Theoretical purity formula
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. The actual yield is the amount that was actually made, which was 65.2 g of Zn (NO 3) 2.

WebbDistillation is one of the most important separation and purification methods for liquid substances. In the simplest case of distillation, a liquid is boiled by heating and the resulting vapor is cooled to condense as a distillate. Note: Only one phase, the vapor, is moving in this scenario.

WebbThe ratio can be calculated after correcting for turbidity (absorbance at 320nm). DNA purity (A 260 /A 280) = (A 260 reading – A 320 reading) ÷ (A 280 reading – A 320 reading) Strong absorbance around 230nm can indicate that organic compounds or chaotropic salts are present in the purified DNA. WebbpH of high-purity water The pH of water is defined as the negative logarithm of the hydrogen ion activity, which is often assimi-lated to the hydrogen ion concentration (Eq. [1], Table 1). While the pH of pure water is approximated to be 7.0 at 25 °C, the theoretical value is 6.998. Indeed, the dissociation of water and the ionic prod-uct for ...
