Freezing point, hydrochloric acid concentration
Thread Content
When measuring the freezing point of antifreeze, the specified concentration for titration with hydrochloric acid standard solution is 0.1000 mol/L. What is the typical actual concentration of the hydrochloric acid standard titrant solution?
Just prepare it at a value as close as possible to 0.10M; after preparation, it can be calibrated using standard alkali. Since the concentration of hydrochloric acid available on the market is not fixed and accurate, it needs to be calibrated after preparation.
I cried – I wrote it wrong yesterday. It should be ‘measurement of reserve alkalinity’, how could I write it as ‘freezing point’ :Q. If the concentrations c1 and c2 on the screenshot are simply erased, isn’t it meaningless to not include sodium?
It seems I understand; I haven’t used it in the laboratory, and there are still some issues that I can’t grasp right away. If a standard version can be created, then it can be erased, right? Generally, it’s not possible to determine the significant figures of thinking, or if they are determined, the differences can be quite large, though they remain within a certain range.
