其他信息

  • 1.将本品垂直放于1升的容量瓶上。
  • Acetic acid is used in biochemical and molecular biological as a buffer when combined with sodium acetate in a specific buffering range fo pH 3.6 - 5.6. Acetic acid also is used in organic synthesis for the production of different acetates and acetyl compounds and as a precursor of polyvinylacetate and cellulose acetate.
  • 每瓶安瓿可稀释成一升的滴定液
  • 具有刺激性特殊气味,有腐蚀性。
  • 2.用附带的小工具从上至下刺破薄膜,使浓缩液流入容量瓶中
  • 使用方法:
  • 有刺激性气味。有腐蚀性,对皮肤有刺激痛,发水泡。其蒸气有毒,并易着火。纯的无水乙酸(冰醋酸)是无色的吸湿性液体,凝固点为16.7℃(62℉) ,凝固后为无色晶体。能与水、乙醇、乙醚、四氯化碳和甘油混和,难溶于二硫化碳。凝固时体积微缩。
  • 注:本包装为浓缩液,是用来稀释成1升的分析滴定液。稀释后的浓度即为标签上所示浓度。(在允许的不确定度区间之内)
  • 3.取适量的蒸馏水润洗本产品的容器,并使之流入到容量瓶中,直至加到一升容量瓶的刻度处
