What are the similarities and differences between DNA and RNA? Describe the use of acyl anion equivalents in synthesis. Use appropriate chemical structures to illustrate the answer. Separating biomolecules is key in studying them. Draw the structure of an amino acid and a fatty acid and label the...

The type of sorbent you choose for the solid phase, and solvents for the mobile phase, depend largely on the nature of your sample or analyte of interest. The primary characteristics of polarity and charge—whether the analyte is polar, nonpolar, or a cation or anion—will help you determine...
a tag—when researchers can look for properties to help determine the most efficacious media and strategy. The protein’s isoelectric point (pl) compared with the pH of the buffer, for example, can help decide whether an anion-exchange or a cation-exchange column might be helpful. Similarly,...
[11,12,14,40,41], where the obvious differences in the diffusion parameters derived in the TD experiments could only be attributed to test conditions such as the cation or anion, the oxi-reducing conditions, the ionic strength, the pH in the aqueous phase, and differences in the type of ...
Figure 01: Large cation and anion exchangers that we can use for Demineralization There are several parameters that we use to measure the water quality (if water is pure or not) such as the pH, conductivity,BOD, COD, etc. Usually, we produce purified water from either drinking water or gr...
The complete ionic equation is a chemical equation that explains the chemical reaction, clearly indicating the ionic species present in a solution. An ionic species is either ananion(negatively charged species) or a cation (positively charged species). In contrast, a complete molecular equation gives...
When considering the nomenclature of ionic compounds, we need to give the name of the cation first, followed by the name of the anion. There are different ways of naming these compounds. For instance, we can name the cation by indicating the oxidation state using Roman numbers, i.e. iron...
