It means that it tests positive for either aldehyde, alkene, or phenol functional groups.
A positive Molisch's test result indicates the presence of carbohydrates.
The Presence-Absence (P-A) test is a presumptive detection for coliforms.
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
It depends on what that pregnancy test uses to indicate pregnancy. Read the directions carefully to see what they use to indicate a positive or negative pregnancy test.
Yes it does. This is a general test for unsaturation.
Hexane and benzene do not react in the ignition test. Only acetylene does. Acetylene has a triple bond if equivalent amount of KMnO4 is used. The equation is HCCH + KMnO4 -> HC (OH) = CH(OH).
The formula for potassium permanganate is KMnO4
Yellow, which means bacteria is able to produce acids from mannitol fermentation
Yes, the biuret test will indicate the presence of peptides. If it turns violet, it is a positive result.
Signs of pregnancy are absent period and positive pregnancy test. If you think you're pregnant, take a pregnancy test.
If your pregnancy test is positive then most likely you are. You would be more likely to get a false negative rather than a false positive. If you are unsure, you can request a beta HCG test from your doctor. This will measure the HCG hormone in your blood system which is an indicator of pregnancy. The pregnancy test is positive and you haven't had a period in two months. I see nothing to indicate that this is a 'phantom' pregnancy other than maybe wishful thinking. I've been told that the home test kits may give a false negative, but that they never indicate a false positive.
