Minimum amount constant indicator titration why?
A minimum amount of constant indicator is used in titration to ensure that a small quantity of indicator does not influence the accuracy of the titration results. By using a constant amount, any impact on the endpoint is minimized, allowing for more precise determination of the equivalence point. This helps in obtaining accurate and reproducible results in the titration process.
How do you make phenolphthalein indicator for titration from powder?
To make phenolphthalein indicator solution from powder, dissolve a small amount of phenolphthalein powder (about 0.1g) in 100mL of ethanol or 95% ethanol and 5% water solution. Stir the mixture until the powder is completely dissolved. This will give you a pink indicator solution suitable for titrations.
Why are there blue precipitate at the end of redox titration?
The blue precipitate may indicate the presence of excess indicator in the solution. In redox titrations, the indicator changes color when the reaction reaches its endpoint. If too much indicator is added, it can form a colored precipitate due to its reaction with the titrant, which can obscure the endpoint of the titration. It is important to carefully control the amount of indicator to avoid this issue.
Why should a constant amount of indicator be used in a titration?
Indicators are weak acid. Too much will alter the titre
What is neutralization titrations?
Neutralization titrations are a type of volumetric analysis that involve determining the concentration of an unknown acid or base by reacting it with a standard solution of an acid or base of known concentration. The endpoint of a neutralization titration is typically marked by a color change using an indicator or by monitoring the pH of the solution. This method is commonly used to determine the amount of acid or base present in a solution.

The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
How do you use the word minimum in a sentence?
