A blank solution is used in the Mohs hardness test to serve as a point of reference for comparison. By observing how the blank solution interacts with the unknown mineral sample, the tester can accurately assess the hardness of the sample by determining if it scratches, is scratched by, or is comparable in hardness to the blank solution.

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.


What is the purpose of using the blank solution?

The blank solution is used to be compared with a solution containing a component to be determined; the blank solution is supposed to be uncontaminated by this substance. The blank solution is important for the calibration of instruments.


What solution blank to measure anthocyanin?

It can be measured by UV- spectrophotometer. The pH differential method has been used to determine the anthocyanin content


Why were a reference solution and a blank used in each test?

A reference solution was used in order to see what reaction happens between a test reagent and a solution with a high value of the ions being tested. A blank was used to show that there is no reaction when the ion being tested for is not present in the solution.

Why indicator blank is used in mohr method?

An indicator blank is used in the Mohr method to account for any color changes that may occur due to impurities in the indicator itself. By measuring the blank, you can subtract this error from the titration result, ensuring accurate determination of the analyte concentration.
