A solvent blank is a sample that contains only the solvent used to dissolve the analyte, without any added substances. It serves as a control in analytical experiments to account for any background absorption or interference from the solvent itself. By measuring the solvent blank, researchers can subtract its effects from the results of samples containing the analyte, ensuring more accurate and reliable data. This practice is common in spectroscopic methods and other analytical techniques.
What else can I help you with?
In a solution the blank is dissolved by the blank?
In a solution the solute is dissolved by the solvent.
What would you use as a blank or reference if the solutions were made using 80 percent acetone in water as the solvent rather than pure water explain why?
Blanks are made using the same solvent used in your solutions. So, in this case, you would use 80 percent acetone in water. Blanks allow you to see what parts of your results are due to the solvent and what parts are due to the solute. If you used pure water as your blank, it would not show the effect of the 80 percent acetone in water on your results.
Why would it not be correct to blank the spectrophotometer with deionized water?
It would not be correct to blank the spectrophotometer with deionized water because deionized water does not contain any solutes that would contribute to the absorbance reading. The purpose of blanking the spectrophotometer is to zero the instrument by measuring the absorbance of a solution that only contains the solvent used in the sample. Using deionized water would not effectively remove any background interference from the sample, leading to inaccurate results. It is recommended to use a blank solution that closely matches the solvent and conditions of the sample being measured.
Why is Volume of HCl used for blank titration is more than volume of HCl used for oil titration?
The blank titration is used to determine the exact amount of acid needed to neutralize any impurities in the titration setup, such as the indicator and solvent. This additional volume of acid is accounted for in the blank titration and is subtracted from the volume of acid used in the titration with the oil sample.

What purpose does blank serve in a spectrophotometer?
In a spectrophotometer, a blank serves as a reference to account for any absorbance due to the solvent or other components in the sample that are not of interest. It typically contains all the components of the sample except the analyte, allowing for baseline correction. By measuring the absorbance of the blank, the instrument can subtract this value from the absorbance of the sample, ensuring that the results reflect only the absorbance due to the analyte of interest. This improves the accuracy and reliability of the measurements.
