How does the osmosis rate change?
Osmosis rate increase when the gradient increase. That means if you have two flask, first one has salt at a concentration of 30 %, and the second one has salt at 10 %. When you connect the two flasks together, water will move from the area of high water (low salt concentration) to the area of low water (high salt concentration), from the second flask to the first. And, if you increased the difference in gradient (first flask 60 % salt and the second 10 %) so the difference will increase and the osmosis rate will increase too.
Is ability of water to vaporize a chemical or physical property?
It is a physical property.
Why is the conical flask only rinsed with distilled water in the titration procedure?
Yes. By adding water to rinse, you will be changing the concentration of the thing you are titrating, and so your calculation will be off. If you have material on the walls of the flask, just gently stir the flask and let the solution in the flask wash anything off the walls. I do not believe this is true. Once you add an amount of reactant into your flask adding more water will not change the number of moles of reactant that are present in the flask. The titrant will react in the mole ratio for that particular reaction so water doesn't play a role. You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.
Why was it necessary to match the water levels inside and outside the cooled flask before removing it from the water bath?
So to equalize the pressure inside the flask with that of the atmosphere.
Why wouldn't it be sensible to put an ice cube in a vacuum flask?
When water freezes becoming ice it expands. In a vacuum flask as ice melts it will contract. This will cause the flask to crack.
If a water ethanol mixture is distilled which will be collected first?
The ethanol will be distilled first and the water stays in the flask
Will the water in a car battery vaporize if overcharged?
Yes the electrolyte will vaporize if the battery is overcharged.
What is a sentence using the word vaporize?
He left the water outside in the sun, so it will soon vaporize
Why is it acceptable to add water to the titration flask?
Once you have measured out your sample and transferred it to your flask, the absolute amount (moles) of sample is fixed. Adding water to the flask will change the concentration in the flask, titrating also adds volume to the flask as well as reacting with the sample. However, the number of molecules of sample you put into the flask will not change by simply diluting it with water.
Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.
What do you call the object that keeps water hot for hours?
Thermos flask or vacuum flask.
Must a flask be a good conductor of heat?
so as to keep the flask hot hereby keeping the hot water inside the flask hot.
What change in the water level occurs when you hold Erlenmeyer flask over a candle in a pan of water?
When you put a flask over the candle in a pan of water, the water in the pan starts to slowly rise inside the flask, and as the water slowly starts to rise, the candle slowly burns out.
What is the adjective for vapour?
Vapourous is the adjective related to the word vapour. Adjectives describing vapour include water, mysterious, and eerie.
What are two factors that could slow the transfer of water from the reservoir flask to the receiving flask?
swelling in the pumps.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
