類等多數(shù)有機溶劑，二氧化碳是碳氧化合物之一，是一種無機物，不可燃，通常也不支持燃燒，低濃度時也不可以。它也是碳酸的酸酐，屬于酸性氧化物，具有酸性氧化物的通性，其中碳元素的化合價為+4價，處于碳元素的比較高價態(tài)，故二氧化碳具有氧化性而無還原性，但氧化性不強。一定條件下，二氧化碳能與堿性氧化物反應(yīng)生成相應(yīng)的鹽，向澄清的石灰水中加入二氧化碳，會使澄清的石灰水變渾濁，生成碳酸鈣沉淀，此反應(yīng)常用于檢驗二氧化碳，由于碳酸氫鈣溶解性大，長時間往已渾濁的石灰水中通入二氧化碳，可發(fā)現(xiàn)沉淀漸漸消失。
