Is sodium nitrate or potassium nitrate more soluble?
sodium chloride and lead(II) nitrate are more soluble than potassium nitrate at low temperatures.
How does the solubility curve for sodium chloride compare with the solubility curve for potassium nitrate?
The solubility curve of sodium chloride is very flat compared to the curve for potassium nitrate. Temperature has a very slight effect on the solubility of sodium chloride.
Which is more soluble potassium nitrate or potassium chlorate?
So, more energy is needed to break the bond between potassium chloride than potassium nitrate. Hence, lattice enthalpy is more in case of potassium chloride and thus more water is needed to dissociate the bonds. So, potassium chloride is less soluble in water.
Which is more soluble KNO3 or NaCl?
Sodium chloride will be more soluble in water since a greater amount of it can dissolve in 100 grams of water as compared to potassium nitrate.
Which substance is most soluble at 20 degrees Celsius?
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. |
Which salt is least soluble at 50 ºC?
Do I Know about Solubility Graphs?
| A | B |
|---|---|
| What is the solubility of potassium nitrate, KNO3at 70 ºC?, | about 132 g/100 mL water |
| At what temperature can 100 mL of water first dissolve 50 grams of potassium chloride?, | about 80 ºC |
| Which compound is least soluble at 50 ºC?, | NaCl (sodium chloride) |
Is the solubility of sodium chloride and potassium nitrate the same?
the solubility of sodium chloride and potassium nitrate is the same at about 23°C (approximately 38 g per 100 g water, where the solubility curves of these substances cross)
Which is more soluble in water NaCl or NaCl?
Moreover, this compound is easily soluble in water and makes a salty solution. Aqueous sodium chloride and molten sodium chloride can conduct electricity due to the presence of ions. The production of NaCl is normally via evaporating sea water. Moreover, we can produce this compound by chemical methods, such as adding HCl into sodium metal.
Which is more electropositive potassium chloride or sodium chloride?
Summary – Sodium Chloride vs Potassium Chloride. Potassium chloride is KCl and sodium chloride is NaCl. Potassium is more electropositive than sodium, so the electronegativity difference between K and Cl is higher than that of Na and Cl. 1. “Sodium Chloride.” National Center for Biotechnology Information.
How to calculate the solubility of a saturated solution?
At 10oC, 80 g of NaNO3 will dissolve in 100 mL (a saturated solution) To find the # grams needed to saturate a solution when the volume is NOT 100 mL use the following strategy to find answer: Start w/ known vol. x Solubility/100mL at set temp. = amount of Solute needed to saturate
