With iodide ions They are oxidised to iodine by the concentrated sulphuric acid. and all the way to hydrogen sulphide (sulphur oxidation state = -2)..
Also know, what happens when sodium chloride reacts with concentrated Sulphuric acid?
Sodium chloride react with sulfuric acid to produce sodium sulfate and hydrogen chloride. Sulfuric acid - concentrated solution. The reaction takes place in a boiling solution.
One may also ask, does iodine react with acids? Reactions with acids Iodine reacts with hot concentrated nitric acid to form iodic acid. The iodic acid crystallizes out on cooling.
People also ask, can h2so4 acts as a reducing agent?
It is always an oxidizing agent. In H2SO4 sulphur is in +6 oxidation state. As sulphur is already in it's maximum possible oxidation state in H2SO4, further loss of electrons is not possible. So it can't act as a reducing agent.
What does h2so4 test for?
Test for sulfuric acid (and soluble sulfates) This is to prevent precipitation of other insoluble barium compounds such as BaCO3 or BaSO3. Secondly, add Ba(NO3)2 (aq). If sulfuric acid or a sulfate is present a white precipitate will be immediately observed.

What happens when you mix salt and sulfuric acid?
When sodium chloride is mixed with sulfuric acid, there is a chemical reaction and hydrogen chloride and sodium hydrogen sulfate are formed. a) Sodium is gaining an electron to form sodium metal.Why sodium chloride does not react with hydrochloric acid?
Students usually believe that sodium chloride don't react with hydrochloric acid because it is a neutral salt and create no change in the solution. If another solution that doesn't react with the orginal solution is added, the total volume of solvent is increased, and thus its concentration is decreased.Does NaCl react with acid?
Sodium Chloride won't react with Hydrochloric Acid to form a new a chemical compound. But the solubility of NaCl will decrease due to the common ion effect. Sodium Chloride won't react with Hydrochloric Acid to form a new a chemical compound. But the solubility of NaCl will decrease due to the common ion effect.Does NaCl react with NaOH?
NaCl & NaOH both are containing same cation (Na+). But here the cation (Na+) is same between NaCl & NaOH. NaCl is a salt that rapidly dissociate in water. NaOH is a strong base that will also completely dissociate. So mixing the two solutions will create no precipitate, or otherwise have no observable reaction.What does sodium chloride react with?
The most common salt, sodium chloride (NaCl), is a product of the reaction between hydrochloric acid (HCl) and the base sodium hydroxide (NaOH). In this reaction, positively charged hydrogen ions (H+) from the acid are attracted to negatively charged hydroxyl ions (OH-) from the base. These ions combine and form water.Will sodium bicarbonate and hydrochloric acid undergo a chemical reaction?
“Mixing baking soda, or NaHCO3, with hydrochloric acid, or HCl, results in table salt, NaCl, as well as water, H2O, and carbon dioxide, CO2. These experiments can also demonstrate stoichiometry, which deals with the reactants and products in chemical reactions.”When sulfuric acid is added to solid sodium chloride and the mixture is heated?
When sulfuric acid is added to solid sodium chloride and the mixture is heated, hydrogen chloride gas is generated, leaving a solid residue of sodium sulfate.How do you make Sulphuric acid?
Sulfuric acid is produced from sulfur, oxygen and water via the contact process. In the first step, sulfur is burned to produce sulfur dioxide. This is then oxidised to sulfur trioxide using oxygen in the presence of a vanadium(V) oxide catalyst.Is KMnO4 a reducing agent?
The oxalic acid acts as a reducing agent, and the KMnO4 acts as an oxidizing agent, KMnO4 acts as an indicator of where the permanganate ions are a deep purple colour.Is HCl a reducing agent?
H+ in HCl is the reactantreduced, and HCl is the oxidizing agent. HCl is an oxidizing compound, because 2H+ + 2e- --> H2 ( St. E.P. = 0.00 V) and Chloride ions are a very weak reducing agent (2Cl- --> Cl2 + 2e- at St.Is nitric acid a reducing agent?
In nitric acid (HNO3), nitrogen is in its maximum oxidation state of +5, and it cannot be oxidised further to any higher state. So, it cannot act as a reducing agent. In any oxidation-reduction reaction, the oxidising agent gets reduced to a lower state, and the reducing agent gets oxidised to a higher state.Why is nitric acid a strong oxidizing agent?
HNO3 is an oxidizing AGENT because the N can be readily reduced. Nitric acid is an active oxidizing agent. Nitric acid is a strong oxidizing agent and the nascent oxygen produced on decomposition oxidizes hydrogen to water. This is the purpose why it does not release hydrogen when operated with metals.Why is sulphurous acid a reducing agent?
Sulfurous acid acts as a good reducing agent because it has the ability to take up oxygen from the air and other substances that are rich in oxygen. Here S has tendency to loose more electron so it acts as reducing agent.Why Sulphuric acid is a dehydrating agent?
Concentrated Sulphuric Acid is used as a drying and Dehydrating agent because it has a strong affinity for water and thus it absorbs water quickly.How is h2so4 an oxidising agent?
It will dissociates into SO3 + H2O, thus will fulfill its desire. So sulphuric acid in concentrated forms gives nacent oxygen and forms sulphurous acid. This nacent oxygen act as oxidizing agent.Why Sulphuric acid is hygroscopic?
Concentrated sulfuric acid is very hygroscopic. Its affinity for water is so great that if you left a beaker half full with conc. H2SO4 for three weeks, its volume would greatly increase and it would become more dilute because it would have absorbed so much water vapour out of the air.Is sodium an oxidizing agent?
Sodium is an alkali metal and so very easily oxidized to form Na+. So no, it is not an oxidizing agent. In fact, elemental sodium is a very good reducing agent and is widely used in inorganic and organic chemistry.Is iodine acidic or basic?
Iodine is neither an acid NOR a base..Is Iodine a strong reducing agent?
The lost electrons will be gained by another species which will be reduced making iodide a good reducing agent. On the other hand, Iodine is not the strongest oxidizing agent and does not make other species lose electrons very easily compared to the oxidizing potential of chlorine, bromine or fluorine.
