Theoretical purity formula
WebbIntroduction. Recrystallization is a common method used to purify a sample. As the name implies a solid sample with suspect purity is dissolved into an appropriate solvent. The dissolution process is achieved heating or changing the pH. When heat is involved a solvent is chosen in which the solute has a low solubility at room temperature, but a ... Webb8 okt. 2014 · Unless based on a specific rationale, purity thresholds of the general format >“ X %” (e.g., “at least 99% pure” or “80% minimum purity”) commonly found in journal, pharmacopoeial, and regulatory guidelines as well as certificates of analysis must be considered as arbitrary values.

WebbA mass-mass calculation can be performed to determine the theoretical yield. We need the molar masses of Zn (65.39 g/mol) and Zn (NO 3) 2 (189.41 g/mol). In three steps, the mass-mass calculation is: Thus, the theoretical yield is 88.3 g of Zn (NO 3) 2.
