The ion-ion bond in CaSO4 is stronger than in NaCl because of the higher charges on the cation and anion.

Be careful in making this argument. The ion-dipole forces of Ca2+ -H2O and SO42- - H2O might actually be stronger than that of Na+ -H2O and Cl- -H2O due to the high charges on Ca2+ and SO42- . However the strengths of the ions-dipole interactions do not match (or exceed) the strength of the Ca2+ -SO42- ionic bond.

Does calcium sulfate dissolve in water?

Very poorly soluble. With increased temperature even less.


How do you prepare .9 sodium chloride solution?

You take 1.00 mole NaCl, this is 58.45 grams dry substance NaCl, and add (while dissolving) up to 1.00 L water (so you'll need about 0.95 L -LESS than 1.00 L- of water).


Why is Cl2 less soluble than HCl?

Because, HCl (Hydrochloric acid) Is a VERY strong acid. It is soluble in very few things. Most things are soluble IN HCl. Not the other way around. The more acidic it its, the less soluble it is.


Suggest reasons why recrystallization from water would probably not be suitable procedure for purifying nacl caco3 c2h6o?

Starting with NaCl, Sodium and Chlorine have a large difference in electronegativity, which means in the polarity of water will be able to break the polar NaCl bond. In ethanol, C2H6O, there is enough difference in electronegativity between the Carbon and Oxygen for the polarity of the water molecule to break this bond. In CaCO3, it is the Carbon and Oxygen bonds again the break. This is far less soluble than the other two molecules, but the same reason still applies. For recrystallisation, try something non-polar to wash your crystals, like hexane. If you were wanting to recrystalise the calcium carbonate, ice-cool distilled water would be fine and wouldn't drastically decrease your % yeild.


Is BaCl2 plus Na2SO4 a redox reaction?

Assuming that the intended reaction is BaCl2 (aq) + Na2SO4 (aq) => 2 NaCl (aq) + BaSO4 (s), this is not a redox reaction. Instead it is an ion interchange reaction, driven by the fact that BaSO4 is much less soluble in water than any of the other ions pairs barium chloride, sodium chloride, and sodium sulfate.

Why nacl is less soluble in heavy water than in water?

Sodium chloride (NaCl) is less soluble in heavy water (D2O) compared to regular water (H2O) because the heavier isotopic composition of deuterium in heavy water disrupts the ionic interactions between Na+ and Cl- ions, resulting in weaker solvation and lower solubility. The increased mass of deuterium also alters the hydrogen bonding network in heavy water, which further hinders the dissolution of NaCl.


Is calcium fluoride soluble in water?

Calcium fluoride is considered sparingly soluble in water, with a solubility of about 16 mg/L at room temperature.


What is the pH of CaSO4?

Calcium sulfate (CaSO4) is a neutral salt that does not significantly affect the pH of a solution when dissolved in water. The pH of a solution containing CaSO4 would be near neutral, around 7.


Which sugar is less soluble in water?

Sugars with increasing carbon units tends to be less soluble in water like polysaccharides.


Is oil soluble in water at elevated temp?

I think oil will be less soluble in water at elevated temperatures.


Why wax is more stable in water and unstable towards heat but NaCl solid is less stable in water but highly stable in heat?

Wax is an organic molecule made up of nonpolar covalent bonds. So it is not soluble in water and has a reasonable melting point. NaCl is an inorganic salt made of ionic bonds. Because water is polar it can dissolve NaCl. Ionic bonds are very strong though, and so it has a high melting point.


When will salt become less soluble in water?

Is calcium hypochlorite soluble?

It has very less water solubility


Why is glucose more soluble in water than cyclohexanol?

Glucose is more soluble in water than cyclohexanol because glucose is polar. In contrast, cyclohexanol is mostly nonpolar and therefore less soluble in water.


Water insoluble fertilizer?

A fertilizer for agriculture must be soluble in water, more or less.


Why iodine is more soluble in cl but less soluble in water?

Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.


Is salt soluble in water?

Yes, salt (sodium chloride) is highly soluble in water. When added to water, salt dissociates into its ions (sodium and chloride) which can dissolve readily in the water, making it a soluble substance.
