What would you like to do?
What temperature is chosen as standard when comparing the solubility of different substances?
At STP(Standard Temperature and pressure), the temperature is zero degrees Celsius(273 Kelvin) and the pressure is 1 atmosphere. At RTP(Room temperature and pressure), the temperature is 25 degrees Celsius(298 Kelvin) and the pressure is 1 atmosphere.

How does temperature affect solubility of a substance which involves endothermic process in forming a solution?
endothermic substances absorb energy when dissolved. Therefore supplying energy(heat) externally will increase the solubility.
Any substance that can be dissolved in water.
amount of solute per amount of solvent
Solubility increases as the temperature increases
Generally, the higher the temperature, the more soluble the solute is.
As the temperature increases the solubility also increases.
because u can
With a rise of temperature, the solubility increases
the soluble substances dissolve in water where as the insoluble substances do not dissolve in water
If there is no reaction occuring to change the molecular structure of the substance, you have to look at the ionic product of the substance. When the ionic product is more tha…n the Ksp of the substance, there would be precipitation of the substance
Most solids become more soluble with increased temperature. Gases, however, become less soluble with temperature as they tend to gain enough kinetic energy to vaporize out of… solution.
The reason antifreeze, as well as other soluble substances, lower the freezingtemperature when added to water, is because they hinder the creation of the hexagonal ice str…ucture. Soluble simply means having the capability of dissolving in a liquid.
Solubility of a substance is the amount of that substance that will be dissolved in a solvent. Solubility is the property of a liquid, solid, or gas.
Substances are soluable if disolving the material will result in 1a decrease in free energy. Kinetics will determine how fact something disolves. For most things they are solu…able because when in solution the are in a lower energy configuration than when they are a solid.
