Why does it not matter how much water you add when dissolving the acid or when carrying the titration?
The titration equivalence point occurs when the acid present in the sample has been exactly neutralized by the volume of base added. Additional water added to the reaction vessel has no effect on the volume of base added.
Why does the volume of water in a titration not matter?
The volume of water in a titration does not matter because it does not participate in the chemical reaction taking place. The key factor in a titration is the concentration and volume of the analyte and titrant being used. The volume of water is often used to dilute the solutions to a manageable volume for titration.
Why methanol is used in KF titration?
Methanol is used in Karl Fischer (KF) titration as a solvent and reaction medium for dissolving the sample being tested. It helps to facilitate the reaction between iodine and water in the titration process by making the water in the sample readily available for titration. Additionally, methanol helps to prevent side reactions that may interfere with the accurate determination of water content in the sample.
How do you prepare methyl red for titration?
To prepare methyl red for titration, first make a stock solution by dissolving the dye in a suitable solvent such as water or alcohol. Then, carefully add the desired amount of the stock solution to your titration flask based on the concentration needed for your specific experiment. Finally, ensure proper mixing before using the solution for titration.
Why does it not matter if conical flask you wet with water during titration?
Wetting the conical flask with water during titration helps to ensure thorough mixing and prevents solution splashing or clumping on the sides of the flask. This can help in obtaining accurate and consistent titration results.

What is a 5 example of solubility?
Sugar dissolving in water. Salt dissolving in water. Oil not dissolving in water. Ethanol dissolving in water. Carbon dioxide dissolving in soda.
Is dissolving in water a chemical change?
Dissolving in water is a physical change.
What is the process called when water passes through rock or soil dissolving and removing substances?
This process is called leaching. Water passing through rock or soil can dissolve minerals and other substances, carrying them away with the moving water.
Why is salt in water a physical change?
Dissolving salt into water is a physical change because no chemical reaction takes place, while the state of matter of the salt changes.
How do you explain dissolving?
Dissolving is a process where a solute (such as sugar or salt) breaks down into individual particles and mixes evenly with a solvent (such as water) to form a solution. This occurs at a molecular level as the solvent molecules surround and separate the solute particles. Dissolving is a physical change that can be reversed by evaporating the solvent, leaving behind the solute.
What is the liquid used for dissolving?
Dissolving what?Water is a pretty common solvent.
Is dissolving sodium chloride a physical change?
Yes, dissolving sodium chloride in water is considered a physical change. This is because only the state of matter changes (solid to aqueous solution), and no new substance is formed.
