What happens when sodium bromide reacts with concentrated sulphuric acid?

NaBr NaBr + H2SO4 → NaHSO4 + HBr Not redox 2HBr + H2SO4 → Br2 + SO2 + 2H2O Redox The bromide ion in hydrogen bromide is a better reducing agent than chloride ions and reduces the oxidation number of sulfur in sulfuric acid from +6 to +4 in SO2.

What happens when sodium chloride reacts with concentrated sulphuric acid?

Sulphuric acid reacts with sodium chloride in the following way:2NaCl + H2SO4 → 2HCl + Na2SO4.

Does sulfuric acid react with sodium bromide?

1. The reaction between NaBr and H2SO4 is an acid-base reaction. Bromide ion, which results from dissociation of NaBr in water, reacts with sulfuric acid to capture one of its acidic protons. Equilibrium in acid-base reactions favors formation of the weaker acid (HBr) and the weaker base (bisulfate ion).

When concentrated sulfuric acid reacts with sodium iodide The products include?

17 When concentrated sulfuric acid reacts with sodium iodide the products include sulfur, iodine, hydrogen sulfide and sulfur dioxide.

What happens when NAI is heated with conc sulphuric acid?

(3) Sodium iodide With hot conc. sulfuric acid, the iodide ion in solid salts acts as an even stronger reducing agent than bromide, and the sulfuric acid is reduced to hydrogen sulfide gas and the iodide ion oxidised to free iodine.

What forms when sodium reacts with sulphuric acid?

When sodium hydroxide react with sulphuric acid they form Sodium sulphate and water.

When solid sodium iodide reacts with concentrated sulfuric acid the products include NaHSO4?

17 When solid sodium iodide reacts with concentrated sulfuric acid, the products include NaHSO4, H2S, SO2 and S. 18 A test-tube of HBr(g) and a test-tube of HI(g) are heated to the same temperature.

When concentrated sulfuric acid reacts with sodium iodide The products include sulfur iodine hydrogen sulfide and sulfur dioxide which statement is correct?

a reduction reaction
20 When concentrated sulfuric acid reacts with sodium iodide the products include sulfur, iodine, hydrogen sulfide and sulfur dioxide. Which statement is correct? A Hydrogen sulfide is the product of a reduction reaction.

When NaBr is heated with conc H2SO4 Br2 is produced but when NaCl is heated with conc H2SO4 HCl is produced why?

In case of NaBr, Br- acts as reducing agent fr H2SO4 and the sulphuric acid is reduced to sulphr ioxide by bromide ion which itself gets oxideised to give bromine free molecule.

When bromide is heated with conc H2SO4 the gas liberated is *?

NO2. Hint: KBr is an alkali metal halide. When it reacts with concentrated acid, we expect the halide to be liberated. Thus, the reddish-brown coloured gas we can see is of bromine.

Which gas is evolved when dilute sulphuric acid is added to sodium sulphide?

Sulfur dioxide gas will produce when dilute sulfuric acid is treated with sodium sulphite.
