【題目】指出下列溶液中的溶質(zhì)和溶劑，將其填入下表中．

溶液

溶質(zhì)

溶劑

（1）生理鹽水

（2）澄清的石灰水

（3）碘酒

（4）稀鹽酸（氯化氫氣體的水溶液）

（5）高錳酸鉀溶液

（6）酒精溶液

【答案】（1）氯化鈉 水 （2）氫氧化鈣 水 （3）碘 酒精 （4）氯化氫 水 （5）高錳酸鉀 水 （6）酒精 水

【解析】對(duì)題中典型溶液的溶質(zhì)和溶劑判斷易出現(xiàn)下列錯(cuò)誤：稀鹽酸的溶質(zhì)易錯(cuò)答為鹽酸，而鹽酸本身就是溶液；碘酒的溶質(zhì)易錯(cuò)寫為碘酒，溶劑易答為“酒”，而酒本身是酒精的水溶液，因此要注意不能把溶液當(dāng)作溶質(zhì)或溶劑．
