Is sugar a solution?
No, sugar is not a solution. Sugar water is a solution of sugar and water, but sugar itself is not.
How could you obtain sugar crystals from the sugar solution without losing the ethanol?
By heating ethanol is evaporated and sugar remain as a solids.
How could you demonstrate that a sugar solution is just saturated?
You can keep adding sugar, if it dissolves it is still unsaturated and if it piles up at the bottom of the glass it is saturated. you can also freeze the solution or cause it to precipitate
What happens when sugar dissolve in water?
Sugar becomes what is know as aqueous( dissolved in solution with the water) this is the process of water molecules breaking and surrounding ions in he sugar so for each sugar molecule several water molecules will be bonded to it thus why if you put enough sugar into water it cant dissolve all of it as there are not enough water molecules to surround the sugar.
When a few spoonful of sugar are mixed into a cup of water what is the sugar?
Redered radioactive, due to the formation of positrons and neutrinos as the sugar is ionized.
Can sugar be obtained from a sugar solution by heating the sugar solution and evaporating the water explain?
Yes - the sugar doesn't evaporate.
How do you dissolve more sugar cube in a glass of saturated sugar solution?
By heating the saturated sugar solution, and then adding more sugar.
What will happen to sugar after heating?
it will become caramel
Can sugar be seperatd from sugar solution?
Yes, sugar can be separated from a sugar solution through a process called evaporation. By heating the solution, the water will evaporate, leaving behind the sugar crystals. The crystals can then be filtered out to separate the sugar from the solution.
What will happen after heating the sugar?
It turns to a brownish color and smokes
Can sugar solution be separated using evaporation?
Yes, sugar solution can be separated using evaporation. By heating the solution, the water will evaporate leaving behind the sugar crystals. This process is commonly used to extract sugar from sugarcane juice to produce refined sugar.
What happen after the sugar solution evaporated?
The Sugar will be left at the bottom and the liquid will be gone.
Does benedict's solution need heating when testing for glucose?
Yes, Benedict's solution needs heating to test for glucose. Heating helps to facilitate the reaction between glucose and the copper ions in the Benedict's solution, resulting in a color change that indicates the presence of glucose.
What would happen if an aqueous solution of sugar is heated to dryness?
Crystals of sugar are obtained.
What happen to sugar when it is mixed with water?
Sugar dissolves in water to form a homogeneous solution.
Why a saturated solution on heating becomes unsaturated explain and give example?
When a saturated solution is heated, the solubility of the solute generally increases due to the temperature dependency of solubility. This results in the solution no longer being saturated and more solute being able to dissolve. For example, if you have a saturated sugar solution at room temperature and then heat it, more sugar molecules can dissolve in the solution because solubility of sugar increases with temperature, making it unsaturated.
What would you do to obtain pure dry sugar crystals from a sugar solution?
To obtain pure dry sugar crystals from a sugar solution, you can evaporate the water by heating the solution until the water has completely evaporated, leaving behind sugar crystals. You can then filter the solution to separate the sugar crystals from any remaining liquid. Finally, allow the sugar crystals to dry completely to ensure they are pure and free of any residual moisture.
