Numerical value.8.617 333 262... x 10-5eV K-1. Standard uncertainty. What is KB in chemistry? Kb is thebase dissociation constant. The base dissociation constant is a measure of how completely a base dissociates into its component ions in water. Kb = [B+][OH-]/[BOH] pKb = -log ...
The value of Ka for acetylsalicylic acid (aspirin) is 3.00×10−4. What is the value of Kb for its conjugate base, C9H7O4−? Dissociation Constant: The acid dissociation comes into the picture when a solution contains a weak acid, and...
In chemistry, a chemical reaction is defined as the process in which two or more substances react with each other (also known as reactants) to produce one or more new substances (also known as products). These substances are known as compounds or chemical elements. In a chemical re...
pKb is the criterion used to estimate the alkalinity of the molecule, whereas Kb or base dissociation constant is the criterion used to estimate a base's strength. It tells us about how much a base dissociates in an aqueous solution.
Consider a saturated solution of Fe(OH)2 to which NaCN is added, and then write the solubility equilibrium for Fe(OH)2. Look up the relevant K value. What is the concentration of Ca^{2+}_{(aq)} in a saturated solution of CaCO_{3}? Note: T...

1) What is the pH if ammonia is mixed with water vapour? 2) What is the white smoke when I heat {eq}NH_4Cl \text{ with } Ca(OH)_2? {/eq} Ammonia Ammonia is a compound made up of hydrogen and nitrogen. It is known to have a ...
Potentiometric titration is a technique to determine the concentration of an analyte solution, volumetrically, by measuring the electric potential across the analyte (electrolyte) using a combination of indicator and reference electrode as a function of the added titrant. The point...
