Ammonium ion. 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: Problem: Hypochlorous acid, HClO, is a weak acid. Acid with values less than one are considered weak. HClO. ClO-Hypochlorite ion. HCN. Click hereto get an answer to your question ️ The ionisation constant of an acid, Ka is the measure of strength of an acid. Hydrocyanic acid. 6.2 * 10-10. 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. Ammonia. 5.8 * 10-10. 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. 3. 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- … Calculate the pH of a 0.0385-M hypochlorous acid solution? Which of the following orders of pH of 0.1 mol dm^-3 solutions of these acids is correct? The Ka of hypochlorous acid (HClO) is 3.0 × 10-8 at 25°C. Hypochlorous 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? The magnitude of the equilibrium constant for an ionization reaction can be used to determine the relative strengths of acids and bases. CN-Cyanide ion. NH 4 + NH 3. Boric acid. Please show ALL working 5.8 * 10-10. H 3 BO 3. ... Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. 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?
