What product forms the reaction between sodium and iodine?

Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine.

What does NaOH and i2 do?

When iodine and sodium hydroxide are used as the reagents a positive reaction gives iodoform, which is a solid at room temperature and tends to precipitate out of solution causing a distinctive cloudiness.

Does iodine disproportionate with NaOH?

A : Iodine can disproportionate in basic medium (NaOH).

Which is the byproduct of Haloform reaction?

The resulting products of the reaction are the carboxylate and the tribromomethane, which is the required haloform. This reaction was formerly used to industrially produce chloroform, bromoform and iodoform.

What is formed when chlorine reacts with sodium hydroxide?

sodium hydroxide react with chlorine to form bleaching powder, equation for reaction. Sodium hydroxide is not used in the production of bleaching powder.

What reacts with alkaline aqueous iodine?

All secondary alcohols give a positive result, as they are oxidised to ketones. And propan-2-ol is a secondary alcohol. So, all the compounds above i.e. butanone, Ethanal and propan-2-ol react with alkaline aqueous iodine to give a pale-yellow precipitate of tri-iodomethane.

What type of compounds give iodoform test?

Iodoform test is used to check the presence of carbonyl compounds with the structure R-CO-CH3 or alcohols with the structure R-CH(OH)-CH3 in a given unknown substance. The reaction of iodine, a base and a methyl ketone gives a yellow precipitate along with an “antiseptic” smell.

How will you separate iodine from a mixture of iodine?

Sublimation is the process to separate iodine from a mixture of iodine and common salt. Sublimation is the transition of a substance directly from solid to the gas phase, without passing through the liquid phase.

What happens when iodine reacts with sodium hydroxide?

The feedback you provide will help us show you more relevant content in the future. Iodine react with sodium hydroxide to produce sodium iodide, sodium iodate and water will form. I2 reacts with dilute NaOH to form NaI (iodide) and NaOI (hypo iodite)and with concentrated NaOH it gives NaI (iodide) and NaIO3 (iodate)….

What is the product formed when nitric acid reacts with iodine?

The acid formed from the reaction of nitric acid with iodine is HIO3. The acid formed from the reaction of nitric acid with sulfur is H2SO4. The acid formed from the reaction of nitric acid with phosphorus is H3PO4. The product from reaction of nitric acid with carbon is CO2.

What happens when you mix HNO3 and NaOH?

The HNO3 and NaOH combined and form a salt and water. The salt is the Sodium nitrate. You could also call this a double displacement reaction. Be careful when you count the number of hydrogen atoms! What is the reaction between hydrochloric acid and sodium hydroxide?

What happens when lead reacts with NaOH?

Therefore lead reacts with strong aqueous alkalis such as NaOH to produce hydrogen gas and sodium trihydroxoplumbate (II). Unlike more reactive amphoteric metals, such as aluminium, the above reaction is very slow… even with concentrated NaOH solutions. In addition, the trihydroxoplumbate (II) ion is unstable in hot aqueous solutions.
