How is the strength of a weak acid related to the strength of its conjugate base?
Strong acids and bases dissociate completely in water. Strong acids produce a pH of less than 3 and form weak conjugate bases. Strong bases produce a pH greater than 10 and form a weak conjugate acid.
What is a conjugated base?
A conjugate acid is formed when a base gains a positive hydrogen Ion (H+), and thus, having the ability to lose this ion becomes a weak acid. The opposite is true when forming a conjugate base, an acid loses a H+ ion and therefore is a base, as it is able to steal ions.
An acid has Ka 3.1 10 10 What is the Kb for the conjugate base of this acid at 25 C Kw 1.0 10 14 at 25 C?
3.2 x 10-5
An acid has Ka 2.5 10 4 What is the Kb for the conjugate base of this acid at 25 C Kw 1.0 10 14 at 25 C?
4.0 x 10-11
What is the conjugate acid?
Strongest (conjugated) Acid:hexa-Fluoro-Antimonic Acid (HSbF6 or HF.SbF5), pKa = -25It is conjugated to the base: SbF6-Classified as a "Superacid". This acid will donate proton to C2H4 to form a ethane-carbocation. Compare: pKa(HClO4) = -10, HClO4 does not react with ethene.
How is water a buffer?
Theoretically any system in which both the acid/base and its conjugate are present can be used as a buffer. Since pure water has hydroxyl and hydronium ions present at 10-7 M it can be technically called a buffering system. However, since the concentrations are so small and water offers practically no buffering capacity and in a common sense water is not used as a buffer for any reactions, only as a solvent.
What is the strongest Conjugate acid?
Strongest (conjugated) Acid:hexa-Fluoro-Antimonic Acid (HSbF6 or HF.SbF5), pKa = -25It is conjugated to the base: SbF6-Classified as a "Superacid". This acid will donate proton to C2H4 to form a ethane-carbocation. Compare: pKa(HClO4) = -10, HClO4 does not react with ethene.
A solution for which OH- equals 3.0 x 10 to the negative 10 is classified as an acid basic or neutral and how to calculate?
Base. -log(3.0 X 10^-10) = pH of 9.5
What is the conjugate?

A pH of 10 is an acid or base?
A pH of 10 is definitely a Striong Base.
