How do you find the solubility of KNO3?
Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g . Solubility of NaNO3=21.9g or NaNO3 x 100 g/ 25 g =87.6. Calculate the molar mass of the dissolved compound as the sum of mass of all atoms in the molecule.

| 40 | 63 | 105 |
Is KNO3 more soluble in water?
the solubility of potassium nitrate increases the most from approximately 30 g per 100 g water to over 200 g per 100 g water. the solubility of sodium chloride hardly changes at all. sodium chloride and lead(II) nitrate are more soluble than potassium nitrate at low temperatures.
Is kno soluble in water?
KNO3 is soluble in water, glycerol and ammonia and slightly soluble in ethanol.
Is pbno32 soluble in water?
Pb(NO3)2 is soluble in water. This compound forms white, colorless crystals at standard temperature and pressure. It is produced from the reaction of metallic lead or lead oxide, PbO, in a solution of nitric acid, HNO3.
Which substance is least soluble at 60 C?
Answer Expert Verified Seeing the above records we can easily say that the solubility of KClO3 is the lowest at 60 degree centigrade.
Which substance is most soluble at 20 C?
Do I Know about Solubility Graphs?
| A | B |
|---|---|
| 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. |
What does the solubility of KNO3 depend on?
This is to do with the fact that #KNO_3# is an ionic compound. Ionic compounds dissolve in water and covalent compounds do not. The best example of this is NaCl (Sodium Chloride: table salt) – this is an ionic salt and dissolves readily in water. A covalent compound such as sand (Silicon Dioxide: #SiO_2#) does not dissolve in water.
What is the solubility of potassium nitrate in water?
