A buffer is a system of a weak acid and its conjugate base or a weak base and its conjugate acid. In the case of HCN, it is a weak acid and it's conjugate base would be CN-. You can make a buffer by adding a salt of the conjugate base such as KCN or NaCN to HCN.

WebStrong acids have a weak conjugate base. Example: HCl is a strong acid. If HCl is a strong acid, it must be a good proton donor. HCl can only be a good proton donor, however, if the Cl - ion is a poor proton acceptor. Thus, the Cl - ion must be a weak base. Strong bases have a weak conjugate acid. WebSolution. Verified by Toppr. Correct option is A) The conjugate base of a weak acid is usually a strong base because the conjugate base of an acid is the anion that results in when acid molecules lose its hydrogen to base. Hence, option A is correct. Was this …
Webweak acid in water • Be able to use Kb to calculate the concentrations of all species present in a solution of a pure weak base in water • Be able to determine and use Kb for a conjugate base, given Ka of its conjugate acid, and vice versa. • Be able to predict … WebThus acids that are stronger than the hydronium cation, H 3 O (+), and weak acids having conjugate bases stronger than hydroxide anion, OH (–), cannot be measured directly in water solution. Solvents such as acetic acid, acetonitrile and nitromethane are often used for studying very strong acids.
