Strong acids are H3O plus, HNO3, H2SO4, HCl, and HBr. Negligible acids are HS minus and OH minus. Stron bases are O negative 2, S negative 2. Negligible bases are NO3 minus, HSO4 minus, Cl minus, and Br minus. The relative strengths of some common acids and their conjugate bases are shown graphically in Figure \(\PageIndex{1}\). Find the acid and base strengths of various chemical species, such as perchloric acid, hydroiodic acid, hydrobromic acid, hydrochloric acid, sulfuric acid, nitric acid, and more. The table is sorted by acid base name and formula, and includes the acid base strength in molarity. Ka: Name: Formula: Formula: Name: Strength of Base: Strongest: Large: Perchloric acid: HClO 4: ClO 4-Perchlorate ion: Weakest 3.2 * 10 9: Hydroiodic acid: HI: I-Iodide 1.0 * 10 9: Hydrobromic acid: HBr: Br-Bromide 1.3 * 10 6: Hydrochloric acid: HCl: Cl-Chloride 1.0 * 10 3: Sulfuric acid: H 2 SO 4: HSO 4-Hydrogen sulfate ion 2.4 * 10 1: Nitric ... H Cl(aq) + H 2O(l) → H 3O+(aq) +Cl−(aq) The equilibrium constant Ka is written as: Ka = [H 3O+][Cl−] H Cl. Since the acid dissociates completely, the concentration of products ( [H 3O+] and [Cl−]) is very large and the concentration of the reactant ( [H Cl]) is very small. Thomas Barwick/Getty Images By Todd Helmenstine Updated on February 03, 2020 K a is the equilibrium constant for the dissociation reaction of a weak acid. A weak acid is one that only partially dissociates in water or an aqueous solution. The value of K a is used to calculate the pH of weak acids. Hidrogen klorida (HCl) adalah asam monoprotik, yang berarti bahwa ia dapat terdisosiasi (terionisasi) melepaskan satu H + (sebuah proton tunggal) hanya sekali. Dalam larutan asam klorida, H + ini bergabung dengan molekul air membentuk ion hidronium, H: [22] [23] HCl + H → H + Cl. Ion lain yang terbentuk adalah ion klorida, Cl −. The Ka of HCl is 1.3 x 10^6. This is constituted as a large Ka. Hydrochloric acid is a strong acid and has complete dissociation in aqueous solution. Therefore, its Ka approaches infinity. The acid dissociation constant, or Ka, is a way of ranking the strength of acids. Acids with lower Ka values are called weak acids. Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans. Ka can be calculated as the ratio of the product of the concentrations of the products to that of the reactant, that is, Ka = [H 3O+][Cl−] [H Cl] Since H Cl is a strong acid, the value of Ka turns out to be very large, that is, Ka = 107 1 = 107 (approx.) The value of pKa is given by. pKa = −logK a. pKa = −(log107) E1: Acid Dissociation Constants at 25°C. * Measured at 20°C, not 25°C. ‡ Measured at 18°C, not 25°C. Source of data: CRC Handbook of Chemistry and Physics, 84th Edition (2004). Jika 10 mL larutan asam format (HCOOH) 0,1 M memiliki pH sama dengan HCl 0,02 M, maka Ka asam format adalah ... A. 2 x 10^-2 B. 4 x 10^-3 C. 2 x 10^-3 D. 4 x 10^-4 E. 4 x 10^-5 The Ka is often a very, very small number or a very, very large one. In the case of HCl in water, the Ka is about 1 x 10 8. Dealing with exponents can be cumbersome. In order to simplify comparisons, the equilibrium constant is expressed logarithmically. pKa = -logKa. The pKa for HCl transferring a proton to water is -8.
