Is KNO3 soluble or insoluble

Answer 1

no (yes! - lordwelsh)

13.3 g/100 mL (0 °C)

36 g/100 mL (25 °C)

247 g/100 mL (100 °C)

Here are some solubility rules in case you need to know other compounds' solubility:

1. All alkali metal (lithium,sodium,potassium,rubidium, and cesium) and ammonium compounds are soluble.

2. All acetate, perchlorate, chlorate, and nitrate compounds are soluble.

3. Silver, lead, and Mercury(I) compounds are insoluble.

4. Chlorides, bromides, and iodides are soluble.

5. Carbonates, hydroxides, oxides, phosphates, silicates, and sulfides are insoluble.

6. Sulfates are soluble except for calcium and barium.

The first rule states it is soluble because it has potassium. But in other cases two rules will say different things. Like on will say soluble and one will say insoluble so always follow the first one listed.

A more specific example is AgCl. Rule 3 overtakes rule 4 so it is insoluble.

Answer 2

Calcium nitrate is soluble in water.
