SUMMARY

Mixing a base with a pH of 8 and a base with a pH of 14 results in a final pH that will fall between 8 and 14, influenced by the concentrations of each base and their respective pK values. The final pH can be calculated using the Henderson-Hasselbalch equation, considering that pH is logarithmic in nature. A base with a pH of 8 is considered weak, and its hydrolysis behavior in the presence of a stronger base must be analyzed in terms of reaction rates.

PREREQUISITES
  • Understanding of pH scale and logarithmic relationships
  • Familiarity with the Henderson-Hasselbalch equation
  • Knowledge of base strength and hydrolysis
  • Concept of concentration effects on pH
NEXT STEPS
  • Research the Henderson-Hasselbalch equation in detail
  • Explore the concept of base strength and its measurement
  • Study the effects of concentration on pH and chemical reactions
  • Learn about hydrolysis rates of weak bases in strong base environments
USEFUL FOR

Chemistry students, chemical engineers, and anyone interested in acid-base reactions and pH calculations.

Say i were to mix a basewith a pH of say 8, with a pH 14. what would my final pH be? 11?

it depends upon the concentrations of each, and the pK of the bases - but it is safe to say that your pH will be somewhere between 8-14.

the exact pH will follow the Henderson-Hasselbach eq.
 
...and of course, the volume of each base matters.
 
It would *have* to follow a non-linear mixing formula, since the pH number is logarythmic. pH9 is 10x more alkaline than pH8; pH10 is 10x more alkaline than pH9.
 
a base with a pH of 8 is very weak, do you think that the weak base will hydrolyze more or less when there already exists a significant concentration of hydroxide (consider this problem in terms of rates). I'll explain the specifics later.

Not necessarilly. It can be strong, but diluted.

in the relative sense, as mentioned in the original post, yes it would be very weak...compared to one which would register a pH of 14.
