Burette to addsmall, measured volumes of one reactant to the other reactant in the conical flask (考点小提示:请特别留意Pipette和Burette的拼写,考试中同学们可能被要求标注实验仪器的名称,有拼写准确度分值哦!) 实验步骤 以以下实验为例: 氯化氢 + 氢...
This application note describes the thermometric titer determination of sodium hydroxide NaOH using hydrochloric acid HCl as primary standard. The neutralization of a strong acid with a strong base is an exothermic chemical reaction that can be monitored by measuring its temperature changes. Thermometric ...

General form of a titration curve It's worth taking some time to thoroughly familiarize yourself with the general form of a titration curve such as the one shown below, in which a weak acid HA is titrated with a strong base, typically sodium hydroxide. ...
knowledge of the identity of the titrant and analyte. A common experiment in high-school and college chemistry labs is the titration of acetic acid (CH?COOH, the analyte) in a sample of vinegar with sodium hydroxide (NaOH, the titrant) (See References 2). This is a common acid-base ...
In the neutralization of hydrochloric acid by sodium hydroxide, the mole ratio of acid to base is 1:1. One mole of HCl would be fully neutralized by one mole of NaOH. If instead the hydrochloric acid was reacted with barium hydroxide, the mole ratio would be 2:1. ...
What is the concentration of 0.15 mL HCl if 20.7 mL of 0.5 M NaOH is required to neutralize it? To work out an unknown concentration of 0.15 mL HCl:Use the 1:1 ratio formula because one mole of HCl reacts with one mole of NaOH – HCl...
