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.Know More
The acid dissociation constant, or Ka, is a way of ranking the strength of acids. Acids with lower Ka values are called weak acids. These acids dissociate only partially. Examples of weak acids are acetic acid (vinegar), ascorbic acid (vitamin C) and formic acid.
Polyprotic acids can lose more than one proton. These acids have Ka values for the loss of each proton. In general, the Ka reduces as each successive proton is lost.Learn more about Chemistry
Each of the alkaline earth metals reacts with HCl, also known as hydrochloric acid, to form hydrogen gas and its corresponding metal chloride solution. The reaction becomes stronger the further down the group the element is on the periodic table.Full Answer >
Ka and Kb stand for acid dissociation constant and base dissociation constant. Simply put, Ka describes how acidic a solution is, and Kb describes how basic a solution is. Every solution has a value for both Ka and Kb.Full Answer >
Calculate the pH value from the Ka by using the Ka to find the concentrations, or molarity, of the products and reactants when an acid or base is in an aqueous solution. Calculate the pH by taking the -log of the concentration of the H3O.Full Answer >
The pKa can be derived by taking the negative logarithm of Ka so that pKa = minus log(Ka). Ka is known as the acid dissociation constant and is a measure of the strength of the acid. The pKa is the acid disassociation constant on a logarithmic scale, and acids with a pKa below minus 2 are considered strong acids.Full Answer >
