Is sugar dissolved in water is it a mixture but not a solution?
Sugar dissolved in water forms a homogeneous mixture known as a solution. In a solution, the sugar particles are evenly distributed throughout the water, resulting in a uniform composition. Thus, sugar dissolved in water is classified as a solution.

How does sugar lower water activity?
When sugar is added to a solution, it competes for water molecules, thus reducing the amount of available water for microbial growth. This lower water activity (aw) makes it harder for bacteria, yeast, and mold to thrive since they need water to grow and reproduce.
How do you obtain big crystals of blue vitriol from its solutions?
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.
Does kinetic energy help sugar dissolve more quickly?
The kinetic energy is only very slightly involved in dissolving sugar. What is important is that stirring mixes the solution and the liquid close to the sugar will not get saturated because it is being mixed with all the other liquid. the grains of sugar will present more surface area to the solvent (they will be mixed up in it and not settle to the bottom of the mixing vessel) thus the grains will dissolve faster if they are stirred vigorously. The heat energy added to the solution from stirring plays a very minor role.

Is sugar syrup a base or acid?
As termed, Sugar SOLUTION. Here solution means that sugar is added to water and thus, is soluble in it, hence, it is an alkaline. Alkaline means it is a base. Therefore, Sugar Solution is a base.
What can be done to a sugar solution to make it more concentrated?
To make a sugar solution more concentrated, you can heat the solution to evaporate some of the water content, thus increasing the ratio of sugar to water. Another way is to keep the solution in an open container to allow water to evaporate naturally, leaving behind a more concentrated sugar solution.
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.

What happens if you put too much sugar in tea scientific?
You would super saturate the solution and the excess would not stay suspended. Thus the sugar you find at the bottom of your teacup.
Why can hot tea hold more sugar than cold tea?
I am not sure what they are looking for here. The general answer is because the solvent constant is dependent on temperature. The molecular answer is that temperature is a measure of the kinetic energy present in solution. Increasing the kinetic energy in solution increases the chance that a water molecule will collide with the sugar with sufficient force to dissociate the molecules of 'sugar' from each other, thus allowing it to dissolve is solution.
How does surgar help in a jam?
the concentrated solution of sugar and water provides an environment that creates an osmotic pressure on the cell walls of the microorganisms thus dehydrating them and inhibiting there growth
Will milk jugs sink or float in sugar water?
Sugar water is denser than plain water. A saturated solution -- it will not absorb one more gram of sugar -- is about 1.83 grams per milliter. Whole milk's density is 1.034 grams per milliliter. Thus a full jug of milk (assuming a thin plastic jug, not a heavy glass container, and no air in the jug) would float on sugar water. How far it would sink depends on the concentration of the sugar solution.
Why are mixtures (such as sugar in water) not given chemical formulas?
If the sugar and water are considered a mixture, they are thus comprised of different parts, and a single chemical formula cannot be reached. However, if every molecule of water is connected in some way to a molecule of sugar, then the substance is a solution, and a chemical formula may be given.
Why a saturated solution on heating becomes unsaturated explain and give example?
On heating a saturated solution it becomes unsaturated because heating causes kinetic energy to increase the distance between the molecules of liquid. Thus the solute takes free space present in the solvent. That is why saturates solution becomes unsaturated upon heating.
How do you separate a mixture sugar and sand?
Boil the mixture in water. Then put the solution through a coffee filter. This will separate the sand from the water, which will have the sugar dissolved in it. Then let the water sit in sun, allowing the water to evaporate, thus leaving the sugar crystals. Wa-la, you have separate the sand from the sugar.filtration and simple distillation will do. add water to the mixture to dissolve all the sugar. then filter the solution with the use of a filter paper or a fine cloth. the sand will remain with the cloth while the dissolved sugar will pass through the cloth with the water. boil the sugar solution. when all the water evaporates the only thing that will be left in your container is the sugar.filtration and simple distillation will do. add water to the mixture to dissolve all the sugar. then filter the solution with the use of a filter paper or a fine cloth. the sand will remain with the cloth while the dissolved sugar will pass through the cloth with the water. boil the sugar solution. when all the water evaporates the only thing that will be left in your container is the sugar.A solution of sugar and sand can easily be separated by first adding water to this mixture and then filtering it .Doing this will leave behind sand as the residue and sugar and water as the filtrate.Sugar and water can then be easily separated by evaporating the water leaving behind the sugar.
