Yes, Benzoic acid is a weak acid (pKa ~ 4.2) that will dissolve in weak base such as sodium bicarbonate (pKa ~ 6.4)
These substances are very different.
No, sodium chloride is not soluble in cyclohexane.
Sodium chloride is not soluble in isopropanol.
Sodium chloride is not soluble in benzene.
Given that pure sodium chloride is a solid at room temperature, no it is not soluble.
Sodium chloride is very soluble in water - approx. 360 g/L at 20 0C.
Sodium chloride is an example of a salt or an ionic compound. It is both.
Sodium chloride is very soluble in hot water.
No that is not true. It is soluble in water.
Sodium benzoate is a water-soluble salt, making it easily extractable in water. On the other hand, benzoic acid is a weak acid that is not as soluble in water as its sodium salt. The addition of sodium hydroxide converts benzoic acid to its more water-soluble salt form, sodium benzoate, which can easily dissolve in water.
No, they are very different substances.
Sodium chloride is very soluble in water because these two substances are polar.
