What is a coagulating agent?
Answer:
It is something that either causes existing groups of molecules to stick together, making the solution thicker, or causes a chemical reaction making larger molecules that then stick together.
Either way, the solution becomes thicker and may also separate into a thin layer and a thick or even solid one.
just that, it is the chemical or compound
that causes a liquid, such as blood to coagulate, or thicken.
A coagulating agent forces small particles to bunch together into larger particles. There are a few ways of doing this:
1. it can change the ion concentration around the particles
2. It can form a bridge between the particles
3. It can change the surface voltage of the particles.
lemon juice is a good coagulating agent for milk.
Often alum is used to coagulate things. There are some other chemicals that can be used also. Even salt will sometimes work.
Essentially a coagulating agent causes small molecules to form a polymer or chain of the small molecules which become subunits of the polymer.
