Yes, salt and other ionic compounds like it will dissolve faster the hotter the water it is dissolved in. This is because hot temperatures make atoms move quicker and the quicker they move, the easier they come apart!

At 0 °C (273.15 K, 32 °F), brine can only hold about 26% salt. At 20 °C one liter of water can dissolve about 357 grams of salt, a concentration of 26.3%. The thermal conductivity of seawater (3.5% dissolved salt by weight) is 0.6 W/mK at 25 °C.

In a solution, the solute is the substance that dissolves, and the solvent is the substance that does the dissolving. For a given solvent, some solutes have greater solubility than others. For example, sugar is much more soluble in water than is salt.

Most solids, including sugar and salt, become more soluble with increasing temperature. This is because heat increases molecular movement, causing more collisions between the water molecules and the solid.

Results. Boiling water (70 degrees) – fully dissolved in the 2 minute period.

If you use too much salt (or too little water) then you will not be able to dissolve all of it. You can add salt slowly to see approximately how much can be dissolved in a given amount of water (at a given temperature). You can dissolve more salt by adding more water or heating it up.

You can safely use vinegar or CLR to remove the salt creep, but the important factors are applying the treatment long enough and using enough elbow grease. Keeping the glass immersed in either vinegar or CLR over a period of time will dissolve the mineral deposits.

Continue running your pool’s filter until the salt dissolves completely. For most standard-sized home swimming pools, this will take 18-24 hours, depending on the water temperature and strength of circulation. Be prepared to wait up to 48 hours for the salt to break down fully in an especially large pool.

Boiling water (70 degrees) – fully dissolved in the 2 minute period. Ice cold water (3 degrees) – the salt crystals shrunk to half the size but did not dissolve.

The a parameter represents the time taken for the sodium chloride sample to dissolve at 0 °C with no stirring, so this result indicated that the sodium chloride sample would dissolve at 0 °C without stirring in 2457 s (40 min 57 s).

There is no obvious difference between the amount of salt that dissolves in the hot water compared to the cold water. This shows that temperature affects the dissolving of sugar more than it affects the dissolving of salt.

Energy, which is the capacity to do work or produce heat, affects the rate at which a solute will dissolve. Breaking up, crushing or grinding a sugar cube before adding it to water increases the sugar’s surface area. This means the finer the sugar particles, the faster it will dissolve.

Sugar dissolves in water at 0 degrees Celsius. This is because sugar is soluble in liquid water at all temperatures at standard pressure.

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water.

1 Answer

1. Increase the surface area of the sugar.
2. Increase the temperature of the water.
3. Stir it up.

The rate of dissolving depends on the surface area (solute in solid state), temperature and amount of stirring.

There are three factors that affect the rate of dissolution: (1) the surface area of the solute, (2) the temperature of the solvent, and (3) the amount of agitation that occurs when the solute and the solvent are mixed.

If you are trying to dissolve a substance, you have three primary avenues to increase the dissolution rate: decreasing the particle size of the solid, increasing the temperature and/or increasing the mixing or stirring rate.

Factors affecting solubility

• Temperature. Basically, solubility increases with temperature.
• Polarity. In most cases solutes dissolve in solvents that have a similar polarity.
• Pressure. Solid and liquid solutes.
• Molecular size.
• Stirring increases the speed of dissolving.

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

Solubility is Affected by pH The pH of an aqueous solution can affect the solubility of the solute. By changing the pH of the solution, you can change the charge state of the solute.

The solubility of a substance fundamentally depends on the solvent used, as well as temperature and pressure. The solubility of a substance in a particular solvent is measured by the concentration of the saturated solution.

The solubility is a measure of the concentration of the dissolved gas particles in the liquid and is a function of the gas pressure. As you increase the pressure of a gas, the collision frequency increases and thus the solubility goes up, as you decrease the pressure, the solubility goes down..

Solubility is defined as the number of grams of the solute that saturates 100 grams of solvent at a given temperature. It has no units. In general a solute dissolves in a solvent if intermolecular interactions are similar in the two substances. Like dissolves like the principle of solubility.

As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of a gas decreases as the temperature increases.

If we heat the solvent, the average kinetic energies of its molecules increases. Hence, the solvent is able to dislodge more particles from the surface of the solute. Thus, increasing the temperature increases the solubilities of substances. For example, sugar and salt are more soluble in water at higher temperatures.

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Temperature. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
