# How does KNO3 affect solubility?

## How does KNO3 affect solubility?

The curves show that: solubility of all three solutes increases as temperature increases. the solubility of potassium nitrate increases the most from approximately 30 g per 100 g water to over 200 g per 100 g water.

Does KNO3 have a high solubility?

Some solids, such as potassium nitrate, KNO3, have very high solubility. As much as 360g of potassium nitrate will dissolve in one liter of room temperature water.

What is the solubility of KNO3 at 10c?

Task 1: Producing a graph to represent solubility data

Potassium nitrate (KNO3) Sodium nitrate (NaNO3)
Temp. °C g / 100 g water g / 100 g water
10 21 81
20 32 88
30 45 96

### How is solubility of KNO3 affected by temperature?

The solubility of KNO3 in water increases with increase in temperature because soubility of KNO3 in water is an endothermic process. The solubility of CaSO4 in water decreases with the increase in temperature since solubility of CaSO4 in water is an exothermic process.

Why is KNO3 more soluble in water?

1 Answer. This is to do with the fact that KNO3 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.

What is the solubility of KNO3 at 50 C?

80 g/100 g water
The solubility of KNO3 at 50 degrees C is 80 g/100 g water.

#### How is solubility of KNO3 affected by an increase in temperature of the solvent?

The solubility of KNO3 in water increases with the increase in temperature since dissolution of KNO3 in water is an endothermic process. The solubility of CaSO4 in water decreases with the increase in temperature since dissolution of CaSO4 in water is an exothermic process.

What is the solubility of KNO3 at 40 C?

As you can see, potassium nitrate has s solubility of about 67 g / 100g H2O at 40∘C . This means that at 40∘C , a saturated potassium nitrate solution will contain 67 g of dissolved salt for every 10 0g of water.

What is the solubility of KNO3 at 25 C?

Explanation: So, you know that potassium nitrate, KNO3 , has a solubility of 155 g per 100 g of water at 75∘C and of 38.0 g at 25∘C .
