Hydrochioric acid's ionization will also produce chloride anions, Cl−. This means that the chemical equation that describes the ionization of hydrochloric acid will look like this. HCl(aq) +H2O(l) → H3O+ (aq) + Cl− (aq) Notice that every mole of hydrochloric acid that ionizes produces 1 mole of hydronium cations and 1 mole of chloride ...
1. Hydrochloric Acid (HCl) Hydrochloric acid, also known as muriatic acid, is a chemical compound with the formula HCl. This compound is a colourless, inorganic acid. Hydrochloric acid is known to have a very pungent odour. It is also known to be highly acidic and has the ability to attack and cause damage to the skin.
In general chemistry, i.e. in aqueous media, we define hydronium, H3O+ to have an acid dissociation constant of 1, or a pKa of 0. HCl, relative to this reference, has a pKa of −7, or a Ka of 107. Clearly, 107 >> 1, so HCl is a very strong acid. On the other hand, something like acetic acid, HC2H3O2, is a weak acid, because it has a Ka <1, or ...
Answer link. "HCl" (hydrochloric acid) is a strong acid. Why "HCl" is an acid can be explained on basis of many theories, like Arrhenius theory, Bronsted-Lowry acid base theory, and Lewis acid-base theory. According to Arrhenius theory, a compound which when dissolved in water dissociates and furnishes "H"^ (+) ions is an Arrhenius acid.
HCl is a strong acid, while HF is a weak acid. Acid strength refers to how much an acid ionizes when dissolved in water. In Arrhenius acid-base theory, an acid is a substance which dissolves in water to release one or more H^+ ions. A strong acid ionizes completely when dissolved in water. For example, when dissolved in water, every single HCl molecule separates into H^+ and Cl^-. A weak acid ...
Explanation: Hydrochloric acid is a strong acid and it is considered to completely dissociate in water under the following equation: 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 ...
Enthalpy of neutralization is the heat evolved when one gram equivalent of the acid is completely neutralized by a base in dilute solution. The chemical reaction is given below. H+ + OH– → H2O + 13.7 kcal. H+(aq) + Cl–(aq) + Na+(aq) + OH–(aq) → Na+(aq) + Cl–(aq) + H2O + 13.7 kcal. 13.7 kcal of heat is liberated out and is the heat ...
The protonolysis reaction lies strongly to the right. As an acid, hydrochloric acid undergoes protonolysis in water as shown: HCl(aq) + H_2O(l) rightleftharpoons H_3O^+(aq) + Cl^(-)(aq) This equilibrium lies strongly, almost quantitatively to the right, and it is the position of this equilibrium that justifies our designation of HCl as a strong acid.
To calculate the pH of HCl you need to know the concentration expressed in molarity (mol HCl/L solution). You will use the following equation to find the pH. pH = -log[H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl ...
