What happens when SO2 is passed through bromine water?
When bromine water reacts with SO2, it oxidises it to sulphuric acid and itself gets reduced to HBr.
Does H2S Decolourise bromine water?
Br2 oxidises H2S to S. In the reaction, brown colour of the Br2 water is decolourised but milkiness due to colloidal sulphur appears.
What liberates SO2 with Dil H2SO4?
Na2SO3.
Which of the following salt would give SO2 with hot and dilute h2 S o4 and also Decolourises Br2 water?
Na2SO3 N a 2 S O 3 reacts with hot and diluted H2SO4 H 2 S O 4 to give SO2 S O 2 gas which decolourises bromine water .
When Colourless gas is passed through bromine water only Decolourisation takes place the gas is?
sulphur dioxide gas
when colourless gas is passes through bromine water, only decolourisation takes place. the gas is. Dear, that gas is SO2( sulphur dioxide gas), This gas has a great reducing property that it can reduces the coloured solution in to halides.
How do you make bromine from bromine water?
Label the bottle “bromine water” or “Br 2 (aq).” Dissolve the sodium bromine in the hydrochloric acid, mixing the compounds in a flask or beaker. Pour the mixture into the glass bottle. Add the bleach to the mixture in the bottle.
Which of the following releases SO2 gas?
Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur.
When CU is heated with conc h2so4 it produces?
When copper is heated with concentrated sulphuric acid. Concentrated sulphuric acid is an oxidising agent . Complete answer: When copper reacts with concentrated sulphuric acid sulphur dioxide is produced by the reduction of \[{H_2}S{O_4}\].
Which of the following of side will form a salt with dilute sulphuric acid?
The formation of oxides includes the formation of a chemical compound with one or more oxygen atoms. For example- It reacts with dilute sulphuric acid to produce a sodium sulphate solution.
What Colour is bromine water?
orange
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.

How do you make bromine water?
Bromine water is a yellow mixture solution with high oxidizing property, prepared by dissolving diatomic bromine (Br 2) in water (H 2 O). Bromine water solution can be prepared in the chemistry lab by direct mixing of fumes of bromine and water.
What is the colour of bromine water when mixed with alkene?
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.
What compound decolourize bromine water?
What compound decolourizes bromine water? Unsaturated hydrocarbons such as alkenes and alkynes will decolourize bromine water. What happens when bromine water is added to hexane?
