With experimental outcomes comprising known molar concentrations and volumes of acid and base used, ph is calculated.... In place of an indicator, glass electrode is utilized so that multiple pHs may be read and graphed from which to determine the ph at the equivalence point.... For the neutralization reaction occurring between HCl (aq) and NaOH (aq): For the neutralization reaction occurring between CH3COOH (aq) and NaOH (aq): Hypothesis: The equivalence point is achieved once the titration has gone to the extent when the acid (analyte) and the base (titrant) are in equimolar amounts which takes place on yielding a neutral ph along a steep region in the titration curve Aim: To locate the ‘equivalence point' through the measure of ph based on the titrant volume vs....

2.... For each equilibrium system in question 1, above, predict the change that will occur to the position of equilibrium when the stated change occurs.... Justify each prediction by considering 'le Chatelier's Principle'
According to 'Le Chatelier's Principle', if a system at equilibrium is disturbed by a change in temperature, pressure, or the concentration of one of the components, the system will shift its equilibrium position so as to counteract the effect of the disturbance (Brown, LeMay and Bursten, 1991)....
