In brief:
Plants produce glucose through photosynthesis. Sugar is a form of glucose.
Adding sugar water to a plant does, in the short term offer small benefits as the plant is able to absorb small amount of glucose instead of using photosynthesis to produce it.
Long term use of sugar water on plants will result in the death of the plant! To much sugar in the soil solution prevents or hampers osmosis, resulting in ineffective water and nutrient uptake by the plant. This results in discolouration, stunting, wilting and eventually death.
Damage to the root system can be compounded as sugar offers a very good medium for fungal and bacterial colonies to develop in the soil, which my further damage a weakened root system.
One of the main products of desalination is fresh water, which is obtained by removing salts and other impurities from seawater or saline groundwater. Desalination can also produce brine, a concentrated salty solution that remains after the removal of fresh water.
A 10% bleach solution can be effective for disinfection for up to 24 hours, after which its potency starts to decrease. It is recommended to prepare a fresh solution each day for optimal disinfection results.
In desalination, the process of removing salt and other impurities from seawater or brackish water occurs. This is typically achieved through methods such as reverse osmosis, distillation, or electrodialysis, where saltwater is separated into fresh water and concentrated brine through different physical and chemical processes, rather than a chemical reaction.
To prepare fresh ferrous sulphate, dissolve ferrous sulphate heptahydrate crystals in water with gentle heating, stirring until completely dissolved. Allow the solution to cool and filter out any insoluble impurities. Store the solution in a tightly sealed container away from light and moisture.
Starch solution can generally be stored for up to one week in the refrigerator. After this time, the solution may start to break down and lose its structural integrity. It is best to prepare fresh starch solution as needed for optimal performance in experiments.
when the grapes are soaked in water they become hypotonic and absorb water because they have a higher solute concentration than the water therefore the water diffuses into the grape. once moved to the salty solution, the solute concentration will be higher in the salt solution then the grape so then the grape will become hypertonic and water in the grape will diffuse into the solution to try to create homeostasis
When fresh raisins are placed in a concentrated sugar solution, water will move out of the raisins and into the solution through osmosis. This process occurs because the sugar solution has a higher solute concentration than the inside of the raisins, causing them to lose moisture. As a result, the raisins will shrivel and become less plump. Additionally, the concentrated sugar may begin to draw out some of the flavors and sugars from the raisins, potentially altering their taste.
Yes.

it dies since it enters a hypotonic solution thus making it shrink
2.5 kg 20 kg fresh grapes will contain 2 kg of grapes and 18 kg water. In dried grape, grape concentration is 80%; that implies 2kg should be taken as 80%. So, total weight of dried grape is 2.5kg.

By drinking fresh water.
Fresh grapes do not significantly increase in sweetness if left out at room temperature. While they may become slightly softer and lose some moisture, which can concentrate their sugars, the overall sugar content remains relatively stable. For optimal sweetness, grapes are best enjoyed fresh and chilled.
Fresh and ripe are the adjectives describing the noun grapes.
Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. To illustrate, imagine a semipermeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side. Reverse osmosis is often used in commercial and residential water filtration. It is also one of the methods used to desalinate seawater. Sometimes reverse osmosis is used to purify liquids in which water is an undesirable impurity (e.g., ethanol).
no, not necessarily, but if you do refrigerate grapes it helps keep them fresh and they will last longer.
