Comprising 17 rounds, the series runs from January until May, crowning supercross champions in both the 250cc and 450cc classes, concluding with the Salt Lake City round on May 10. [1]
The 2025 ATP Tour is the global elite men's professional tennis circuit organized by the Association of Tennis Professionals (ATP) for the 2025 tennis season. The 2025 ATP Tour calendar comprises the Grand Slam tournaments, supervised by the International Tennis Federation (ITF), the ATP Finals, the ATP Masters 1000, the United Cup (organized with the WTA), the ATP 500 series and the ATP 250 ...
The Charlot equation, named after Gaston Charlot, is used in analytical chemistry to relate the hydrogen ion concentration, and therefore the pH, with the formal analytical concentration of an acid and its conjugate base. It can be used for computing the pH of buffer solutions when the approximations of the Henderson–Hasselbalch equation ...

In chemistry and biochemistry, the Henderson–Hasselbalch equation = + ([] []) relates the pH of a chemical solution of a weak acid to the numerical value of the acid dissociation constant, K a, of acid and the ratio of the concentrations, [] [] of the acid and its conjugate base in an equilibrium.
The ATP 250 tournaments (previously known as the ATP World Tour 250 tournaments, ATP International Series, and ATP World Series) are the lowest tier of annual men's tennis tournaments on the main ATP Tour, after the four Grand Slam tournaments, ATP Finals, ATP Masters 1000 tournaments, and ATP 500 tournaments.

After rearranging the expression defining the acid dissociation constant, and putting pH = −log 10 [H +], one obtains pH = pK a – log ( [AH]/[A −] ) This is a form of the Henderson-Hasselbalch equation. It can be deduced from this expression that when the acid is 1 % dissociated, that is, when [AH]/[A −] = 100, pH = pK a − 2
