Natural water is acidic and tap water can contain some toxic material but we require deionized water and water free from any toxic material
That's why we don't use both of these waters
Water can dilute an ETG test. However, you will have to drink a large amount of water for the dilution process.
reducing the concentration of a chemical
magnesium sulphate, calcium chloride and ferric chloride are added to provided optimum environment and phosphate buffer is added to slow down the rate of death of microbes.
yes, u can test this by putting the chalk in water
you'll need a water test kit or dip stick test.

For pnematic test you have to use Air as a media but In case of hydrotes you can use water as media.

It's to see if you have VD.
They certainly can--they use an adulteration test.
Best way is to send it to a lab that conducts engine oil analysis. Make sure you ask for fuel dilution test as well as a Karl Fisher test. This is a guarantee way to know.
media used for oxidase test is non selective media
Serial dilution technique
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 At 5-minute intervas, samples are withdrawn from each dilution and used to inoculate a growth medium, which is incubated for two or more days and then examined the growth.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.
I drank a 32oz bottle of rescue ice and 16oz of water before my test, peed a bunch of times, then did the test. Worked great. No dilution, no problems. Recommend calling the number on the bottle and getting advice if you have time.
1. dilution error 2.blame the test sample 3.poor maintenance of bottles(cleaning)
No ,as there are natural sugars in fruit,which may affect the accuracy of a glucose blood test.
