What is a blank solution?
http://www.speciation.net/Public/Objects/Glossary/index.html? we_objectID=299&rb_select_l=B&rb_search=&PHPSESSID=363d Glossary ---- blank solution 1. a solution that does not contain a detectable amount of the analyte of interest. The blank solution is typically used for calibration purposes. Depending on its purpose the following blank solutions can be defined: Calibration blank (the solution used for creating the zero concentration point of the calibration graph; this solution contains only the diluent used for making the standard solution) 2. Reagent blank (a blank solution that contains the reagents used to dissolve the samples such as acids used for digestion; the reading for this solution is typically substracted from sample readings) 3. Method blank (a blank solution that has been handled similar to a sample, and to which the same reagents have been added, that had contact to the same type of vessels and that was treated by a similar procedure. This solution than is handled to monitor any type of contamination taking place with the method used. The correct treatment of the analytical result for the blank solution does have a significant effect on the correctness of analytical results, especially for samples having analyte concentrations close to the limit of quantitation. Especially the measurement of the reagent and method blank must be well differentiated from the baseline correction.
In a solution the blank is dissolved by the blank?
In a solution the solute is dissolved by the solvent.
Are mixtures and solutions similar?
Mixtures and Solutions are the same because they both use each other to do what they do. Solutions use Mixtures because you have to mix things together that are solutions to get solutions. Although mixtures don't need solutions to do anything solutions are very helpful.
What Are alloys solutions or suspensions?

Can a metal dissolve into a liquid?
Yes. Metals can be dissolved into liquid solutions. Several metals can be dissolved in acidic media such as HNO3 to prepare acidic solutions of these metals.
What piece of glassware is used to prepare very accurate concentrations of chemical solutions?
