What compound becomes less soluble in water as the temperature of the solution is increased?
Increasing temperature increases solubility so that 480 grams of sugar can dissolve in 100 milliliters of boiling water If you add 240 g of sugar to 50 mL of boiling water the solution will be?
the answer is saturated.
1 Use the Particle Theory to explain what happens to the solubility of a solute as temperature is increased?
Well, as the temperature of water is increased, the more solubility it should have. (this does not always happen, though) This is from the gasses in the heated water sprea…ding apart, which allows more solute to be dissovled. :)
hot water does not hold dissolved oxygen well because the water molecules separate and can't group around the dissolved oxygen, so if oxygen can be considered a solute and wat…er a solvent then the answer is no
Because with an increase in temperature, the solvent molecules have more kinetic energy. This makes it more difficult for a gaseous solute to remain in solution because the… solute molecules are literally ejected by the high energy solvent molecules.
Solubility would increase when temperature increase.ionic solids such as table salt increase in solubility when heated or stirred in a solution.
Temperature is a measurement of the average kinetic energy on the atomic or molecular level; hotter substances have faster moving particles. Faster moving particles have more …energetic collisions with the particles of which solids are formed, which are more able to knock them out of the solid and into the solution, than slower moving particles would be.
Yes, it is true for most of the cases. But when heat is evolved after dissolution of a solute (Exothermic process) or solute is a gas then in such cases solubility decreases… on increasing temperatures.
The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid analogous to melting takes place. Heat i…s required to break the bonds holding the molecules in the solid together. At the same time, heat is given off during the formation of new solute -- solvent bonds.
Although the solubility of most substances increases with temperature (eg you can dissolve more sugar in water when it is hot than you can in the same amount of water when it …is cold) with gases the solubility decreases with temperature, so that cold water will hold more gas than the same amount of hot water. As oxygen is a gas its solubility decreases as the water temperature increases.
It doesn't. As the temperature of water increases so does solubility.
Because when a substance gets hot the molecules spread apart allowing more room for other substances to be mixed in to the solution. for example if you mix water (H20) with ta…ble salt (NaCl) it will fall to the bottom of the liquid unless agitated (stirred) or heated because both of these actions cause molecules to move and spread.
As the temperature of the water increases, its vapour pressure increases, meaning there is more water molecules leaving the surface than before. Gases have weak intermolecul…ar forces and therefore high vapour pressures and will therefore be readily evaporating already. The increased presence of water vapour above the water (i.e. increased humidity) reduces the amount of the gas able to condense back into the liquid, meaning less gas is dissolved.
you need energy to break bonds so by heating the solvent, you provide the energy needed to do this/ Weird Huh?
because their monocles separate causing less density per cubic inch.
Parallelly, in the same way, increase T = increase S
Increasing the pressure on the solution increases its ability to dissolve CO2.
