read books to find out :P
there isn't really a difference because they're just different ways of saying them example: 30 minute test/you have 30 minutes to take the test
what would happen if scientists were testing to see if a substance was safe to drink and used phenolphthalein as an indicator and what would happen if the test was done using methyl orange
The methyl red test is read immediately because fermentation occurs within a short time to produce an acid. Conversely, because oxidation requires more time, the Voges-Proskauer test is read after about an hour.
After 15 minutes Between 1 and 2 minutes
After 15 minutes Between 1 and 2 minutes
no
You use methyl red as a ph indicator for for the MRVP test.
no no
no it is positive
can methyl-dopa make you test positive for barbituates
after 30 minutes from the administration..
Staphylococcus epidermidis indole test - negative methyl red - negative voges proskauer test - positive citrate test - no idea
A microorganism does not require inoculation, therefore it is given an uninoculated test. In this test, DNA binds to methyl green.
The test of ethyl and methyl alcohol may provide some evidence, but it is not necessarily conclusive. Further analysis and testing could be needed to confirm the presence and differentiate between the two types of alcohol definitively.
