What is electrometric titration?
Electrometric titration is a method of determining the concentration of a specific ion in a solution by measuring changes in electrical potential. It involves using an electrode pair to detect the equivalence point of a chemical reaction based on changes in voltage. This technique is commonly used in analytical chemistry to measure acidic or basic components in a sample.
Why use double indicator in titration?
Using a double indicator in titration can provide more accurate results because different indicators change color at different pH levels, allowing for a more precise endpoint determination. This method helps to identify a narrower range where the titration is most effective, resulting in a more accurate determination of the equivalence point.
What is electrometric method?
electrometry is a powerful technique of analytical chemistry , which is based on the electrical properties and involves measurement of current ,voltage, or resistance in relation to the concentration of a certain species in solution . Apart from electrogrvimetry where the material deposited on one of the electrodes is weighed after the electrolysis is carried out .
What is the standard reference method for protein determination?
The standard reference method for protein determination is the Kjeldahl method. This method involves digesting the protein sample with concentrated sulfuric acid and then measuring the amount of nitrogen present, which is used to calculate the protein content.
Why mohr method is better than volhard method?
The Mohr method is typically preferred over the Volhard method for chloride titrations because it does not require a silver nitrate standard solution, making it more cost-effective and simpler to execute. Additionally, the Mohr method is more precise as it allows for a direct endpoint determination based on the formation of a specific silver chloride precipitate.

What is Nelson method?
its a method for determination of reducing sugars
Why is determination of density by the slope method generally more accurate than a from individual data points?
The determination of density by the slope method is generally more accurate because it involves finding the slope of a linear relationship between mass and volume, which reduces the effect of random errors in individual data points. This method is based on multiple data points and takes into account the overall trend in the data, leading to a more precise calculation of density.
How you find out how much salt there in a sample of water?
1. Using an instrument called salinometer. 2. A more accurate method: chemical determination of sodium and chlorine.

What is Meyer's oscillating disc method?
Meyer's oscillating disc method is a technique used to determine the molecular weight of a polymer by measuring the change in weight of a solution containing the polymer as it oscillates at a specific frequency. This method allows for accurate determination of molecular weight and can be used to study the size and structure of macromolecules.
Why the pycnometer method more accurate than the hydrometer method?
The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.
What is the standard reference method for protein determination?
The standard reference method for protein determination is the Kjeldahl method. This method involves digesting the protein sample with concentrated sulfuric acid and then measuring the amount of nitrogen present, which is used to calculate the protein content.
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.
