Respuesta :
[tex]F^{-}[/tex] is most abundant and 6310 times more than HF.
What is a strong and weak acid?
An acid becomes more potent as it dissolves in water because all of its molecules break down.
When an acid is dissolved in water, only a small number of its molecules disintegrate, making the acid weak. Strong acids have a lower pH than weak acids.
The powerful acids include perchloric acid, chloric acid, nitric acid, sulfuric acid, hydrobromic acid, and hydroiodic acid.
Given:
Pka=3..2
pH=7
Let the volume be 1 liter
[HF]=01 M
[tex]pH=pka+log \frac{F^{-}}{HF} \\\\7=3.2+log\frac{F^{-}}{HF} \\3.8=log\frac{F^{-}}{HF}\\ \frac{F^{-}}{0.1}=10^{3.8} \\F^{-}=630.95 M[/tex]
Now,
[tex]\frac{F^{-}}{HF}=\frac{630.95}{0.1}\\ =6309.57[/tex]
F-:HF= 6309.57:1
Therefore, the most abundant is [tex]F^{-}[/tex]and has 6310 times more than HF is [tex]F^{-}[/tex].
