What is the difference between sodium hypochlorite and bleach?
The difference between sodium hypochlorite and bleach is in the consistency of the substance. Sodium hypochlorite is a powder that can be mixed with water to create bleach. Bleach, on the other hand, is liquid and is simply the finished product that is the result of combining powdered sodium hypochlorite and water.
What is the percent of sodium hypochlorite in the bleach sample?
7.4\%
The label of a typical liquid bleach bottle (Figure 1) cites the concentration of its active ingredient, sodium hypochlorite (NaOCl), as being 7.4\%. A 100.0-g sample of bleach would therefore contain 7.4 g of NaOCl.
What is the difference between calcium hypochlorite and sodium hypochlorite?
The key difference between calcium hypochlorite and sodium hypochlorite is that calcium hypochlorite contains two hypochlorite anions associated with one calcium cation whereas sodium hypochlorite contains one hypochlorite anion associated with one sodium cation.
What is 5 sodium hypochlorite solution?
Sodium hypochlorite is a clear, slightly yellowish solution with a characteristic odor. Sodium hypochlorite has a relative density of is 1,1 (5,5\% watery solution). As a bleaching agent for domestic use it usually contains 5\% sodium hypochlorite (with a pH of around 11, it is irritating).
Is all bleach sodium hypochlorite?
Sodium hypochlorite is a white powder made up of chlorine and sodium hydroxide. When this powder solution is combined with water it creates the solution that is known as bleach. Oftentimes, sodium hypochlorite is just referred to as bleach, as liquid bleach is the most common use of sodium hypochlorite.
Is hypochlorite and sodium hypochlorite the same?
Sodium hypochlorite Sodium hypochlorite is chlorine gas dissolved in sodium hydroxide. This is essentially household bleach. Sodium hypochlorite is a disinfectant that is liquid at room temperature and can be dosed with chemical feed pumps.
What is the active ingredient you will be analyzing in the bleach sample?
sodium hypochlorite
In this experiment, the amount of the active ingredient, sodium hypochlorite (NaClO), in household Bleach will be determined. The oxidizing action of the hypochlorite ion, ClO-, kills germs and also decolorizes many stains and dyes.
How is the strength of sodium hypochlorite determined?
Add 2ml of sodium hypochlorite solution and mix well. Measure this solution with chlorine comparator. With this method, the units in mg/liter correspond to the concentration of the disinfectant produced. (For example, if the solution is 0.5 mg/liter, then the sodium hypochlorite solution is 0.5\%.)
Why is calcium hypochlorite more stable than sodium hypochlorite?
This compound is relatively stable and has greater available chlorine than sodium hypochlorite. It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air….Calcium hypochlorite.

Why is calcium hypochlorite preferred to sodium hypochlorite?
Calcium hypochlorite is more stable than sodium hypochlorite, and contains a higher chlorine concentration (30-75\%). Like sodium hypochlorite, calcium hypochlorite also increases water pH, so it is advised to acidify the water during the disinfection process.
Does sodium hypochlorite bleach?
Sodium hypochlorite is most often encountered as a pale greenish-yellow dilute solution referred to as liquid bleach, which is a household chemical widely used (since the 18th century) as a disinfectant or a bleaching agent. Sodium hypochlorite is the oldest and still most important chlorine-based bleach.
What is the concentration of sodium hypochlorite for disinfection?
Sodium hypochlorite: concentration and use: Recommended dilution 1:100 dilution of 5\% sodium hypochlorite is the usual recommendation. Use 1 part bleach to 99 parts cold tap water (1:100 dilution) for disinfection of surfaces.
What is the chemical formula for sodium hypochlorite bleach?
It is usually called bleach, because it is the active ingredient in bleach. The chemical formula is NaClO and consists of one atom of sodium (Na), one atom of chlorine (Cl) and one atom of oxygen (O). Will sodium hypochlorite kill weeds? Sodium hypochlorite, also called bleach, has an average pH of 11.
How much sodium is in Clorox disinfecting bleach?
The new Clorox ® Disinfecting Bleach formula contains 7.5\% sodium hypochlorite, compared to 6.0\% in the previous formulation. Concentrating our formula allows us to make smaller, more easily poured bottles, reduces plastic packaging and cuts down on water waste in manufacturing.
What is NaClO used for in Bleach?
NaClO Uses (Sodium hypochlorite) It is used as a key ingredient in laundry bleach. It is used as a bleaching agent. It is used in textile industries.
Does sodium hypochlorite change the pH of water?
No, because when the sodium hypochlorite solution is added to water, the water decreases the pH and the sodium hypochlorite becomes more active. The chemistry behind this is: the pH scale is from 0 to 14.
