What is the solubility of sodium chloride at 20 C in water?
36.0 g per 100 g
Solubility is often measured as the grams of solute per 100 g of solvent. The solubility of sodium chloride in water is 36.0 g per 100 g water at 20°C.
What is the solubility of sodium nitrate in 20 C water?
about 85 g/100 mL
From the diagram, the solubility at 20 degree C is about 85 g/100 mL.

|---|---|
| Which compound is most soluble at 20 ºC?, | NaCl (sodium chloride) |
| Which compound is most soluble at 28 ºC?, | KNO3 (potassium nitrate) |
| Which compound is probably a gas? Why?, | Ce2(SO4)3 because its solubility decreases as the temperature of the water increases. |
How much can water dissolve?
Water cannot dissolve an endless amount of solute. A certain amount of water at room temperature can only dissolve up to a certain amount of solute: 1 cup of water can dissolve 1 gram of sugar, 5 grams of sugar, 10, 50, and even 100 grams of sugar; however, 500 grams is too much.
Is the solubility of sodium chloride and potassium nitrate the same?
the solubility of sodium chloride and potassium nitrate is the same at about 23°C (approximately 38 g per 100 g water, where the solubility curves of these substances cross)
What is the solubility of NaCl in 100 ml of water?
That is, at 25°C: solubility in g/100 g water = solubility in g/100 mL water Example: the solubility of sodium chloride (NaCl) in water at 25°C is 36 g/100 mL , or, 36 g/100 g A solute is usually considered to be soluble in water if more than 1.0 g can be dissolved in 100 mL of water.
How is the solubility of water determined at 25°C?
So at 25°C and 101.3 kPa, the solubility of a solute in water given as mass in grams per 100 g water is the same as the solubility of the solute given as mass in grams per 100 mL of water. That is, at 25°C: solubility in g/100 g water = solubility in g/100 mL water
How much solute can be dissolved in 100 ml of water?
A solute is usually considered to be slightly soluble, or sparingly soluble, in water if between 0.1 and 1.0 g can be dissolved in 100 mL of water. The solubility table below gives the maximum mass of solute in grams that can be dissolved in 100 mL of water at 25°C.
