Quantitative Chemical Analysis

Title: Quantitative and Qualitative Analysis Purpose: The purpose of this experiment is to learn how to measure the amount of a substance that is present in a chemical compound. A metal carbonate will be analyzed to determine how much CO2 and moles of CO2 are lost. Another experiment will also look into how much water a hydrate loses and determine what type of hydrate it is. Paper chromatography will be used to determine the identity of chemical substances. Lastly, SEM/EDX will be used to d...

Quantitative Chemical Analysis

In the 18th century, the strength (actually the concentration) of _____ samples was determined by noting the amount of potassium carbonate, K₂CO₃, which had to be added, a little at a time, before bubbling ceased. The greater the weight of potassium carbonate added to reach the point where the bubbling ended, the more concentrated the _______. Vinegar, vinegar The test for vinegar concentration: acetic acid reacts with potassium carbonate according to the following equation: 2CH₃CO₂...
