determined by the amount of hydronium ion formed in water. Most often‚ it is expressed by pH‚ which equals the –log[H3O+]. The equilibrium constant for an acid is represented by Ka = [H3O+] [A-] / [HA]‚ where HA is the acid and A- is the dissociated acid. When comparing Ka’s‚ most commonly pKa is used‚ which is equal to –log Ka. In this experiment‚ the pKa of an unknown acid is determined by titrating it with NaOH and graphing its pH levels versus volume of NaOH titrated. The inflection point found

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor.

Compare and Contrast Two Business Leaders——Li Ka-shing and Bill Gates Due to tremendous disparities in historical background and civilization between Chinese and Western countries‚ there exist remarkable differences between Chinese and Western business leaders. However‚ both of them still have similarities. This essay will take Li Ka-shing and Bill Gates as representatives to illustrate the differences and similarities between Chinese and Western business leaders. One obvious difference is

Përveç kësaj‚ Shqiperia ka një ekonomi relativisht e vogël dhe e hapur ndaj zhvillimeve në vendet e tjera në rajonin e Ballkanit‚ me pjesën tjetër të Evropës Qendrore dhe Lindore ose në Bashkimin Evropian (BE) mund të ketë një ndikim të rëndësishëm negativ midis te tjerave

lab the acid Potassium hydrogen phthalate and two unknown acids were titrated. We determined the molar mass of the Potassium hydrogen phthalate‚ for the unknown acids we calculated the molar mass and the Ka values. We used NaOH as the known base for titrating in all three of the titrations. Our ka value based on our titration curve of KHP was 6.9 (the equivalence point where the pH equals the pKa) and our unknown acids were determined to be Hexanoic Acid (with an actual molar mass of 116.6g) with
