What is the difference between emulsion and salts?

Difference between emulsion and salt

Emulsion

Emulsion is a colloidal dispersion (mixture) of two immiscible(which normally do not mix/unmixable) liquids in which one liquid acts the dispersion medium and the other liquid acts as dispersed phase is called an emulsion.

There are usually of two types

Oil in Water Type

Oil is the dispersed phase,Water is the dispersion medium.

Examples of Oil in Water Type Emulsion: Milk  

Water in Oil Type

Water is the dispersed phase, Oil is the dispersion medium

Example of Water in Oil Type Emulsion: Cod Liver Oil

Salt 

Salts are compounds that are made up two or more ions. Positively charged cations and negatively charged anions make up the salt. They are usually electrically neutral.

There are usually 3 types of salts

Acidic Salts

These types of salts form acidic solutions when they are added to solvents. 

Examples of acidic salts are-Sodium hydrogen sulfate,Sodium dihydrogen phosphate,Disodium hydrogen phosphate.

Uses- They are used as bleaching agents, to prevent corrosion, to treat constipation.

Basic Salts

They are formed due to incomplete neutralization of acid and base

Examples of Basic Salts are:

Sodium carbonate,Sodium acetate,Potassium cyanide,Sodium sulfide,Sodium bicarbonate,Sodium hydroxide 

Uses- Basic salts are generally present in dish washing formulas. (Liquids/Soaps) 

Neutral Salts

As the name suggests they are neutral compounds meaning, they do not carry any charge.

Examples of Neutral Salts: sodium chloride , magnesium sulfate, and ammonium sulfate.

Uses- Sodium Chloride is used in food as an agent which gives salty taste.
