reducing the concentration of a chemical
Water can dilute an ETG test. However, you will have to drink a large amount of water for the dilution process.
Means that there is no dilution.
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.

the dilution of two or more solutions of sulfate and chemical microbial sists of plaque
It's to see if you have VD.
They certainly can--they use an adulteration test.

1. dilution error 2.blame the test sample 3.poor maintenance of bottles(cleaning)
That is a good question! The answer is simple. You do step by step dilution of the serum with probably normal (isotonic) saline solution and test the same for Widal test. This is how you do quantitative test for many other tests also.
Phenol coefficient test is best known screening test in which potency of a disinfactant is compared with that of phenol. A series of a dilutions of phenol and the disinfactant being tested are prepared. A standard amount of Salmonella tyhpii and Staphylococcus aureus are added to each dilution; the dilutions are then placed in a 20 to 37oC water bath. At 5-minute intervas, samples are withdrawn from each dilution and used to inoculate a growth medium, which is incubated for two or more days and then examined the growth. If there is no growth in the growth medium, the dilution at that particular time of sampling killed the bacteria. The highest dilution that kills the bacteria after 1o min. expousre, but not at 5min. is used to calculate the phenol coefficient. This is done by dividing the resiprocal of the appropriate phenol dilution.
dilution will reduce the viscosity The effect of dilution on viscosity of oil is that it will decrease.
