Web1 Answer. Sorted by: 2. A square wave is a waveform in which the amplitude alternates between A and − A (being A > 0 ). The RMS value of a waveform is calculated as. f r m s = 1 T ∫ 0 T [ f ( t)] 2 d t. As in the case of a square waveform, either f ( t) = A or f ( t) = − A, then [ f ( t)] 2 = A 2 for any value of t. my nceeWebAmino acid pK a values. pK a values of amino acid side chains play an important role in defining the pH-dependent characteristics of a protein. The pH-dependence of the … old people\u0027s teethNitric acid, with a pK value of ca. -1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. At lower pH values it behaves as a weak acid. pK a values for strong acids have been estimated by theoretical means. For example, the pK a value of aqueous HCl has been estimated as −9.3. … See more In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted $${\displaystyle K_{a}}$$) is a quantitative measure of the strength of an acid in solution.
