Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH-] is 1 x 10-11 mol/L. Is this solution acidic, basic, or neutral? Show your work

Respuesta :

You can use the fallowing equations:
pH=-log[H⁺]
pH=14-pOH
pOH=-log[OH⁻]
[H⁺]=K(w)/[OH⁻]    (K(w)=1.01×10⁻¹⁴)

You can use any of those equation in what ever order to find the [H⁺] and then pH.  If pH>7, the solution is basic.  If the pH<7, the solution is acidic.

I will show you how I would find it but there is more than one way to do it.
[H⁺]=(1×10⁻¹⁴)/(10⁻¹¹)
[H⁺]=0.001M
pH=-log(0.0010)
pH=3.00
Therefore the solution is acidic.

I hope this helps.  Let me know in the comments if anything is unclear.

Answer:

If we have [tex][H+][OH-] = Kw = 1.0 x 10^-^1^4[/tex]

Then [tex][H+]= Kw/ [OH-]= 1.0x 10^-^1^4/ 1 x 10^-^1^1 =1 x 10^-^3 mol/L[/tex]

[tex]pH = - log [H+] = - log 1 x 10^-^3 = 3[/tex] [tex]< 7[/tex]

This is a Acidic Solution

hope this helps
