Salts are generally ionic compounds.

They often dissolve in water to give electrolyte solutions that conduct electricity.

Not all salts come from strong acids or bases; they can also form from weak acids or bases.

If you want, I can give a short, precise one-line definition suitable for exams. Do you want me to do that?

1. Solvent Extraction

2. Solvent Extraction The image is a diagram illustrating the process of solvent extraction of uranium. This is a method used to separate uranium from other impurities.  The process uses two immiscible liquids: an aqueous phase (impure acidic uranyl nitrate) and an organic phase (tributyl phosphate). 

3. Solvent Extraction The impure acidic uranyl nitrate solution is introduced at the top of one column, while the tributyl phosphate flows counter-current to it.  The uranium selectively transfers from the aqueous phase to the organic phase, leaving impurities like thorium, molybdenum, and tungsten behind in the raffinate.  The uranium-rich organic solvent is then treated to strip the pure uranyl nitrate solution from it.
