To determine the equivalent weight of NaCl, we can follow these steps:1. Understand the Concept of Equivalent Weight: The equivalent weight of a substance is defined as the molecular weight divided by its valency. The valenc
From equation (1) and (2) 1 mole of AgNO3 is equivalent to 1 mole of NaCl and 1 mole of AgNO3 is equivalent to 1 mole of NH4SCN. Therefore 1 mole of AgNO3 is equivalent to 76.12 g of NH4SCN. Then 0.1 mole of AgNO3 is equivalent to 7.612 g of NH4SCN. ...
我也觉得你写错了,应该是equivalent weight中文解释为:当量当量:当量指与特定或俗成的数值相当的量;化学专业用语,用作物质相互作用时的质量比值的称谓。化学专业用语:在任何化学反应中,物质的质量比等于它们的当量比。泛 当量指化学方面的当量术。诸如 当量、克当量、当量浓度、酸碱盐当量、电化当量 等。根据定组成...

In the laboratory, NaCl, tap water and distilled water are used for measuring conductivity and ESDD. In addition, different sizes of glass plates are used as an insulating medium. A conductivity-measuring instrument (Cond 300i) is used to measure the conductivity of the salt-solution. Based ...
When copper wire is placed in a solution of NaCl no reaction occurs. Why is this? What is the molar concentration of cations and anions for 2.2 M aluminum chlorate? Why is it important that the endpoint of a titration match the equivalence point? Why is a buffer solution added in EDTA...
Just before the study end, GFR was estimated in conscious mice using the transcutaneous decay of retro-orbitally injected FITC-sinistrin (10 mg/100 g body weight dissolved in 0.9% NaCl), as previously described58. Plasma cystatin C was also measured by ELISA at the study end (BioVendor...
The immersion of freshly collected adults into saline solution (NaCl, 0.9%; pH 1.0) resulted in 100% mortality of worms within a 10-minute period. At pH 7.0, mortality was 58% after 270 minutes. At pH 2.2, which approximates the usual ab... H Eiler,W Baber,WA Lyke,... - 《Americ...
