This is the first assignment for Unit 14 BTEC Applied Science. This is one of my most worked on assignments and I can fully ensure you that covers all the key aspects of the specification in order to achieve a distinction grade. please use it as a guide on how and what to write and not copy and paste because that will count as plagiarism. A full bibliography is attached at the end. Have fun and good luck ;)

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...
