6.00x10-3 mol of HBr are dissolved in water to make 12.0 L of solution. What is the concentration of hydroxide ions,

Respuesta :

Answer:

The [tex][OH^{-}][/tex] is [tex]2\times10^{-11}[/tex]

Explanation:

Number of moles of HBr= [tex]6.00\times 10^{-3}[/tex]

Volume of water = 12.0 L

[tex][HBr]= \frac{6.00\times 10^{-3}}{12}M[/tex]

[tex][H^{+}]= \frac{6.00\times 10^{-3}}{12}M[/tex]

[tex][H^{+}][OH^{-}]= 10^{-14}[/tex]

[tex][OH^{-}]= \frac{1.0\times 10^{-14}}{[\frac{6 \times10^{-3}}{12}]}= \frac{12 \times 10^{-14}}{6 \times10^{-3}}=2\times10^{-11}[/tex]

Therefore, [tex][OH^{-}][/tex] is [tex]2\times10^{-11}[/tex].
