This is the question
" If a soution has a pOH = 10, then the pH= "
PH + POh=14 is the equation
yes that is the equation dear...for more information, look the example i have given out here dear to prove that
Why pH + pOH = 14
Water ungergoes auto or selfionization as shown in the following equation.
2 H_{2}O > H_{3}O^{+} + OH^{}
An equilibrium is established between the ions produced and the unionized water. An equilibrium expression can be written for this system.
K_{w} = [H_{3}O^{+}][OH^{}]
K_{w} is used to represent the equilibrium constant for the ionization of water. It is a special notation of the general representation K_{c}.
The value of K_{w} when measured at 25°C has been determined to be 1 x 10^{14}.
Mathematically, if one takes the log of both sides of the equation, remembering that when numbers are multiplied their logs are added, we arrive at the following equation.
log (1 x 10^{14}) = log [H_{3}O^{+}] + log [OH^{}]
The log (1 x 10^{14}) =  14.
Thus,  14 = log[H_{3}O^{+}] + log [OH^{}]
Multiplying both sides of the equation by 1, we get
14 =  log [H_{3}O^{+}]  log [OH^{}]
The  log [H_{3}O^{+}] is defined as the pH, and the  log [OH^{}] is defined as the pOH. Substituting into the equation yields the relationship between pH and pOH of a solution.
14 = pH + pOH
