# hypochlorous acid ka

The Ka of hypochlorous acid (HCIO) is 3.0 x 10-8 at 25 degrees C. What is the % ionisation of hypochlorous acid in a 0.015 M aqueous solution of HCIO at 25 degrees C? The Ka of hypochlorous acid (HClO) is 3.0 × 10-8 at 25°C. Hypochlorous acid is a weak acid (pKa of about 7.5), meaning it dissociates slightly into hydrogen and hypochlorite ions as noted in equation: : HOCl ⇌ H+ + OCl- Between a pH of 6.5 and 8.5 this dissociation is incomplete and both HOCl and OCl- species are present to some extent. Acid: Formula: Conjugate Base: K a: Perchloric : HClO 4 : ClO 4- Very large : Hydriodic : HI : I- Very large : Hydrobromic : HBr : Br- Very large : Hydrochloric : HCl : Cl- Very large : Nitric : HNO 3 : NO 3- Very large : Sulfuric : H 2 SO 4 : HSO 4- Very large : Hydronium ion : H 3 O + H 2 O : 1.0 : Iodic : HIO 3 : IO 3- … Hydrocyanic acid. Boric acid. H 3 BO 3. 5.8 * 10-10. Problem: Hypochlorous acid, HClO, is a weak acid. 3. The Ka values of acetic acid, hypochlorous acid and formic acid are 1.74 × 10^-5, 3.0 × 10^-8 and 1.8 × 10^-4 respectively. Calculate the pH of a 0.0385-M hypochlorous acid solution? NH 4 + NH 3. HCN. Acid with values less than one are considered weak. Click hereto get an answer to your question ️ The ionisation constant of an acid, Ka is the measure of strength of an 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? Please show ALL working CN-Cyanide ion. ClO-Hypochlorite ion. 5.8 * 10-10. Ammonia. ... Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Ammonium ion. Hypochlorous acid. 6.2 * 10-10. The magnitude of the equilibrium constant for an ionization reaction can be used to determine the relative strengths of acids and bases. For example, the general equation for the ionization of a weak acid in water, where HA is the parent acid and A− is its conjugate base, is as follows: HClO. Which of the following orders of pH of 0.1 mol dm^-3 solutions of these acids is correct?
