What is chemical agitation?

What is chemical agitation?

agitation in Chemical Engineering Agitation is the movement of one or more components of a mixture to improve contact. Vigorous agitation of liquids, particularly water, will cause a reduction in the agglomeration of the liquid and change its normal properties.

What is mechanical agitation?

Mechanical agitation may be used to suspend particles in a liquid in order to promote mass transfer or a chemical reaction. The liquids involved in such applications are usually of low viscosity, and the particles will settle out when agitation ceases.

What is a simple definition of an emulsion?

emulsion, in physical chemistry, mixture of two or more liquids in which one is present as droplets, of microscopic or ultramicroscopic size, distributed throughout the other. A simple way to make and reconfigure complex emulsions.

What is agitation speed?

[′aj·ə‚tād·iŋ ‚spēd] (mechanical engineering) The rate of rotation of the drum or blades of a truck mixer or other device used for agitation of mixed concrete.

What is agitation method?

Agitation (action), putting into motion by shaking or stirring, often to achieve mixing. An emotional state of excitement or restlessness. Psychomotor agitation, an extreme form of the above, which can be part of a mental illness or a side effect of anti-psychotic medication.

What is agitation and mixing?

Generally, agitation refers to forcing a fluid by mechanical means to flow in a circulatory or other pattern inside a vessel. Mixing usually implies the taking of two or more separate phases, such as a fluid and a powdered solid or two fluids, and causing them to be randomly distributed through one another.

What is agitation used for?

In addition to “mixing”, agitation is often used for the purpose of “homogenization” (making an emulsion, a suspension, or a dispersion) and “mass transfer” (promotion of reaction and dissolution). In everyday life, either whippers or electric mixers are used during cooking.

What is mixing and agitation?

Agitation and mixing  agitation is a means whereby mixing of phases can be accomplished and by which mass and heat transfer can be enhanced between phases or with external surfaces  Mixing is concerned with all combinations of phases of which the most frequently occurring ones are 1. GASES WITH GASES 2.

How do you test for emulsion?

The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve (lipids are soluble in alcohols). The liquid (alcohol with dissolved fat) is then decanted into water.

What are types of emulsion?

There are two basic types of emulsions: oil-in-water (O/W) and water-in-oil (W/O). These emulsions are exactly what they sound like, as pictured below. In every emulsion there is a continuous phase that suspends the droplets of the other element which is called the dispersed phase.

What is agitation scale?

The basic premise of the “scale of agitation” is that a value of 1 represents the minimum intensity necessary for complete motion of the liquid; a value of 10 represents the maximum practical intensity, although higher intensities might be used for extreme cases.

What is agitation in pharmacy?

An emotional state of excitement or restlessness. Psychomotor agitation, an extreme form of the above, which can be part of a mental illness or a side effect of anti-psychotic medication.

What are the tests for identification of the type of emulsion?

Tests for identification of the type of emulsion. 1 1.dilution test-. the emulsion is diluted with water if the emulsion remains stable after dilution it is o/w emulsion. If emulsion breaks on dilution 2 2.dye test-. 3 3.conductivity test-.

What happens if emulsion breaks on dilution?

If emulsion breaks on dilution it is w/o type. the scarlet dye is used in this test this dye is mixed with emulsion then place a drop of it on a microscopic slide and cover with a cover of sleep. And examine under the microscope.

How do you know if an emulsion is electrically conductive?

An o/w emulsion will conduct electricity as water conducts electricity, but a w/o will not conduct electricity. 3) Dye test In this, a water-soluble dye is added to the emulsion. If it is an o/w emulsion, the dispersion medium appears red and the dispersed phase colourless and vice-versa.

How do you determine the phase of an oil continuous emulsion?

This can be established by adding either water or kerosene to the sample: whichever fluid dilutes and mixes with the emulsion is the continuous phase. Adding water to oil continuous emulsion will not result in dilution and the water will simply drop to the bottom as a free, un-combined phase.
