【題目】溶液對人類的生產(chǎn)、生活都有很重要的意義。下列關于溶液的說法或做法錯誤的是(

A.夏天喝的汽水不是溶液

B.蛋湯太咸,加水稀釋后口味變淡

C.魚塘中放置噴泉水泵的作用是增加水中氧氣的溶解量

D.涼茶水是均一、穩(wěn)定的混合物

【答案】A

【解析】

試題分析:溶液具有均一性和穩(wěn)定性,一種溶劑里可以同時溶解多種溶質(zhì)。A.汽水中溶解了二氧化碳氣體、糖等物質(zhì),汽水具有均一性和穩(wěn)定性,屬于溶液,A錯誤;B.蛋湯太咸是因為食鹽的濃度過大,加水后食鹽質(zhì)量不變,溶劑量最大,溶液的濃度變稀,正確;C.溶質(zhì)與溶劑的接觸面越大,溶質(zhì)溶解的越多,C正確;D.涼茶水是均一、穩(wěn)定的混合物,屬于溶液,正確。故選A
