Is the DNA test result positive or negative?
The DNA test result is positive.
Will methionine give lead acetate test?
Lead acetate test is used to detect the presence of sulfur-containing amino acids like cysteine and homocysteine, not methionine. Methionine does not give a positive result in the lead acetate test.
What color is positive test result for glucose?
the color of a positive test results is bright green
What is the positive result for sakaguchi test?
A positive result for the Sakaguchi test is the formation of a white or yellow precipitate in the presence of arginine or histidine in the test sample. This precipitate forms when ninhydrin (reagent used in the test) reacts with the guanidine group of arginine or the imidazole group of histidine.
Will methanol give a positive result in iodoform test?
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
What is the reduced sulfur test?
The reduced sulfur test is a method used to detect the presence of reduced sulfur compounds, such as hydrogen sulfide, in water or soil samples. It typically involves adding a reagent, such as lead acetate, that reacts with the reduced sulfur compounds to produce a color change indicating their presence. This test is important in environmental monitoring and assessment of water quality.
Is the DNA test result positive or negative?
The DNA test result is positive.
What is the positive result for reduced sulfur test?
I assume you mean the reaction between sulphuric acid and halide salts? Sulphur in H2SO4 has an oxidation state of +6 With Sodium Chloride (or any chloride salt): H2SO4 + 2NaCl → Na2SO4 + 2HCl This is a displacement reaction and nothing will be seen as sodium sulphate and hydrochloric acid remain in solution. With Sodium Bromide, the reaction is more vigorous and the S in H2SO4 is reduced. It becomes SO2. This is a colourless gas with a choking odour. Also HCl fumes may be given off because the reaction mixture is hot. With Sodium Iodide, more reduction happens. This is because Iodide is a strong reducing agent. SO2 becomes reduced to Suphur powder (yellow) and this can become further reduced to H2S which gives the smell of rotten eggs.
Methionine give a positive sulfur test?
yes
Why methionine gives a negative result for lead acetate test?
Methionine gives a negative result in the lead acetate test because it does not contain sulfhydryl (-SH) groups or any functional groups that can form lead sulfide (PbS), the black precipitate indicative of a positive test. The lead acetate test is specifically designed to detect the presence of compounds with sulfur, such as cysteine or cystine, which react with lead acetate to produce a visible precipitate. Since methionine lacks these reactive sulfur groups, it does not yield a positive result in this test.
Is the crystal violet test result positive or negative?
The crystal violet test result is positive.
Have you received a positive hCG test strip result"?
"Did you get a positive hCG test strip result?"
Will methionine give lead acetate test?
Lead acetate test is used to detect the presence of sulfur-containing amino acids like cysteine and homocysteine, not methionine. Methionine does not give a positive result in the lead acetate test.
Did gelatin give positive result with xanthoprotic test?
yes,it give positive test
Will a pregnancy test show positive if I miscarried?
A pregnancy test can show a positive result if you have miscarried. There is still enough hormone in your body to produce a positive result.
What is the positive result for molisch test?
all carbohydrates show positive result to Molisch test. this is because Molisch test is used to distinguish carbohydrates from other organic compound.
What dosage of Vyvanse will result in positive amphetamine result?
Any amount of Vyvanse could result in a positive amphetamine test.
