What is the difference between voltametry and amperometry?
An amperometry measures a current at a fixed applied potential, that is at one point on the current-voltage curve. But in voltammetry it records a number of points on, or a chosen region of the current voltage profile. Thus an amperometry is a fixed-potential voltammetry. submitted by; Jas Raj Subba PSU
What chemical test is used to measure citric acid content in drinks?
The titration method, specifically using sodium hydroxide (NaOH), is commonly used to measure citric acid content in drinks. The citric acid reacts with the sodium hydroxide to form a salt and water. The level of citric acid can be calculated based on the amount of sodium hydroxide used in the reaction.
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 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 operational difference between polarography and amperometer?
Polarography is a type of voltammetry that measures current at varying potentials to analyze electroactive species, while amperometry measures current at a constant potential to study concentration changes over time. In polarography, the potential is scanned to generate a voltammogram, while amperometry uses a fixed potential to monitor changes in current.

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 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.
What equipment is used for titration in industry?
titration sensors
What is pilot titration?
Pilot titration is a preliminary test to determine the approximate endpoint of a titration process before conducting the actual titration. It helps in estimating the volume of titrant needed for the main titration, ensuring more accurate and efficient results. The data obtained from a pilot titration can help in planning and executing the main titration with greater precision.
What is Back titration?
A back titration is a form of titraiton in which an excess of standard reagent is added and then the reverse of the titration is carried out.
