水 用途与合成方法
概述水,化学式为H2O,是由氢、氧两种元素组成的无机物,无毒,可饮用。在常温常压下为无色无味的透明液体,被称为人类生命的源泉。水是地球上最常见的物质之一,是包括无机化合、人类在内所有生命生存的重要资源,也是生物体最重要的组成部分。
形态水具有多种形态,包括超临界流体、超固体、超流体、费米子凝聚态、等离子态以及最常见的固态,液态和气态;根据组成水分子的氢元素的不同,水又分为重水和普通水;水中不同的溶质又会使水表现出不同的特性。
理化性质水是人类生存不可缺少的主要营养素。随着人们生活水平的不断提高,人们越来越关注饮用水的质量及其与健康的关系。其中,很多研究者开始关注不同水质对健康的影响。纯净水作为一种直接饮用水,受到了越来越多的关注。纯净水是一种极低硬度、极低矿物元素水平的软水,一般为弱酸性。纯净水经过净化处理,菌落数、氰化物等有害物质含量明显降低。
用途 适于与E-TOXATE试剂盒ET0100、ET0200和ET0300共同使用,作为pH调节液。避免污染。
用途 主要用于RNA沉淀的溶解
