which one of the following gives h2o2 on treatment with dilute acid?

The oxide that gives H2O2 on treatment with a dilute acid is Na2O2. Only true peroxides which have -O-O- bond give hydrogen peroxide with dilute acids.

Cleaning and disinfecting with Hydrogen Peroxide (H202) H202 is the perfect solution for sterilising fish tanks, pipework, glass and plastic. Unlike bleach, H202 will turn into harmless water and oxygen after 24 hours in contact with water. It is therefore the perfect solution for use in the aquarium environment.

Hydrogen peroxide (H2O2) is a clear liquid which is slightly thicker and denser than water but mixes very well with water. Hydrogen peroxide (3% solution) is frequently used for disinfecting and cleaning. It has a faint odor and is generally a noncombustible liquid.

All Brønsted acids can act as oxidizing agents, because the acidic proton can be reduced to hydrogen gas. Some acids contain other structures that act as stronger oxidizing agents than hydrogen ion. Generally, they contain oxygen in the anionic structure.

How to use hydrogen peroxide to kill viruses. The typical 3% hydrogen peroxide concentration found in stores can be used as a disinfectant, or you can dilute it to a 0.5% concentration, which still has some effectiveness, using a mixture of 2.5 parts water and 0.5 parts 3% hydrogen peroxide.

When hydrogen peroxide is added to potassium iodide in neutral solution, the potassium iodide acts as a catalyst in the decomposition of hydrogen peroxide into water and oxygen. Since the iodide ion is not consumed by the reaction, it is classed as a catalyst.

The major difference between a dilute acid and a weak acid is that a dilute acid is a strong acid which has been deconcentrated by adding water and increasing its pH value from nearly 1.5 to 4 or 4.5 and a weak acid is basically having pH greater than or equal to 4 even in its original solution .

The hydrogen oxalate ion (HC2O4) is amphoteric. Write a balanced chemical equation showing how it acts as an acid toward water and another equation showing how it acts as a base toward water.

Hydrogen peroxide, in proper dilution, is very effective and safe in septic tank cleaning. In its pure form, it can be detrimental for the septic tank and the surrounding environment. When you use hydrogen peroxide, septic odors will be eliminated. It is also less expensive.

Dilute sulfuric acid contains water. The ions present in this mixture are H + and OH - (from the water) and H + and SO 4 2- from the sulfuric acid. The H + ions are attracted to the cathode and the two negative ions are attracted to the anode but it is the OH - ion which loses electrons.

Hydrogen peroxide is both an oxidizing agent and reducing agent.

Over-the-counter mouthwash products will contain 1.5%-3% hydrogen peroxide. The recommended at-home dilution for a hydrogen peroxide mouthwash is half water, half 3% H2O2 rinsing for one minute up to four times daily.

Although it is insoluble in water, it is soluble to varying degrees in dilute hydrochloric-acid solutions, such as those in the stomach.

A solution of 0.8 mol/dm 3 hydrochloric acid has a pH of 0.1. Predict its pH when it is diluted to 0.08 mol/dm 3. The hydrogen ion concentration decreases by a factor of 10, so the pH increases by 1 from 0.1 to 1.1.

Hydrogen peroxide rinse is a mild antiseptic used in the mouth to help relieve minor mouth irritation (e.g., due to canker/cold sores, gingivitis, dentures, orthodontic appliances). It works by releasing oxygen when it is applied to the affected area.

Reaction between Sodium thiosulphate and Hydrochloric Acid Sodium thiosulphate reacts with dilute acid to produce sulphur dioxide, sulphur and water. Sulphur dioxide is a soluble gas and dissolves completely in aqueous solution.
