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 the function of white tile in the acid-base titration experiment?
In an acid-base titration experiment, a white tile is used to provide a neutral background against which to observe color changes, making it easier to accurately detect the endpoint of the titration when using colored indicators. The white tile helps to enhance the visibility and contrast of color changes, allowing for more precise titration results.
What is the function of hhsnna in edta titration?
In EDTA titration, hhsnna (hydroxylamine hydrochloride) is used to reduce any interfering metal ions present in the sample to prevent their titration by the EDTA solution. This helps ensure that the titration results are accurate and only reflect the concentration of the target metal ion being measured.
How many tipes of titration?
There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.
What is over-titration?
Over-titration refers to the process of adding too much titrant during a titration, resulting in an endpoint that goes beyond the equivalence point. This can lead to inaccurate results as the excess titrant can skew the calculations.

What is the function of an indicator in titration?
An indicator in titration is used to signal the endpoint of the reaction between the analyte and titrant. It changes color at a specific pH or when the stoichiometric ratio of the reactants is reached, providing a visual cue that the titration is complete. This helps in accurately determining the equivalence point and calculating the concentration of the analyte.
What is a function of an indicator in a titration?
The function of an indicator in a titration is to signal the endpoint of the reaction between the titrant and analyte by changing color or another physical property. This color change helps the experimenter determine when the reaction is complete, allowing them to calculate the unknown concentration of the analyte.
What is the function of potassium iodide in iodometric titration?
Potassium iodide is used in iodometric titration as a source of iodide ions. It reacts with iodine to form triiodide ions, which are then titrated with a standard solution of thiosulfate to determine the concentration of the oxidizing agent.
What is the scout titration?
The scout titration is a preliminary titration carried out to estimate the approximate endpoint in a titration experiment before performing the actual titration. It helps in determining the approximate volume of titrant required for the main titration to avoid overshooting the endpoint.
What is the difference between iodometric titration and iodimetric titration?
Iodometric titration involves the titration of iodine with a reducing agent, while iodimetric titration involves the titration of iodide with an oxidizing agent. In iodometric titration, iodine is detected by a starch indicator to determine the end point, while in iodimetric titration, iodide ion concentration is determined by titration with a standard solution of an oxidizing agent.
What is the function of phenolphthalein in titration?
Phenolphthalein is a pH indicator commonly used in acid-base titrations. It changes color in a specific pH range (around pH 8.2 to 10), allowing the endpoint of the titration to be visually determined. This makes it easier to accurately measure the amount of titrant required to reach the equivalence point.
What is double titration?
Double titration is a titration method used to determine the concentration of a solution by performing two successive titrations. In the first titration, a known concentration of a standard solution is used to titrate the unknown solution. In the second titration, a different standard solution is titrated with the excess volume from the first titration to determine its concentration.
