This equation relates the pH, the ionization constant of a weak acid, and the concentrations of the weak conjugate acid-base pair in a buffered solution. Scientists often use this expression, called the Henderson-Hasselbalch equation, to calculate the pH of buffer solutions. It is important to ...

I tried the Henderson-Hasselbach equation. It is not giving me an accurate enough pH. This is a very bad example for testing changes of pH during dilutions. For pH very close to 7 all diluted solutions will show practically the same pH. And, of course, an unabbreviated HH equation ...
A program for calculating the total concentrations of ligands and metals at any temperature, ionic strength and pH for solutions with a controlled metal concentration was written in Quick-Basic. For the calculation, the absolute stability constants of ligands and the proton activity coefficient were ...
Volume percent or volume/volume percent most often is used when preparing solutions of liquids. Volume percent is defined as: v/v % = [(volume of solute)/(volume of solution)] x 100% Note that volume percent is relative to the volume of the solution, not the volume ofsolvent. For exam...
When studying solutions, the exact concentration is sometimes needed. After molarity is established, dilution and actual concentration can be discussed and compared. The following is the equation used to find the power of the hydrogen concentration ion: pH= -logH3O^+ How do you calculate pH ...
摘要: The concentration dependences of the excess Gibbs energy of ternary solutions with various deviations from ideality are calculated on the basis of the non-random two-liquid (NRTL) model.关键词: ternary solutions excess Gibbs energy isoline diagrams NRTL equation deviations from ideal behavior ...
The pH scale can be traced to a series of standard solutions whose pH is defined by international agreement. By calculating the potential difference between a hydrogen electrode and a standard electrode such as the silver chloride electrode, primary pH standard values are calculated using a concentra...
Korry has a Ph.D. in organic chemistry and teaches college chemistry courses. In this lesson, we will talk about what defines a solution, an electrolyte solution, and then how to calculate the concentration of those solutions using some common units of concentration. ...
