    35.(2025·福建省)我国古代劳动人民因地制宜生产食盐。如《明史》记载:“解州之盐,风水所结;闽粤之盐,集卤。”
    (1)解州之“盐”指池盐,即自然条件下盐湖结晶得到的食盐(含Na2SO4等杂质),常产于气候干旱地区。
    ①池盐属于 (填“纯净物”或“混合物”)。
    ②盐湖遇到西北风(冷空气)或南风(热空气)时,均会出现“一夜浮华”(析出大量晶体)的现象。所得晶体中,NaCl含量较高的自然条件是 (填“西北风”或“南风”),理由是 。(已知:Na2SO4和NaCl的溶解度曲线如图所示)
    (2)闽粤之“盐”指海盐,其生产工艺(集卤):海水先经风吹和日晒获得较浓卤水,再煎制得食盐。生产时,古人用不同浓度的食盐水处理过的石莲子(一种植物果实)和竹筒制成莲管秤(如图A所示),用来检验卤水的浓度是否达到煎制要求。
    ①“集卤”工艺不采用直接蒸煮海水的方法提取食盐,其原因是 。
    ②处理石莲子时,需配制饱和食盐水,其操作是 。


    ②分子中无甲基且苯环上只有两个取代基;
