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.

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.
Will decane give positive bromine test?
Positive Bromine tests are for unsaturated compounds that have double or triple bonds. Decane has a single bond, so the test will be negative.
What amino acid will yield a positive result with lead acetate test?
Cysteine will yield a positive result with the lead acetate test due to the formation of lead sulfide. Lead sulfide appears as a black precipitate when cysteine is present in the solution.
Will oxymetazoline hcl test positive on drug test?
Oxymetazoline HCl, a common ingredient in nasal decongestants, is unlikely to cause a positive result on a standard drug test. However, it's always important to inform the testing facility of any medications or substances you have consumed to ensure accurate results.
Does megestrol acetate test positive for THC?
No, megestrol acetate is a synthetic progestin hormone used in the treatment of certain medical conditions and weight loss. It is not known to cause a positive result in a drug test for THC (tetrahydrocannabinol), the psychoactive component of cannabis.
Positive result of reduced sulfur test?
A positive result in the reduced sulfur test indicates the presence of reduced sulfur compounds in the sample. These compounds can be produced by certain bacteria or by chemical reactions involving sulfur-containing molecules. The test usually involves a color change or the formation of a black precipitate to confirm the presence of reduced sulfur compounds.

Is the DNA test result positive or negative?
The DNA test result is positive.
Methionine give a positive sulfur test?
yes
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 of nitroprusside test?
RED
What dosage of Vyvanse will result in positive amphetamine result?
Any amount of Vyvanse could result in a positive amphetamine test.
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.
