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.
Well, honey, if that crystal solute was dropped into a solution and dissolved, the original solution became a mixture. The crystal solute basically joined the party and got all cozy with the solvent, creating a new solution. So, in simple terms, the original solution just got a new guest to hang out with.
To make liquid borax, you can dissolve borax powder in hot water. Mix until the powder is fully dissolved and the solution becomes clear. Allow the solution to cool before using it.
The solution is said to be saturated when it contains the maximum amount of solute that can dissolve in the solvent at a given temperature. If there is so much solute that no more will dissolve, the solution is supersaturated. This occurs when additional solute is added beyond the saturation point, leading to a temporary unstable state before the excess solute eventually precipitates out.
The saturation point of sodium chloride is around 26.4% by weight at room temperature. This means that a solution can only hold up to 26.4% of sodium chloride before it becomes saturated and excess salt will not dissolve.
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.)

Maintain a constant temperature during the crystallization process, ensure that the solute is completely dissolved before beginning the crystallization, and provide a suitable environment for crystal formation such as a clean container with no impurities.
No. If a saturated solution is heated, it will no longer be fully saturated. Water at 25°C will be saturated with sugar at a ratio of 100 grams of sugar to 100 grams of water. At 50°C it would take 130 grams of sugar to reach saturation. See this link for a full explanation: http://www.scienceclarified.com/Ro-Sp/Solution.html
When salt has dissolved, the reading of the balance will remain the same as before the salt dissolved. The mass of the salt is still present in the solution, even though it is no longer visible as solid particles.
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.
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.
