Why is distilled water boiled before it used in preparing sodium hydroxide titrant?
Distilling water removes impurities and gases that could interfere with the accuracy of the titration. Boiling the distilled water helps to remove any residual volatile compounds that may be present, ensuring that the water used is as pure as possible for accurate titration results.

How a buret and pipette are cleaned for use in titration?
To clean a buret and pipette for use in titration, you should first rinse them with distilled water to remove any residue. Next, wash them with a suitable cleaning solution, such as a diluted acid or base depending on the titrant used. Finally, rinse them with distilled water again and allow them to dry before use.
How much time should be allowed for the titrant to drain from the buret wall before a reading is made?
About 30 seconds is typically sufficient to allow the titrant to drain from the buret wall before taking a reading. This ensures that all the titrant has been delivered into the solution being titrated and minimizes errors in the titration results.
Why is it impossible to calculate the potential before titrant is added?
It is impossible to calculate the potential before titrant is added in a titration because you need to know the exact concentration of the analyte (substance being titrated) in order to accurately predict the potential. Without the presence of the titrant, which is needed to react with the analyte, the initial conditions are unknown, making it impossible to calculate the potential.
Would it matter if droplets of distilled water were left in the burette when it was filled with sodium hydroxide?
Yes, it would matter because any residual water in the burette could potentially dilute the sodium hydroxide solution, leading to inaccurate measurements or titration results. It is important to ensure the burette is completely dry before filling it with the sodium hydroxide solution to avoid any potential errors.
When approaching the endpoint for titration how can you tell that you are very close?
You can tell you are very close to the endpoint when the solution starts to change color more rapidly with each drop of titrant added, indicating that the titrant is reacting with the analyte more intensely. Another sign is when the pH of the solution changes more dramatically with each drop of titrant. It is important to add the titrant drop by drop at this stage to prevent overshooting the endpoint.
What effect would it have on the value of the concentration of sodium hydroxide if the conical flask contains some distilled water before the addition of potassium hydrogenphthalate?
the conentration will be increased.

How do you prepare 2M 100 ml sodium hydroxide solution?
To prepare a 2M solution of sodium hydroxide in 100 ml, you would need to dissolve 8 grams of sodium hydroxide (NaOH) pellets in approximately 80 ml of distilled water, and then add more distilled water to reach a total volume of 100 ml. Be cautious as the dissolution of NaOH in water is exothermic and can cause the solution to become hot, so allow it to cool before handling. Additionally, wear appropriate protective gear such as gloves and goggles when working with NaOH due to its corrosive nature.
How do you add distilled water in forklift battery?
Before charging it.
How long is distilled water good for before it expires?
Distilled water does not expire, as long as it is stored properly in a clean, sealed container.

Preparing for a dry fast?
Preparing for a dry fast involves taking certain steps before beginning your fast
How do you use distilled water?
Distilled water can be used in school labs to clean apparatus before switching between chemicals. Like measuring pH balance of different liquids you would use a pH indicator and when switching between the liquid you would clean the equipment with distilled water before dipping it into another solution
Should you add water to a battery before or after you charge it?
Add distilled water before for you charge it. Do not use tap water.
