Give answer to the following question:
 
Write relationship between \(pH\) and \(pOH\) of aqueous Solutions at 25 °C.
 
At \(25°C\), the \(pH\) and \(pOH\) of a aqueous solution as
 
This relation helps to calculate one value if the other is known.
 
Example:

\(pOH\) of a solution is \(6.8\). What is the \(pH\) of this solution?
 
\(pH\) =
 
\(pH\) =
 
\(pH\)indicates or  concentration, whereas \(pOH\) indicates  or  concentration.
