it must be dissove in 1000cm3 of water or 1dm3
An unsaturated solution has excess solvent and can still dissolve more solute.A saturated solution cannot dissolve any more solute, it will simply stay separate.
The solubility is the total quantity of a solute dissolved in a given volume of solvent (100 mL or 1 L) at a given temperature and pressure.
Solutions have different ranges of temperature in relation to saturation...generally, the hotter the temperature the more of the substance can be dissolved...I thought saturated meant that it was holding as much as it could already....Sinerly Rar349
Substances can be tasted only when they are in water solutions, and if a substance is not in solution when taken into the mouth, it must be dissolved in saliva before it can be detected by the taste buds
Well, It will dissolve faster before the ice is added, but this wont help, there is more to it. For an explanation keep reading. If you dont want to read the explanation, than technically the sugar will dissovle faster before ice. So.... The hotter the substance, the faster the dissolving will happen. This is because the higher heat = higher kinetic energy, which basically means the particles are moving faster. When the particles move faster, collisions between particles happen more often, breaking up the solute (sugar) faster. Also, agitating the solution (stirring) will speed up the dissolving. This is because when the sugar is dissolving, the dissolved sugar surrounds the undissolved sugar. When you stir the solution, the dissolved sugar moves so that the lemonade or tea can touch the undissolved sugar and dissolve it. However, if you have completely saturated the solution before you add the ice (meaning the maximum amount of sugar is dissolved), when you add the ice, some of the sugar will begin to crystallize again. There will be less dissolved sugar in the tea, and more sugar crystals on the bottom. This is due to the solubility changing when the temperature is lowered. You could supersaturate the solution by leaving it undisturbed as you slowly cool it, keeping the sugar dissolved, but when you pick it up to drink it, the crystals will form on the bottom again. So there is no point to this. So, if you want sugar to dissolve faster, add it before the ice. However, when the ice is added, sugar crystals will then form on the bottom. I would recommend adding the sugar after the ice and stirring until only a little sugar shows up on the bottom. If you cant see the bottom, then add however much you want, but know that the lower the temperature, the less ice can be dissolved. There is much more to this, but just drink your lemonade/tea.
Saturated means that the solvent in the solution has dissolved as much solute as it can before solute no longer dissolves and would just fall to the bottom (of a breaker, or whatever you're holding the solution in.)

Concentrated brine is water with a large quantity of salt dissolved in it. Liquids like water have a limit to how much can be dissolved in them before they become 'saturated' - nothing more will dissolve because it can't 'fit'. This limit is proportional to temperature, so heating the brine will allow the sugar to dissolve, but cooling it again will cause the sugar and/or some of the salt to reform.

You heat water before you mix it because it increases the amount of solute that can be saturated into the solution.
Crystals in general are formed when solutions try to maintain concentrations at or below saturation. For example, a saturated sugar solution forms crystals when water from the solution evaporates and leaves excess sugar behind. Since supersaturation is a highly unstable and thus undesirable state of being for a solution, the dissolved sugar left behind will clump together at sites of nucleation to let the remaining solution remain below supersaturation. Crystals will continue to grow as long as the concentration of solutes in the solution can increase above saturation. To grow large blue vitriol crystals, one can simply prepare a saturated solution in a large container and let it sit undisturbed for as long as possible while evaporating steadily, removing the crystals when they are a satisfactory size or before the solution dries up entirely.
BEFORE it is cooked, the egg white made for a pavlova is BOTH a solution (sugar is dissolved in it) and a colloid.
If gas comes out of solution when a bottle is opened, then there must have been a greater amount of dissolved gas in the substance while it was under pressure prior to opening the bottle.

You can use one of two methods: 1: while making the iced tea, if using a hot tea method and then icing it, add the sugar to the hot tea before cooling. 2: Create a simple syrup. Combine two cups of sugar with one cup of water in a nonreactive saucepan. Heat until the sugar is dissolved (but don't let it boil over!). Then let cool gently. The sugar is now in a super-saturated solution adding sweet cool liquid to your iced tea.
