Why does a sugar cube dissolve slower when not stirred?
As you are not agitating and breaking away the sugar crystals, the outer layers have to dissolve before the inner layers can, causing the sugar to take longer to dissolve.
Saturated solution will usually dissolve more solid solutes if it is?
A saturated solution will usually dissolve more solid solutes if it is stirred or heated.
What are the effects of stirring on supercooling?
Stirring prevents super cooling by inducing nucleation
What happens to salt when it is put into cold water and stirred?
The cold water becomes salt water. The salt doesn't dissolve like sugar.
What are some examples of things that will affect the time it takes for a solid to dissolve in a solution?
The temperature of the solution, the particle size of the solute, and whether the solution is stirred will all affect the amount of time it takes for a substance to dissolve into solution.
Why did the potassium permanganate crystals start to dissolve in water without being stirred?
because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water Save
Why did the potassium permanganate start to dissolve without being stirred?
Because they have sex

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
Do solids dissolve quicker if the water is stirred?
Yes, stirring help the dissolution.
Can solids dissolve quicker in water if the water is stirred?
No, not at all
How fast does sugar dissolve in hot water not stirred?
around 6-7 mins
Saturated solution will usually dissolve more solid solutes if it is?
A saturated solution will usually dissolve more solid solutes if it is stirred or heated.
How do temperature and stirring affect the solubility of a solute in a solvent?
if the water is hot,the solvent will dissolve faster and when it gets stirred it will dissolve even faster than when it wasn't. but if the water is cold it will dissolve slower than hot water even when stirred.
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.
