Basicity of Acids: Basicity of acids is defined as the number of ionizable hydrogen atoms. Some examples are: HCl: basicity is 1 H2SO4 H3PO4 H3PO3orH2PO3H Answer and Explanation:1 CH3COOH Learn more about this topic: Organic Acid Definition, Properties & Examples ...
(The pKa of acetic acid is 4.76) How are Ka and Kb values of an acid and base used to determine the acidic or basic nature of their aqueous salt solution? Applying this process, determine if a salt solution of NH4ClO2 is acidic, basic, or neutral...
Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chemical formula...
Stick around, be anonymous, and learn the answers to “what is pH?”“what is pKa?” and “what is pI” without ignominy. A Crash Course on Logarithms The “p” in pH, pKa, and pI denotes the negative logarithm, to base 10, of the parameter in question. Logarithms transform a nonli...
Which of the following four compounds is the most acidic (i.e., has the lowest pKa value)? How can i know whether solution is acidic or not and then what type of acid? What is the OH- if the H+ is observed to be 6.5? Is it acidic, basic or neutral?
where HA is the acid and A- is the conjugate base. Ka = [A-][H3O+] / [HA][H2O] This is used to calculate pKa, the logarithmic constant: PKA = – log10 Ka The larger the pKa value, the smaller the dissociation of the acid and the weaker the acid. Strong acids have a pKa of...
The reducing power of DTT is affected by pH value, and it can only exert its reducing effect when the pH value is greater than 7. This is because only the deprotonated thiolate anion (-S–) is reactive, but thiol (-SH) is not; and the PKa of the thiol group is generally ~8.3. ...
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
Here, S is a solvent molecule, such as water or dimethyl sulfoxide (DMSO). For example, here is the dissociation of hydrochloric acid in water: HCl(aq) → H+(aq) + Cl-(aq) A strong acid hasa pKa valueless than -2. The pKa value of the acid depends on the solvent. For example,...
As a very weak base with a pKa of 8.2, benzotriazole exhibits more acidity than indazole, benzimidazole, and 1,2,3-triazoles. Its stability is enhanced by the fused benzene ring, which contributes to the stability of the conjugate base. ...
