Considering osmosis- If a hypertonic solution causes water molecules to leave a liver, and a hypotonic solution causes water molecules to enter a liver, an isotonic solution water molecules would neither enter, nor leave a cell. I hope this helped :)
A solution can be separated by evaporating the water which will leave the solutes on its own and the solvent as a gas.
If you know that you are out of contact lens solution, immediately go out and buy some. You can not put anything in the till except for contact lens solution. I usually shake my bottle and listen to how much I have in the bottle
My silver necklace tarnishes quickly after contact with my Betadine shampoo. To fix it, I leave it in a cup with warm water with baking powder dissolved in it. Also leave in the solution a piece of aluminium foil. My necklace comes out an hour later looking like new.
When phenolphthalein comes into contact with a basic solution, it turns pink-ish, or as you see it, fuchsia. When sodium and water react, the result is NaOH. Given that the presence of OH ions is, in essence, what makes a solution basic, it goes without saying that a solution of the three would be pink/fuchsia.
It is better to keep you eye contact in water because it isn't good for your eye to have it in for very long. (more than waking hours)
When elements and compounds dissolved in water leave a solution, it is called precipitation. Precipitation occurs when the solubility limit of the substance in the solution is exceeded, causing the excess to form a solid that settles out. This process can be used to purify substances or separate components in a mixture.
You can pour the solution into a tray and set in in sun light and leave it for several minutes.
you could use water, however it doesnt work as well.
No. Salt and water becomes a solution, not a new compound.
Contact.
Put them in clean water, but be sure to soak them in solution before putting them in your eyes again. This is important because the solution kills germs but water does not. It is very important to have contact solution always. If you run out and too broke to buy another bottle, then go to your optometrist. He/she will be glad to give you a trial bottle.
