In the water to wine chemistry demonstration how come the red liquid is able to turn into a clear liquid by blowing on it with a straw or pipette?
Because the oxygen and carbon dioxide in your breath dissolve into the solution and react with the molecules which absorb light and change them into a form which no longer can absorb light. I think this arises from the oxidation of the molecules, but it could also result from the change in pH of the water due to the dissolved carbon dioxide changing to carbonic acid.

What can measure ml of liquid material in chemistry?
We can use a graduated pipette, a small cyllinder, a burette.
What piece of apparatus can measure exactly cm of a liquid how the answer is pipette?
pipette
What do you call the instrument that holds the pipette?
The instrument that holds the pipette is called a pipette bulb or a pipette filler. It is used to create suction for drawing liquid into the pipette and controlling its release.
When can a mouth used to suck liquid into the pipette?
The mouth should never be used to suck liquid into a pipette. This is because it can be dangerous due to potential exposure to harmful chemicals, contamination of the sample, and inaccurate measurements. It is recommended to use a bulb or pipette aid to safely draw liquid into the pipette.
What is pipette and how is it used in Hindi?
A pipette or chemical dropper is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser.इस वैक्यूम को रिहा करने खींचना और तरल बांटना।
Why it not suitable to empty the last liquid drop of a pipette by blowing or any other method?
Because the calibration of the pipette was made ignoring this drop.
What is a pipette bulb use for in chemistry?
A pipette bulb allow a liquid to be sucked up into the pipette, so avoiding having to use your mouth to suck the liquid up. Apart from avoiding often toxic liquids getting into your mouth, it also avoids contamination of the liquid.

We can use a graduated pipette, a small cyllinder, a burette.
How can a liquid be safely drawn into a pipette?
To safely draw a liquid into a pipette, first ensure the pipette tip is submerged in the liquid. Then, slowly and steadily press the plunger to create a vacuum, which will draw the liquid into the pipette. Be careful not to overfill the pipette to prevent spills or inaccuracies in measurements.

pipette
How do you properly use a serological pipette for accurate and precise liquid measurements?
To properly use a serological pipette for accurate and precise liquid measurements, first ensure the pipette is clean and calibrated. Then, draw the liquid into the pipette slowly and steadily, making sure the meniscus is at the desired volume mark. To dispense the liquid, touch the tip of the pipette to the receiving vessel and release the liquid slowly. Avoid introducing air bubbles and always handle the pipette carefully to maintain accuracy.

What is the function of pipette?
A pipette is a laboratory tool used to accurately measure and transfer small volumes of liquid. It is commonly used in biology, chemistry, and other scientific disciplines for tasks such as mixing reagents, preparing samples, and conducting experiments.

How can I efficiently deliver a precise amount of liquid using a pipette?
To efficiently deliver a precise amount of liquid using a pipette, first ensure the pipette is calibrated and set to the desired volume. Then, immerse the tip of the pipette into the liquid and slowly draw up the liquid by gently pressing and releasing the plunger. To dispense the liquid, carefully release the plunger to deliver the precise amount. Be sure to hold the pipette vertically to prevent any spills or inaccuracies.
How do you properly use a pasteur pipette for accurate and precise liquid transfer in the laboratory?
To properly use a pasteur pipette for accurate and precise liquid transfer in the laboratory, first, ensure the pipette is clean and dry. Next, draw the liquid into the pipette by gently squeezing the bulb and placing the tip into the liquid. Release the bulb slowly to draw in the desired amount of liquid. To dispense the liquid, hold the pipette at a slight angle and gently press the bulb to release the liquid drop by drop. Be careful not to introduce air bubbles, and always handle the pipette with care to avoid spills or contamination.
