In the adsorption of acetic acid by charcoal why are the flasks stopperd?
The flasks are stoppered during the adsorption of acetic acid by charcoal to prevent the loss of acetic acid vapors into the atmosphere. This allows for better control of the experiment, ensuring that the adsorption process occurs within the enclosed flask and the concentration of acetic acid is maintained.
What reacts readily with acids such as hydrochloric?
Small amounts of chlorine gas can be made in the laboratory by putting concentrated hydrochloric acid in a flask with a side arm and rubber tubing attached. Manganese dioxide is then added and the flask stoppered. The reaction is not greatly exothermic. As chlorine is denser than air, it can be collected by placing the tube inside a flask where it will displace the air. Once full, the collecting flask can be stoppered.
How do you use the word flask in a sentence?
I always carry a flask filled with water when I go hiking to stay hydrated.
What is another word for triangular flask?

Should you use a flask which is a good conductor of heat or poor conductor to keep the tea inside the flask warm?
You should use a flask that is a good insulator or poor conductor of heat to keep the tea warm. This will prevent heat from escaping the flask and help maintain the temperature of the tea for a longer period of time.
Why a conical flask containing a hot solution is not tightly stoppered to prevent solvent during cooling?
Because... if it's tightly sealed - during cooling the volume of the solvent will decrease - making the pressure inside lower than outside he flask. This could be enough for the glass to shatter - spilling the contents.
What is the 8 letter word beginning with d for stoppered bottle?
The word is decanter. It is a stoppered glass container into which wine is decanted.
Why should we use plastic-stoppered bottles for bases?

How many decimal places should be used to record the volume of a 250ml volumetric flask?
The answer depends on the graduation on the flask.

What safety rule should you do before getting a hot flask?
Before getting a hot flask, ensure to check the temperature of the flask by touching it lightly to avoid burning yourself. Additionally, always make sure that the flask is stable and won't tip over, potentially causing spills or burns.
