## How do you answer a solubility curve question?

Definition of solubility curve : **a graphic representation of the variation with changing temperature of the solubility of a given substance in a given solvent.**

## What is the solubility curve?

ABWhen 50 grams of potassium chloride, KCl, is dissolved in 100 grams of water at 50 xbaC, the solution can be correctly described as:,**supersaturated**17 more rows

## When 100 grams of Kno₃ is dissolved in 100 grams of water at 50 ºC the solution can be correctly described as?

Aqueous solutions may be classified as **saturated, unsaturated or supersaturated. Saturated- the maximum mass of solute that can be dissolved in a certain volume of solvent at a certain temperature. Unsaturated- solution contains less than the mass stated above.**

## How do you interpret a solubility curve?

**Trace the solubility of a substance with increasing temperature.**

- The curved line represents saturation.
- Below the curve, the solution is unsaturated.
- Above the curve the solution is supersaturated. This means there is more solute than the solution can hold.

## What is solubility question answer?

Explanation: Solubility is **the maximum amount of solute that can be dissolved in a given solvent at a particular temperature and pressure. It is usually expressed in grams of solute dissolved in 100 grams of the solvent.**

## What is an example of solubility curve?

Solubility curves can be used to determine if **a given solution is saturated or unsaturated. Suppose that 80g of KNO3 is added to 100g of water at 30oC. According to the solubility curve, approximately 48g of KNO3 will dissolve at 30oC. This means that the solution will be saturated, since 48g is less than 80g.**

## What is solubility curves give their uses?

Solubility curves can be used to determine if **a given solution is saturated or unsaturated. Suppose that 80g of KNO3 is added to 100g of water at 30oC. According to the solubility curve, approximately 48g of KNO3 will dissolve at 30oC. This means that the solution will be saturated, since 48g is less than 80g.**

## What solution do you have if you dissolve 50 g of nh4cl in 100 grams of water at 50 C?

saturated solution

## What happens to a solution of KNO3 that is saturated at 50 C when it is cooled quickly to 10 C?

Since you have less potassium nitrate than that, your solution will be unsaturated. When you cool the solution to 10u2218C , **potassium nitrate’s solubility decreases significantly**

## How many grams of KNO3 can dissolve in 100g of water at 50c?

(d) Initially there is 100 g of potassium nitrate in solution, at 50 the solubility is **84 g/100g (original data or graph), so 16 g will have crystallised out.**

## How many grams of KNO3 will dissolve in 100g of water at 40 C?

As you can see, potassium nitrate has s solubility of about **67 g / 100g H2O at 40u2218C .**
