pOH to pH pOH is a measure of the concentration of hydroxide ions (OH–), and the sum of pH and pOH is always equal to 14. For example, sodium hydroxide (NaOH) is a strong base that completely dissolves in water
pH equation for calculating strong base :pOH = -log(OH−). pH=14-pOH Note: Strong acids and strong bases completely dissociate in a solution In the next section, two example problems will help you learn how to calculate the pH of a strong acid-strong base solution. ...

pH can be calculated from ion concentration using either of the three variables. a. Concentration of hydrogen ions [H+]; b. pOH value; and c. Concentration of hydroxide ions [OH-]. You may input any one of them, and the remaining will be calculated, along with the result: the pH val...

Methyl red has the following structure: What is the color change and the pH at the color change when a weak base is titrated with a strong acid using methyl red as an indicator? For which of these two types of titrations is methyl red a possible indicator ...
Strong acids have low pH values. Water is neutral, with a pH of 7; strong bases, or proton acceptors (such as sodium hydroxide, NaOH) have high pH values, some close to 14.0.Moles and Molarity For acid-base chemistry purposes, it is more appropriate to measure solute concentration in mol...

But, to the confusion of novices in chemistry, he did not, possibly because pH would then be a negative number (as it is only for concentrated solutions of strong acids). Sørensen only referred sparingly to the dimensionless pH quantity in his 1909 treatise where the synonymous noun ‘...
