Once you have measured out your sample and transferred it to your flask, the absolute amount (moles) of sample is fixed. Adding water to the flask will change the concentration in the flask, titrating also adds volume to the flask as well as reacting with the sample. However, the number of molecules of sample you put into the flask will not change by simply diluting it with water.

What is the titration flask?
A titration flask is a glass vessel with a narrow neck and a flat bottom used in titration experiments. It typically has volume markings for precise measurement of liquids added or titrated during the experiment.
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.
What is a good practice to follow in a titration?
A good practice in titration is to perform a rough titration to estimate the volume of titrant needed, followed by careful and slow addition of titrant near the end point to ensure accuracy. It is important to swirl the solution gently during titration to ensure proper mixing. Finally, make sure to record the exact volume of titrant added at the end point.
What is the name of the process when you combine an acid with a base?
The process of combining an acid with a base is called neutralization. This reaction produces water and a salt.
How do you prepare 0.1 N solution HCL from 1N?
To prepare a 0.1 N solution of HCl from a 1 N solution, you would need to dilute the 1 N solution with 9 parts of water. To do this, add 1 part of the 1 N HCl solution to 9 parts of water (for example, 10 mL of the 1 N solution to 90 mL water) to get a final 0.1 N HCl solution.
