It depends what the substances are.
Solubility is the maximum amount of a substance that can dissolve in a given amount of solvent at a specific temperature and pressure. It is typically expressed in units like grams per 100 milliliters of solvent (g/100mL) or moles per liter of solvent (mol/L).
The amount of solute that can dissolve in 100g of solvent will vary as the solubility of different substances vary, but solubility also depends upon other factors such as temperature. For example the solubility for glucose at room temperature is 91g/(100ml).
"Solute per 100g solvent" is the unit given to solubility of a substance.
substance with a low solubility means insoluble substance. solubility of the substance lesser than 0.1g per 100g of water
H2O refers to water. In this solution, 100g of water was used to dissolve 2g of KCl.
The most common unit used to report the solubility of a substance is grams per liter (g/L) or moles per liter (mol/L). This unit quantifies the amount of solute that can dissolve in a given volume of solvent at a specific temperature.
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
To describe the solubility of a gas in a solvent it is directly proportional to the pressure of that gas above the solvent. It is a percentage of mass.There are different ways to define it. One often used is 'Solubility is the number of grams of solute which dissolve in 100g of solute'. You must also specify the temperature.
Assuming the solid is the limiting reagent, the saturation point of the solution is reached when no more solid can dissolve in the solvent, creating a saturated solution. The solubility of the solid must be known to determine if 40g can fully dissolve in 100g of water.
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 also 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.
Approximately 34 grams of KCl can dissolve in 100g of water at 30°C.
An unsaturated solution has excess solvent and can still dissolve more solute.A saturated solution cannot dissolve any more solute, it will simply stay separate.
