What is the purpose of Volhard titration?
The purpose of Volhard titration is to determine the concentration of halide ions (such as chloride, bromide, or iodide) in a solution by titrating with a standardized silver nitrate solution. The endpoint of the titration is indicated by the formation of a colored precipitate of silver halide.
How do you measure ammonia in Cyanide waste solution?
Ammonia in cyanide waste solution can be measured using techniques such as colorimetry, ion-selective electrodes, or spectrophotometry. These methods involve detecting the ammonia concentration by forming a colored complex with a reagent or measuring the change in absorbance at specific wavelengths. It is important to ensure proper sample preparation and calibration of the instrument for accurate results.
True or false As the concentration of a colored solution increases the absorbance value decreases?
Absorbance rises with concentration because there is more material for a given frequency of light to be absorbed in. Your statement is false.
What is the aim of a thermometric titration?
The aim of a thermometric titration is to measure the heat change that occurs during a titration reaction. This can be used to determine the endpoint of the titration, as it corresponds to the point of maximum or minimum heat change. Thermometric titrations are useful for studying reactions that do not produce a visible change in color or involve weakly-colored solutions.
Why is formaldehyde or formalin used in formol titration procedure?
Formaldehyde or formalin is used in formol titration procedure as a titrant because it reacts with the substances being titrated and forms a colored complex that can be easily detected. This complex formation allows for a precise determination of the concentration of the analyte in the sample being tested.

Can colorimetry be used to test concentration of citric acid?
It can be if you can convert the citric acid to a chromophore, i.e., something that is colored. Otherwise, you cannot.
What are the instruments used for Colorimetry?
Colorimetry primarily utilizes colorimeters and spectrophotometers as its main instruments. A colorimeter measures the concentration of colored compounds in solution by assessing their absorbance at specific wavelengths. Spectrophotometers, on the other hand, provide more detailed analysis across a broader spectrum of wavelengths, allowing for more precise measurements and the study of various substances. Both instruments are essential for applications in chemistry, biology, and environmental science.

How do you find the concentration?
Equation to find concentration"Titration"Concentration = Number of moles x 1000 ÷ Volume (cm3)"Molarity"Concentration [Molar] = Number of moles ÷ Volume (cm3)

How does a Colorimeter work in Colorimetry?
A colorimeter measures the absorbance or transmittance of light across a certain range of visible wavelengths to determine the concentration of a specific colored compound in a solution. It compares the intensity of light before and after passing through the sample to quantify the color intensity. The data collected is typically used to generate a calibration curve relating color intensity to concentration.
What is the function of NH4CNS in estimation of the amount of copper present in a supplied solution by iodometric method?
NH4CNS (ammonium thiocyanate) is used as an indicator in the estimation of copper by the iodometric method. It forms a red-colored complex with the copper ions, allowing for visual detection of the end-point during the titration process. The indicator changes color when all the copper ions have reacted with the iodine, indicating the endpoint of the titration.
What is complexometry?
A chemical technique using the formation of a colored complex to indicate the end of a titration.
What is compleximetric titiration?
Complexometric titration is also known as chelatometry. It is a form of volumetric analysis in which the formation of a colored complex is used to indicate a titration's end point.
