What is the Ka for sodium hypochlorite?
(b) Calculate the pH of a 0.100 M NaOCl solution given sodium hypochlorite is completely ionized in water. is Ka = 6.6×10−4.
What is the Ka value of hypochlorous acid?
The value of Ka for hypochlorous acid (HOCl) is 2.8 x 10-8.
How do you calculate KB?
Solve the equation for Kb by dividing the Kw by the Ka. You then obtain the equation Kb = Kw / Ka. Put the values from the problem into the equation. For example, for the chloride ion, Kb = 1.0 x 10^-14 / 1.0 x 10^6.
What is the kb of CN?
Question: Kb for CN- = 2.0×10^ -5 Ka for NH4+ = 5.6×10^ -10 Calculate the pH of a 0.20 M solution of NH4Br.
What is NaClO used for?
Sodium hypochlorite, commonly known as bleach, is most frequently used as a disinfecting agent. It is a broad-spectrum disinfectant that is effective for the disinfection of viruses, bacteria, fungi, and mycobacterium.
What is the difference between sodium hypochlorite and bleach?
Simply put the difference between sodium hypochlorite vs bleach is the consistency. Sodium Hypochlorite on its own is the powder substance used to create liquid beach, and bleach is a liquid disinfectant and whitening agent made by combining sodium hypochlorite with water.
What is KA equal to?
The Ka expression is Ka = [H3O+][C2H3O2-] / [HC2H3O2]. The problem provided us with a few bits of information: that the acetic acid concentration is 0.9 M, and its hydronium ion concentration is 4 * 10^-3 M. Since the equation is in equilibrium, the H3O+ concentration is equal to the C2H3O2- concentration.
What is the kb of a strong base?
A large Kb value indicates the high level of dissociation of a strong base. A lower pKb value indicates a stronger base. pKa and pKb are related by the simple relation: pKa + pKb = 14.
Does higher KB mean stronger base?
The weaker the acid, the stronger the base. The stronger the base, the higher the Kb. The weaker the acid, the lower the Ka.
How much hypochlorite is in household bleach?
Household bleach is, in general, a solution containing 3–8% sodium hypochlorite, by weight, and 0.01–0.05% sodium hydroxide; the sodium hydroxide is used to slow the decomposition of sodium hypochlorite into sodium chloride and sodium chlorate.
What kind of solution is sodium hypochlorite?
Sodium hypochlorite (NaOCl) is a solution made from reacting chlorine with a sodium hydroxide solution. These two reactants are the major co-products from most chlor-alkali cells.
Which is better low or high concentration hypochlorite?
Low concentration hypochlorite solutions decompose slower than high concentration hypochlorite solutions. Fifteen weight percent sodium hypochlorite will decompose approximately 10 times faster than 5 wt% sodium hypochlorite at 25°C. The pH has a significant effect on the stability of sodium hypochlorite solutions.
What is the dot number for sodium hypochlorite?
DOT Number: UN 1791 Description and Use Sodium Hypochlorite is a clear, slightly yellow or green liquid with a strong Chlorine odor. It is usually mixed in water and used as a household cleaner, a disinfectant, and a bleaching agent. It is also used in water treatment and purification. Reasons for Citation
