Question

what is colloids give a long long long explanation ​

Answer 1

Answer:

In chemistry, a colloid is a phase separated mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). Unlike a solution, whose solute and solvent constitute only one phase, a colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension) that arise by phase separation. Typically, colloids do not completely settle or take a long time to settle completely into two separated layers.

Answer 2

Answer:

A colloid may be a mixture of one substance that may spread out evenly inside another substance. They may be in two different phases or states of matter.

One substance can be the dispersion medium, such as water or gas. The other is kind of dispersed medium, sometimes called the 'internal phase'. This is never tiny solid particles. Otherwise, if the dispersion medium is a gas, then the internal phase may be either tiny particles or tiny droplets of a liquid.

A colloid is a substance microscopically dispersed evenly throughout another substance. The dispersed-phase particles have a diameter between about 5 and 200 nanometers.

Examples:-

• Milk is an emulsion, which is a colloid in which both parties are liquids.

• Shaving cream and whipped cream are colloids of gas inside a liquid.

• Gels, such as agar, jelly or even opals, are colloids of liquids inside solids
