Which is the more soluble in water NaF or LiF?

NaF is more soluble than LiF because of the larger size of NaF. LiF is formed by a lithium cation and a fluoride anion, and NaF is formed by a sodium cation and a fluoride anion. Therefore, NaF is more soluble in water than LiF.

Which is more soluble in water NaCl or NaI?

Since size of ions is inversely proportional to the lattice energy, Na+ and I- ions in NaI will require less energy to break away from the lattice as compared to Na+ and Cl- ions in case of NaCl. So, in one statement- NaI has better solubility due to lesser requirement of energy in order to break its lattice.

Why is NaF less soluble than NaCl?

The solubility trend of the sodium halide salts (NaF, NaCl, NaBr, NaI) is that the solubility increases with increasing ionic radius of the halide. This means the solubility increases down the halogen group when they are bonded to sodium ions. NaBr is more soluble than NaCl and NaCl is more soluble than NaF.

Which has more solubility in water?

Among the given compounds, sugar is the most soluble compound in water.

Which of the following is least soluble in water NaF?

LiF is the least soluble among the fluorides of alkali metals.

Why NaCl is soluble in water but NaI is not?

Water can dissolve salt because the negative chloride ions are attracted by the positive portion of water molecules and the positive sodium ions are attracted by the negative portion of water molecules. Iodine has a very low solubility in water because it is non-polar. Hence, low solubility.

Why NaI is more soluble in water?

Due to smaller size of Li+ cation, it polarizes the I- anion more strongly than Na+ cation. So, covalency character of LiI makes it less soluble in polar solvent water. By contrast, due to larger size of Na+, more ionic character of NaI makes it more soluble in polar solvent water.

Why are some elements more soluble than others?

Compounds with small ions tend to be less soluble than those with large ions. If the water molecules have a greater attraction to the ions than ions have for each other, then the compound will be soluble in water. Compounds with small ions are less soluble than compounds with large ions.
