What is the Ka expression for HOCl?
What is the Ka expression for HOCl?
The value of Ka for hypochlorous acid (HOCl) is 2.8 x 10-8.
What is the pH of hypochlorous acid?
5.0 to pH 8.0
hypochlorous acid is presented from pH 5.0 to pH 8.0. Sodium hypochlorite (NaOCl) of the highest purity was prepared for this work.
How does hypochlorous acid react with water?
In water, hypochlorous acid occurs both as a chemical chlorine solution and as water. It is a colorless solution and its exact physical properties are variable and they depend on the concentration of the solution. Hypochlorous acid reacts with bases to form salts called hypochlorites.
What would be the products when the weak acid HClO reacts with water?
Problem: Hypochlorous acid, HClO, is a weak acid. The following is the equilibrium equation for its reaction with water:HClO (aq) + H2O (l) ⇌ H3O+ (aq) + ClO- (aq) Ka = 2.9 x 10-8What is the hydroxide ion concentration, [OH-], in a 1.98 M HClO solution?
Why HOCl is a weak acid?
Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO cannot be isolated from these solutions due to rapid equilibration with its precursor.
What is the Ka of NaOCl?
(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.
Is hypochlorous acid a weak acid?
Hypochlorous acid (HOCl). Formed from the activation of phagocytes through myeloperoxidase (MPO)-mediated peroxidation of Cl−using H2O2. Although a weak acid (pKa=7.5), HOCl is considered a strong oxidizing agent responsible for the killing action of phagocytes against a variety of pathogens.
Is hypochlorous acid unstable?
Hypochlorite is very unstable, but hypochlorous acid is stable and is highly microbicidal, active against bacteria, viruses, and fungi.
Why is hypochlorous acid a weak acid?
Is hypochlorous acid soluble in water?
Water
Hypochlorous acid/Soluble in
Why is HClO a weak acid?
These acids are the only ones that fully dissociate in water. All other acids are weak acids. Since HClO is not one of these seven, and there is no -OH group present as there is in bases, HClO is a weak acid. Another way to verify that this is an acid instead of a base is by looking at the ion it dissociates into.
Is hypochlorous acid volatile?
Only the hypochlorous acid fraction is volatile. The measured Henry’s Law constant for hypochlorous acid of 0.097 Pa m³ molindicates that volatilisation from surface water is not expected to be an important process.
Is hypochlorous acid a strong or weak acid?
Hypochlorous acid, HClO, is a weak acid. The following is the equilibrium equation for its reaction with water: What is the hydroxide ion concentration, [OH-], in a 1.98 M HClO solution?
What is the Ka of hypochlorous acid (HClO)?
The Ka of hypochlorous acid (HClO) is 3.0 × 10-8 at 25°C. Calculate the pH of a 0.0385-M hypochlorous acid solution? i got help with this problem, but i dont get where one of the numbers came from (3.4 x 10^-5)??? i tried making 3.0 x 10^-8 the x but i still dont get that number.
What is the value of [H3O+][OCL-]?
Hypochlorous acid, HOCl, is a weak acid in water. The Ka expression for HOCl is shown below: [H3O+][OCl-]/ [HOCl]= 3.2 X 10^-8.
What is the equilibrium equation for HClO + H2O + water?
Problem: Hypochlorous acid, HClO, is a weak acid. The following is the equilibrium equation for its reaction with water:HClO (aq) + H2O (l) ⇌ H3O+ (aq) + ClO- (aq) Ka = 2.9 x 10-8What is the hydroxide ion concentration, [OH-], in a 1.98 M HClO solution?
