How do you clean pipette?
First remove all the solid particles from the burette using a scrubber. Then wash the burette with tap water followed by distilled water thoroughly (even the nozzle). Then wash the burette with the solution to be used in the burette.
Why is it important to fill the part below he tap of the burette?
It is important to fill below the tap of the burette to prevent air bubbles from entering the burette's delivery jet and affecting the accuracy of the volume measurements. Filling below the tap also ensures a consistent and accurate starting point for titrations.
How do tighten burette clamp on?
To tighten a burette clamp, adjust the screw on the clamp to apply pressure on the burette. Turn the screw clockwise to securely hold the burette in place. Make sure the burette is held firmly but not over-tightened to avoid damaging the glassware.
Why is it important to clamp the burette vertically?
To ensure that the actual volume of liquid delivered into the conical flask is read accurately
Why is a burette used in preparation of salt?
A burette is used in the preparation of a salt solution because it allows for precise measurement and dispensing of liquid volumes. This is important for accurately controlling the amount of solute (salt) being dissolved in the solvent to achieve the desired concentration.

How to clean a burette before fill it with hydrochloric acid?
To clean a burette before filling it with hydrochloric acid, rinse it thoroughly with distilled water to remove any impurities or residues. Follow this by rinsing with a small amount of the acid itself, disposing of it properly. Repeat this rinsing process until the burette is clean and ready for use.
Why ist necessary to rinse the clean burette before filling it with the unstandardised sodium hydroxide solution?
It is important to rinse the clean burette to remove any residual contaminants or impurities that could affect the accuracy of the titration results. Additionally, rinsing helps to ensure that the burette is properly conditioned for the new solution being used. This step helps to avoid any potential errors or inaccuracies in the titration process.

What is the proper technique for filling a burette tip to ensure accurate measurements in a laboratory setting?
To ensure accurate measurements when filling a burette tip in a laboratory setting, the proper technique involves slowly and carefully filling the burette tip with the liquid being measured, making sure there are no air bubbles present. This can be done by allowing the liquid to flow down the sides of the burette tip and tapping the burette gently to release any trapped air bubbles. It is important to stop filling the burette when the liquid level is at the zero mark on the burette scale to ensure precise measurements.
How do tighten burette clamp on?
To tighten a burette clamp, adjust the screw on the clamp to apply pressure on the burette. Turn the screw clockwise to securely hold the burette in place. Make sure the burette is held firmly but not over-tightened to avoid damaging the glassware.
How do you clean a burette with stopcock stuck in it?
To clean a burette with a stuck stopcock, try soaking the burette in warm water to loosen any residue or buildup. If the stopcock is still stuck, you can try applying a lubricant such as silicone grease around the stopcock and gently tapping it to help loosen it. If these methods do not work, consider seeking help from a professional or replacing the stopcock.
What instruments holds the burette?
A ring clamp is used to hold a burette.
Why burette used to measure acid?
A burette is used to measure acids or other liquids with high precision because it allows for precise volume measurements to be made. The graduations on the burette make it easy to accurately measure and dispense liquids in small increments, which is important when working with chemicals that need to be measured precisely, such as acids. Additionally, the stopcock valve at the bottom of the burette allows for controlled dispensing and titration.
What is Relative standard uncertainty in burette?
The smallest possible burette reading is 0.10 and the uncertainty of a burette's reading is half of its smallest value (0.05).
What is is the use of burette holder in chemistry lab?
A burette holder is used in a chemistry lab to securely hold a burette in place during titration experiments. It prevents the burette from tipping over or falling, ensuring accurate and precise measurements of the volume of liquid being dispensed.
What is the pupose of a burette?
A burette is used to very accurately measure liquid volumes.
