\(pH = pKa + log_{10}\dfrac{[A^{-}]}{[HA]}\) This means that given an acid's pKa and the relative concentration of anion and "intact" acid, you can determine the pH. Ka values can be easily looked up online, and you can find the pKa using the same operation as for pH if...
the pH value at which half of an acid has donated its protons while the other half remains in the conjugated state. (Bases have, you guessed it, pKbvalues.) Stronger acids thus have lower pKavalues.

Question: How does the ratio of an acid to its conjugate base in a buffer determine its pH? Ratio of an Acid to its Conjugate Base: The ratio between the concentrations of an acid and its conjugate base determines the strength of the acid. The higher the value of th...

These new mols are used to find the pH. What equation is used for calculating the pH of an acid buffer? To calculate the pH of an acid buffer, the Henderson-Hasselbalch equation is used, which is pH = pKa + log(acid/base). The acid's concentration is on top of the fraction, and...
An increase in the amount of hydroxide ions (OH-) causes the water to become more alkaline. When measured, this is referred to as the pH of the water. If you are finding that concept a little too complicated, don’t worry….

How are the K_a and K_b values of an acid and base used to determine the acidic or basic nature of their aqueous salt solution? What is the quickest way to find out whether a compound is acidic or basic? What is a more accurate (quantitative) way of finding out whether a compo...
