Aliquots – Definition, Function, Calculation

Definition and Meaning of Aliquot

An aliquot is a factor of an entire sum, implying that when you isolate the factor into the sum, there is no leftover portion. In the compound and pharmaceutical enterprises, the aliquot technique alludes to allotting a modest quantity of a substance or medication by splitting or weakening, a more significant sum. You figure aliquots when the portion you need is smaller than the base weighable amount (MWQ) of the scale you are utilising, which is based on the scale’s affectability.

For example, there is a grill gathering in hot weather and your native lemonade is very popular. Making one major glass pitcher of lemonade, you choose to spill out two clear glasses and hand them to your visitors. An aliquot is a relevant term to depict these little glasses of lemonade.


Functions Of Aliquot 

An aliquot is a kind of sub-test that is taken or separated from a unique example. If we consider divisions, we can contrast aliquots with the idea of part and entirety. That is, an aliquot is the partial piece of a whole example.

For instance, suppose we have a 20ml arrangement of saltwater (NaCl) and conclude that we need to work with smaller 5ml examples. What might we call these smaller volume tests? The 5ml examples would be our aliquots.

Given what we have found out about part to entire, for what reason do you guess those two glasses of lemonade can be called aliquot examples?

The pitcher of lemonade (i.e., the whole) is isolated out into two distinct parts as it is filled two glasses. Both of these parts are sub-tests of aliquots.

How To Calculate Aliquot?

Figure the scale’s MWQ, which is equivalent to its affectability whose partition takes place by its error. For instance, the MWQ for a 95 per cent exact scale that is touchy down to 6 milligrams (mg) is 6/(1 – 0.95), or 120 mg.

Locate the smallest duplication factor for an individual medication portion by isolating the portion into the MWQ. For instance, assume you have to make five portions of 20 mg each. The factor for a 20 mg portion is 120/20, or 6.

Figure how much diluent – a dormant filler, for example, milk powder – to weigh by subtracting the medication portion from the MWQ and after that increased by the smallest duplication factor. Furthermore, in the model, the measure of diluent to gauge rises to ((120 – 20) x 6), or 600 mg of diluent to be blended with 120 mg of the medication. This produces six dosages; however since you need just five, you would need to dispose of one portion.

Solved Question for You

Q1. Which information is not conveyed by a balanced chemical equation?
     (a)  Physical states of reactants and products
     (b)  Symbols and formulae of all the substances whose involvement takes place in a particular reaction
     (c)  Number of atoms/molecules of the reactants and products formed
     (d)  Whether a specific reaction is feasible or not
A1. The answer is option (d). Any balanced chemical equation does not convey that a particular reaction is feasible or not.
