  • Analysis Of Ka And Pkb

    DETERMINATION OF pKa AND pKb USING ACID-BASE TITRATIONS Introduction Acid-base titrations can be used to determine pKa of a weak acid and pKb of a base. A weak acid and a weak base incompletely dissociate in water. For this reason, the concentration of hydrogen ions (H+) and hydroxide ions (OH-) depend on equilibrium coefficients of acid (Ka) and base (Kb). Equation 1 shows the chemical dissociation equation of a weak acid. Furthermore, Equation 2 describes the equilibrium constant of a weak acid. On the other hand, Equation 3 and Equation 4 illustrate the chemical equation for the dissociation and equilibrium constant of a weak base. HA ↔ H+ + A-…………………………………………………. Equation 1 Ka=[H+][A-]/[HA]……………………………………………… Equation 2 BH+ + OH-↔ B + H2O………………………………………… Equation 3 Kb= [B+][OH-]/[BOH]…………………………………………. Equation 4 The equilibrium constants (Ka and Kb) are intrinsic properties of a particular weak/base pair. Ka defines the manner in which conjugate base holds on to the H+ (proton) while Kb describes the ‘stickiness’ of a weak acid for hydroxide ions(OH-). Taking the logarithm of…

  • No Attachment To Dust Analysis

    Humanity has a tendency to use logic and reason as much as possible to try and explain the world around us. Even in the case of religion, often there are set patterns or explanations, that always follow certain rules. Whether or not these rules comply with other rules from other ideologies isn’t pertinent; the fact remains that they follow their own logic, and that makes people happy. However, there has always been a gap in what logic and reason can explain about humanity, and what we don’t…
