AP Chemistry Chapter 17 Additional Aspects of Aqueous Equilibria Chapter 17. Additional Aspects of Equilibrium Common Student Misconceptions • • • • • Students often believe that the pH at the equivalence point for any titration is 7.00. In terms of problem-solving skills‚ this is probably the most difficult chapter for most students. Students tend to find buffers particularly difficult to understand. Students often forget to consider volume changes that occur when two solutions

1 Measuring and calculating equilibrium constants Clearly‚ if the concentrations or pressures of all the components of a reaction are known‚ then the value of K can be found by simple substitution. Observing individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure

KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on
