One such scale that is very popular for chemical concentrations and equilibrium constants is based on the p-function, defined as shown where “X” is the quantity of interest and “log” is the base-10 logarithm:pX = −log XThe pH of a solution is therefore defined as shown here, ...
There also exists a pOH scale - which is less popular than the pH scale. pOH is the negative of the logarithm of the hydroxide ion concentration: pOH=−log([OH−]),pOH=−log([OH−]), or: [OH−]=10−pOH[OH−]=10−pOH pH and pOH are related to one another by this...

pH and pOH Scale: Both the pH and pOH are p-functions that are able to give the acidity or basicity of a solution. The equation that relates these two values are: 14=pH+pOH This equation was derived from the ion-product constant expression for water. At 298 K, the ion-product con...

The pH and pOH scales typically range between 0 and 14. However, it is possible to have values outside this range. the pH and pOH values can be negative values or values more than 14. Answer and Explanation:1 Calculate the hydroxide ion concentration {eq}\rm [OH^-]...
pH: A measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. The pH scale commonly in use ranges from 0 to 14.
Step 2) Calculate the pOH pH + pOH = 14 10.0 + pOH = 14 pOH = 4.0 Step 3) Calculate the [OH 1- ] pOH = - log [OH 1- ] [OH 1- ] = 10 -OH [OH 1- ] = 1 x10 -4 M 1 x10 -4 M 0.5 x10 -4 M 5 x10 -5 M Step 4) Solve for moles of Mg(OH) 2 L mol...
“really introduced the pH scale,” which seems to give Sørensen only a derivative role in the innovation.Footnote2However, neither Friedenthal nor others suggested the convenient logarithmic scale prior to Sørensen’s definition ofpH=−log[H+]. This formulation was, in a sense, just the...
