What is the conjugate base of carbonic acid, H2CO3? What is the conjugate acid of the given base? Write the formula of the conjugate base for acid H_3O^+ and what is the name of the base? From what acid and what base are the following salts made: KBr, NH_4NO_3, and BaCl_2...
The basicity of a solution is determined by electron pair availability. The more electrons that are available, the more easily they'll form new bonds with the protons in the solution, and so the stronger will be the base. Basicity can thus be defined as how prone a solution is to forming...
What is the pH of a buffer prepared by adding 30.0 mL of 0.15 M {eq}\rm HC_2H_3O_2 {/eq} (acetic acid) to 70.0 mL of 0.20 M {eq}\rm NaC_2H_3O_2 {/eq} (sodium acetate)? Acidic Buffer Solution: An acidic buff...

What is the conjugate acid of A? What is the conjugate acid of HS-? H2S- S- H2S S2- What is the conjugate acid of H2S? What is the conjugate acid of H_2C_6H_7O_5^-? What is the conjugate acid of NH2? What is the conjugate acid for NH3?
What is Kb for ClO− if Ka for HClO is 3.5 x 10−8? Base Dissociation Constant of a Conjugate Base: The acidity of a weak acid is described by the acid dissociation constant Ka. Weak acids also produce their conjugate base upon hydrolysis in water. This base will have a base dissoc...
What are the formula and name of H+ and I- in an aqueous solution? Write the formula of the conjugate base for acid H_3PO_4 and what is the name of the base? Give the formula for each acid. a.) perchloric acid b.) hydroiodic acid If an acid is made...
What is the role of buffers? Composition of Buffers: Buffers with a maximum buffering capacity are solutions containing equimolar amounts of either: A weak acid with a salt containing its conjugate base. A weak base with a salt containing its conjugate acid. ...
What is the relationship between pKa and pKb values? Ka, Kb, and Kw: For any given conjugate acid-base pair, where Ka is the acid dissociation constant, and Kb is the base dissociation constant, Ka and Kb's product is equal to Kw, the autoionization equilibrium constant for water. Answe...
