Why Erlenmeyer flask does not have to be dry and why water may be added?
The Erlenmeyer flask does not have to be dry because it is commonly used for mixing solutions or conducting reactions where water or other solvents are needed. Water may be added to the Erlenmeyer flask to dilute a solution, adjust its concentration, or facilitate a reaction. It also helps ensure better mixing and dissolving of substances.
Why is is not necessary to dry an Erlenmeyer flask before transferring the solid KHP to Na-OH?
The Erlenmeyer flask is typically dry enough for the transfer since the small remnants of water will not significantly affect the reaction between KHP and NaOH. Additionally, any remaining water will not be present in large enough quantities to cause a significant difference in the calculated concentration of the NaOH solution.
How do you write a hypothesis about dry ice experiment?
A hypothesis for an experiment involving dry ice could be: "I predict that placing dry ice in warm water will cause it to rapidly sublimate, creating a cloud of carbon dioxide gas due to the temperature difference between the dry ice and water." This hypothesis clearly states the expected outcome of the experiment and the reason behind it.
Is it necessary to rinse the conical flask with some standard solution of oxalic acid before use?
I believe it is necessary to rinse the conical flask with oxalic acid before use, unless you are sure that the conical flask is really clean and dry before use. However to prevent having any types of unwanted chemical reaction when you pour the oxalic acid in the flask, it is best to rinse it with oxalic acid before use, so that there will not be errors like e.g. there is no pinkish color formed in the solution when you add the color indicator in the oxalic acid when doing titration.
What is an bibliography in dry ice bubble?
A bibliography in dry ice bubble experiment would list all the sources (books, articles, websites, etc.) that you consulted or referenced when conducting the experiment or writing about it. It helps to give credit to the original sources of information and allows others to further explore the topic.

How do clean a beaker?
Acid washing it should do. I assume you are in a lab...in which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.
What will happen if a wet Erlenmeyer flask is used to transfer acid solution from the volumetric pipette?
It will slip out of your hands, fall to the floor, break, and cause the principal to evacuate your whole school until the fire department comes to neutralize the spill. Keep your flasks dry, please.
Is it necessary to dry clean the conical flask before use?
yes
Why should the neck of a volumetric flask be kept dry?
Keeping the neck of a volumetric flask dry ensures that any liquid adhering to the neck does not affect the accuracy of the volume measurement. This prevents contamination and evaporation of the liquid, ensuring that the correct volume is measured each time the flask is used.
Experiments of sublimation using some chemicals?
A simple experiment to show/prove sublimation is by using pottasium permangenate(solid) . All you need is a conical flask with a fairly long neck. Drop the pottasium permangenate into the conical flask and seal the mouth of the flask. Hold the flask to a flame from a bunsen burner. The heat from the burner should make the pottasium permangenate sublime into it's gaseous form producing a purple coloured gas. Then once it reaches the neck of the flask it will lose it's heat and cool down to form pottasium permangenate crystals. And there you have it! A simple experiment of sublimation.....
What is the purpose of your experiment ON DRY ICE?
nothing
Why the temperature in a flask tha contains dry peas doesn't change at the room temperature?
The temperature in the flask remains constant because the peas act as insulation, limiting heat transfer between the inside and outside of the flask. This insulation effect prevents the temperature from changing easily.

How to wash a flask properly?
To wash a flask properly, first rinse it with warm water. Then, use a bottle brush and mild soap to scrub the inside. Rinse thoroughly with clean water and let it air dry upside down. Avoid using harsh chemicals or abrasive materials that could damage the flask.
