Respuesta :
At room temperature, number of moles of distilled water is 1 x10^-7. Hope it cleared your doubt.
Answer : The correct option is, [tex]1\times 10^{-7}[/tex]
Explanation :
As we know that the ionic product of water is the product of the concentration of hydrogen ion and the concentration of the hydroxide ion.
In the pure water, the concentration of hydrogen ion and the concentration of the hydroxide ion are equal.
Mathematically,
[tex][H^+][OH^-]=1\times 10^{-14}mole/L[/tex]
When [tex][H^+]=[OH^-][/tex]
[tex][H^+]^2=1\times 10^{-14}mole/L[/tex]
[tex][H^+]=1\times 10^{-7}mole/L[/tex]
Therefore, the number of moles of [tex][H^+][/tex] ions in a liter of distilled pure water is, [tex]1\times 10^{-7}[/tex]
