What is the solubility of KNO 3 at 50 C?
80 g/100 g
The solubility of KNO3 at 50 degrees C is 80 g/100 g water.
Which chloride is the most soluble at 10c?
potassium chloride
Explanation: At 10 ∘C , the solubility of potassium chloride is measured to be 31.2⋅g per 100⋅g of water.
What is the solubility of potassium nitrate in 5 C water?
The solubility is about 90 g of KNO₃ per 100 g of water.
What is the solubility of NaNO3 at 10c?
At 10oC, 80 g of NaNO3 will dissolve in 100 mL (a saturated solution) • Say we only needed 60 mL of a NaNO3 solution. Other Useful Information: Solutes whose curves move upward with increased temperature are typically solids because the solubility of solids increases with increased temperature.
Is NaNO3 or KNO3 more soluble?
NaNO3 because the higher line indicates that more NaNO3 can be dissolved. 3. The line marks the saturation point of a solute in 100 grams of water. The graph indicates that 104 grams of KNO3 will dissolve in 100 grams of water, so I only need 104/2 = 52 grams of KNO3 to make my solution.
What is the solubility of potassium nitrate in 40 C water?
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 kclo3 at 70 C?
According to the solubility curve, 100 g of water can hold up to 30 g of the KClO3 in the soluted state at 70 °C.
Which compound is least soluble in water at 10c?
The compound which is the least soluble at 10°C is GRAH! 12. A saturated solution of potassium chlorate is made at 10°C by dissolving the correct mass of salt in 100 mL of water.
What is the solubility of potassium nitrate in 10 C water?
Task 1: Producing a graph to represent solubility data

Potassium nitrate/Soluble in
Properties. Potassium nitrate has an orthorhombic crystal structure at room temperature, which transforms to a trigonal system at 129 °C (264 °F). Potassium nitrate is moderately soluble in water, but its solubility increases with temperature.
What is the solubility of ce2 so4 3 at 10 C?
The solubilities at 10 °C and 50 °C are 14 g/100 mL water and 6 g/100 mL water, respectively.
