How is a particulate formed?

Answer 1

I will assume you are asking about the formation of an ionic compound when two solutions come together. Ions attract at a site of nucleation. All compounds are soluble to some extent (sometimes to a very, very limited extent). We describe this mathematically by the division:

([product 1]*[product 2]) ÷ ([reactant 1]*[reactant 2]) = Ksp (for a perfectly saturated solution)

If the molarities of the actual solution in question exceed Ksp when this calculation is performed, we predict that precipitate will form.

We may encourage particle growth in a number of ways.

You can raise the temperature to decrease the chance of supersaturation. More energy per particle leads to formation of the colloid.

You can mix the species slowly, by either physical or chemical means. This prevents local supersaturation.

You can keep your solutions dilute. This prevents the particles from becoming so small they would pass through a filter.

You can add a soluble background electrolyte. An ionic environment will encourage particles to come together.

Answer 2

Particulates are formed through a variety of processes such as combustion, industrial activities, and natural sources like dust storms and wildfires. Tiny solid or liquid particles, ranging in size from nanometers to micrometers, can be emitted into the atmosphere and then dispersed by wind currents. These particles can have negative effects on human health and the environment.

Answer 3

Particulates are formed from chemical reactions as a result of combustion due to things such as vehicle engines, bonfires, power generators or fireplaces or wood stoves etc.

Answer 4

Particulates are solid particles that float in the air. They come from solids that can be broken down so small that they become airborne. An example is asbestos or fine wood dust.

Answer 5

its formed by acid which is created by oxygen and while the particles form it reacts with steam and reformation.
