Oil, being a non-polar covalent compound is not soluble in water, which is a polar solvent. Salts (not limited to NaCl, but all ionic salts,) being ionic compounds that disassociate in solution to form charged ions, are highly soluble in water.
Salt is not soluble in baby oil because baby oil is a nonpolar substance, while salt is a polar substance. Polar substances dissolve best in other polar substances, and nonpolar substances dissolve best in other nonpolar substances. In this case, the polarity difference between salt and baby oil prevents them from mixing or dissolving into each other.
No. By definition, a mineral must be a solid and have crystals
Salt, also know as Sodium Chloride or (NaCl).
No. Because of the confusion between turpentine, mineral turpentine, mineral spirits and mineral oil, I have included links to all of these substances. All of the above except mineral oil are toxic if one drinks them. Turpentine is the only one that is not a petroleum distillate. Mineral oil as sold in a pharmacy is for constipation and to be used as directed. See related links.
halite
No
no
When oil and salt mix, the salt will not dissolve in the oil because they are immiscible. Instead, the salt will sink to the bottom of the container, creating a separate layer from the oil. The oil will not change in appearance or consistency.
purple.
no
Baking soda dissolves faster than salt.
The solubility in most of these is quite low. (Please see the link.)
The reason why salt cannot disolve in water , is because salt is a mineral, and minerals do not disolve in water.
no it can not
I don't know what these samples are of, but somethings just dissolve in oil but not in water. That's one of the properties they have.
Yes, naphthalene crystals are soluble in mineral oil, as both are nonpolar substances. When naphthalene is added to mineral oil, it dissolves to form a homogeneous solution.
halide ions strongly interact with the counter-ions. However, mineral oil is non-polar. To dissolve the halide ions (and the counter-ions) into mineral oil would drastically raise system energy. Thus it does not work. More simply, halide ions have a charge and won't easily dissolve in non-polar substances, since like-dissolves-like.
