Naoh Concentration Ph Table

How to Calculate pH in Chemistry | Albert.io

 · For example, when NaOH (sodium hydroxide, a common base), is placed in water, it dissociates into two kinds of ions, Na + and OH –. The high OH – concentration, which corresponds to a low H + concentration, is a property of basic solution. Table 2. Relationship Between pH and pOH

CHEM 1332 (A.M. Guloy) CHEMICAL EQUILIBRIA--ACID/BASE

A typical strong base problem might be: What is the pH of a 0.010 M NaOH solution? Since NaOH is a strong base, the hydroxide ion concentration will be equal to the NaOH concentration: [OH-] = 0.010 M The pH can be found by first finding the pOH by taking the negative log of the hydroxide ion concentration, and then converting the pH to pOH.
