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.

Answer The standard temperature used to measure solubility is 25 °C .
amount of solute per amount of solvent
Generally, the higher the temperature, the more soluble the solute is.
the soluble substances dissolve in water where as the insoluble substances do not dissolve in water
No, different substances are not equally soluble in water. Every solid compound we know of is more or less soluble in water. One good thing to help us measure the amount of wh…ich a compound is solved is the Ksp-value, or the [solvation] rate for the solubility product. This tells us how many moles of the substance is solved in an equal amount of moles of water. Did you know, for an example that there are roughly(1000 g water) / ( 18 g/mole) = 56 moles of water in a litre of water? So, the Ksp-value for water would be 5.6 * 10^1.
Solubility can be written as %m/m (mass in g per 100g), %m/v (mass in g per 100mL), %v/v (mL per 100mL), ppm (parts per million), ppb (parts per billion) etc. Solubility is al…so dependant on pressure and temperature. Due to these variables, in the same units (eg. %m/m) and at the same set of temperature and pressure (SLC or STP) you can compare the solubility values.
If you like dubstep, then sure.
i suppose they could if they held each other in suspension.
Generally, as temperature increases, solubility increases. There are a few cases where the opposite happens, though.
With a rise of temperature, the solubility increases
The short answer is yes it does.
In general solubility increases with temperature. However, thereare exceptions for instance the solubility of Oxygen in waterdecreases with temperature.
