水用途與合成方法

概述

水，化學式為H2O，是由氫、氧兩種元素組成的無機物，無毒，可飲用。在常溫常壓下為無色無味的透明液體，被稱為人類生命的源泉。水是地球上最常見的物質之一，是包括無機化合、人類在內所有生命生存的重要資源，也是生物體最重要的組成部分。

形態

水具有多種形態，包括超臨界流體、超固體、超流體、費米子凝聚態、等離子態以及最常見的固態，液態和氣態；根據組成水分子的氫元素的不同，水又分為重水和普通水；水中不同的溶質又會使水表現出不同的特性。

理化性質

水是人類生存不可缺少的主要營養素。隨著人們生活水平的不斷提高，人們越來越關注飲用水的質量及其與健康的關系。其中，很多研究者開始關注不同水質對健康的影響。純凈水作為一種直接飲用水，受到了越來越多的關注。純凈水是一種極低硬度、極低礦物元素水平的軟水，一般為弱酸性。純凈水經過凈化處理，菌落數、氰化物等有害物質含量明顯降低。

用途適  于與E-TOXATE試劑盒ET0100、ET0200和ET0300共同使用,作為pH調節液。避免污染。

用途  主要用于RNA沉淀的溶解
