在化学计算中,随着形势的发展,又涌现出了一批新型的计算题——信息给予型计算题.本文谈谈信息给予型的无机化学计算题的类型及解题思路,供参考.一、有关滴定度的计算题例1滴定度是指每毫升标准溶液相当于被测物质的克数,通常用T(M1/M2)表示.如:T(H2SO4/NaOH)=0.04g/m L表示每毫升标准硫酸溶液恰好中和0.04g NaOH.(1)若要使某标准盐酸对CaO的滴定度T
In the field of chemical calculation, a new batch of computational questions - information-giving computational problems emerge as the situation develops.This article talks about the types of information-giving inorganic chemistry computational questions and their solutions, for reference. First, the calculation of titration Example 1 titration refers to the standard solution per milliliter is equivalent to the measured substance in grams, usually T (M1 / M2) said, such as: T (H2SO4 / NaOH) = 0.04g / m L means that every milliliter of standard sulfuric acid solution is exactly neutralized with 0.04g NaOH.
