This article is interesting, and brought back memories for me of my high school chemistry class. I was not very good in this class, and dropped and broke my share of lab beakers! Categories Science Engineering Astronomy Chemistry Biology ...
When the alkalinity level in water is higher than the natural alkalinity level in the soil, water may be unsuitable for irrigation. The pH Level in Drinking Water The pH level of the water is measured on a scale of 0 to 14. If the measurement is below 7, the water is acidic. ...
Titration is the process in which onesolutionis added to another solution such that it reacts under conditions in which the addedvolumemay be accurately measured. It is used in quantitative analytical chemistry to determine an unknown concentration of an identified analyte. Titrations are most commonl...
What gases can be a threat when they are part of the air inside your home? How would you determine if they are present? At what level do they present a threat? Air Pollution: Air pollution is pollution that is mainl...
The first thing to understand about the fact is that it is not found in nature. The portable, validated knowledge-object that one can simply invoke as a given truth was a creation of the seventeenth century: Before, we had neither the underlying concept nor a word for it. Describing this...
How Is Titration Carried Out? The analyte is measured and filled in a beaker. A few drops of an acid base indicator, such as methyl orange or phenolphthalein, is added to the analyte. Phenolphthalein remains colorless in acid, but turns pink in the presence of a base. Similarly, methyl or...
In potentiometric titration, the concentration-dependent potential (mV) of a solution is measured against a reference potential. In practice, potentiometric titration bears similarity to a redox reaction. However, potential is measured across the analyte — typically an electrolyte solution — using refer...
Bars acceptable for delivery range in size from as much as 1,000 troy ounces for some silver bars to 100 troy ounces. Some bars are measured in kilograms and taels, a Chinese unit of measure for precious metals. Traders who take direct ownership of precious metals, instead of receiving ware...
