A blank solution is a solution containing little to no analyte of interest, [1] usually used to calibrate instruments such as a colorimeter. According to the EPA, the "primary purpose of blanks is to trace sources of artificially introduced contamination." [2] Different types of blanks are used to identify the source of contamination in the ...
CLEP tests are primarily multiple-choice exams (though some include fill-in or ordering questions, and one College Composition exam has an essay section) which are scored on a scale from 20 to 80. The majority of schools grant credit for a score of 50 or higher, but passing scores are determined by the individual schools and may vary.
A blank value in analytical chemistry is a measurement of a blank. The reading does not originate from a sample, but the matrix effects , reagents and other residues . These contribute to the sample value in the analytical measurement and therefore have to be subtracted.

Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
