Editor's note: The regular strength hydrogen peroxide (3-5 percent) is OK to ingest, but higher strengths (10 percent or more) can be toxic if swallowed.

Consequently, what does percent strength and hydrogen peroxide mean?

(Volume is also called “volume strength”.) Volume is the amount of oxygen that is contained in a given amount of peroxide. For example, 3% hydrogen peroxide is V10 or 10 volume, because it will release 10 times it's volume in oxygen. One pint of 3% hydrogen peroxide will release 10 pints of oxygen as it breaks down.

Secondly, what is the strongest hydrogen peroxide? "Food grade" hydrogen peroxide is 35%. Despite its name, "food grade" hydrogen peroxide should never be taken internally, unless it is extremely dilute. Higher concentrations of hydrogen peroxide, up to 90 percent, are used in industry.

Accordingly, what is volume strength of hydrogen peroxide?

Volume strength of H2O2 is the volume of O2 released on decomposition of one volume of H2O2 at STP. So, if H2O2 is labeled 10Vol decomposing 1L of that solution will give 10L of O2 and if decompose 1mL then give 10mL of O2.

What is the formula for volume strength?

?so we can say that 1 volume of H2O2 gives 20 volume of O2 at S.T.P. ??The volume of oxygen released at S.T.P. is used in concentration of hydrogen peroxide in solution==== volume strength/ percentage strength.

What is the strength of a solution?

The strength of a solution refers to the amount of solute or concentration of solute present in the container in which solute and solution are present.

What is the strength of 10 volume solution of hydrogen peroxide?

Therefore strength of H2O2 in 10 volume H2O2 solution = 30 gm/L = 3 % H2O2 solution.

Why is h2o2 a factor of 2?

Hence, 2e-s are exchanged per 2 moles of . Thus, the valency factor is 2/2 = 1. So, the valency factor of hydrogen peroxide for this reaction is ONE and not TWO! However in most of its oxidation/reduction reactions in acidic/basic media, the valency factor of is indeed 2.

What is the equivalent weight of hydrogen peroxide?

The equivalent weight of H2O2 is 34.01 g.

What is the percentage purity of hydrogen peroxide?


Percentage (%w/v): This is the weight of H2O2 per unit volume. This is more commonly used in our country. Generally 35% H2O2 and 50% H2O2 used in textile sector in our country. But 50% H2O2 is most widely used.

What does 20 volume h2o2 mean?

"20 volume", means 1 dm3 of peroxide solution produces 20 dm3 oxygen. 20 dm3 oxygen is 20 / 24.47 = 0.817 moles (at 298K and 1 atm) therefore, 1 dm3 of solution must contain 2 x 0.817 = 1.635 moles peroxide. so "20 volume" hydrogen peroxide is 1.635M. 1.

Is 30% hydrogen peroxide dangerous?

Many common substances, including iron and other transition metals, will catalyze the decomposition to product copious amounts of oxygen gas and heat. The 30% solution is a dangerous fire and explosion risk—do not heat. Dilute 3% and 6% hydrogen peroxide solutions are weak oxidizers and skin and eye irritants.

Is it safe to rinse your mouth with hydrogen peroxide?

Gargling hydrogen peroxide may be an effective way to sooth a sore throat, disinfect your mouth, and whiten your teeth. Just make sure you dilute it first, and try not to swallow any in the process. If you're hoping to whiten your teeth, try to gargle consistently for several months for the best results.

What is the highest percent of hydrogen peroxide you can buy?

Super high concentrations of hydrogen peroxide, like 50% and 70% and 90%, are used for some industrial purposes, and as rocket fuel. The higher the percentage of peroxide, the more dangerous it is, and the more special handling it takes.

What is the percentage of hydrogen peroxide used for cleaning?


Hydrogen peroxide, H2O2, is sold in concentrations of three to ten percent at most drug stores. The three percent solution works great for household cleaning and disinfecting.

Is hydrogen peroxide an acid or base?

Hydrogen peroxide is a weak acid, and it can form hydroperoxide or peroxide salts or derivatives of many metals.

What all can peroxide be used for?

Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/cold sores, gingivitis).

What is meant by 10 volume hydrogen peroxide?

10 Volume Hydrogen peroxide means that it will produce 10 times its volume in Oxygen. This is a fairly weak solution, which could likely be used to bleach hair.

How do you test the concentration of hydrogen peroxide?

The classical methods for measuring hydrogen peroxide concentration are :
  1. Direct measurement of the absorbance at 240nm of the H2O2 molecule.
  2. Through reaction of the peroxide with ferrous iron, monitored via a subsequent reaction with the dye xylenol orange and measurement of the absorbance of the solution at 550nm.

What does 100 volume hydrogen peroxide mean?


Hydrogen peroxide (H2O2) is water (H2O) with an “extra” oxygen atom. The term volume refers to the amount of oxygen gas that is released. One ounce of 100 volume peroxide will release 100 ounces of oxygen gas. The volume indicates the concentration of peroxide in the solution.

Why hydrogen peroxide is used for dressing of wounds and cuts?

Hydrogen peroxide has been used as an antiseptic since the 1920s because it kills bacteria cells by destroying their cell walls. With fewer electrons, bacteria cells' walls become damaged or even completely break apart. Unfortunately, hydrogen peroxide's oxidation also destroys healthy skin cells.

What is the volume strength of 1.5 N h2o2?

Volume strength refers to the number of volumes of oxygen gas evolved by one volume of H2O2. Now, 1.5 N of H2O2 will contain 1.5 equivalents of H2O2 per litre. 1.5 equivalents of H2O2 means 1.5/2 = 0.75 moles of H2O2. Now 0.75 moles of H2O2 form 0.75/2 moles of O2.
