How much time does it take sugar to dissolve in milk?
It typically takes a few minutes for sugar to dissolve in milk when stirred continuously. The time can vary depending on factors such as the temperature of the milk and the size of the sugar crystals.
Increasing temperature favors dissolution when?
solute dissolves more rapidly in hot water
Why is it that the sugar crystals disappear when stirred in water?
The sugar crystals have no added colour and are 'white' crystals in appearance. Once dissolved into the water, they create a transparent sugary solution. The same is for salt crystals that create a saline solution.
How much time to dissolve the sugar?
The time it takes to dissolve sugar depends on factors like the temperature of the liquid, the size of the sugar crystals, and how vigorously the mixture is stirred. It typically takes a few minutes for sugar to dissolve in hot water, while it may take longer in cold water or other liquids.
Can solids dissolve quicker in water if the water is stirred?
No, not at all
Why did the potassium permanent crystals in Figure 7.12 on page 197 start to dissolve in water without being stirred or shaken?
The potassium permanganate crystals started to dissolve in water without being stirred or shaken because of the process of diffusion. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. The crystals dissolved as their particles spread out and mixed with the water molecules.

Why did the potassium permanganate crystals start to dissolve in water without being stirred?
Potassium permanganate is highly soluble in water, so it will dissolve without needing to be stirred. The dissolution process occurs due to the attraction between the ions in the crystal and water molecules, causing the crystal to break down and disperse evenly throughout the water.
Why does a sugar cube dissolve slower when not stirred?
When a sugar cube is not stirred, the surface area exposed to the solvent is limited, which slows down the rate of dissolution. Stirring increases the contact between the sugar cube and the solvent, allowing the sugar molecules to dissolve more quickly.
Does stirred sugar dissolve faster?
Yes
Will salt solutions dissolve faster if stirred?
yes

What did the powdered drink mix dissolve easily when stirred?
saturated

What are the effects of stirring on supercooling?
Stirring a supercooled liquid can disrupt the formation of ice crystals and trigger the freezing process, resulting in the liquid solidifying at a lower temperature compared to unstirred samples. This is because stirring introduces movement and agitation, preventing the supercooled liquid from remaining in a metastable state.
What happens to salt when it is put into cold water and stirred?
When salt is added to cold water and stirred, the salt crystals dissolve in the water. This process is known as dissolution, where the salt molecules break apart from the crystal structure and mix evenly with the water molecules. It may take longer for salt to dissolve in cold water compared to hot water due to the lower kinetic energy of the molecules.
