等浓度碳酸氢钠和醋酸钠2种溶液的pH大小比较章新阳*(浙江省临安市昌化中学 浙江临安 311321)摘要 利用Excel对相同浓度的NaHCO3溶液、CH3COONa溶液中离子浓度的精确计算,得出相同浓度的2溶液中,水解程度一定是HCO-3>CH3COO-,但不能仅通过水解程度大小来得出pH(NaHCO3溶液)>pH(CH3COONa溶液)的结论,2溶液的pH大小还...
The electrode is connected to the probe through a saline bridge. The diaphragm may be a thin sheet of PTFE. The partial pressure of CO2 is measured from the pH of an NaHCO3 solution with which it is in equilibrium.
(THEORYOFACID-BASE)1 §3.3酸碱理论 概述 1663年波义耳(R.Boyle)提出酸碱概念。1889年阿累尼乌斯提出酸碱电离理论。1905年富兰克林酸碱溶剂理论。1923年布朗斯特和费莱(T.M.Lowry)几乎同时各自独立地提出了酸碱的质子理论。同年，路易斯提出了酸碱的电子理论。1963年皮尔逊提出硬软酸碱原则。2 一、酸碱质子理论 (一)...
Based on pH situ determination data,together with the results of variation in precipitation volume and precipitation partical size,the properties of lanthanum carbonate precipitated with sodium bicarbonate were investigated. 以pH值原位测定法为基础 ,结合沉淀体积变化、沉淀粒度及外观形貌分析结果 ,对NaHCO3沉...
