DISCOVERIES IN CHEMISTRY AND THEIR IMPACTS ON PUBLIC LIFE INTRODUCTION Every single day‚ without even realising it‚ we use so many things that are brought to us by the discoveries and advances in chemistry. Many of these things we take for granted‚ and don ’t even bother to question how it got there‚ why it is there‚ and how it works. Chemistry makes up everything in our lives‚ from the air that we breathe‚ to the plastic on the keyboard I ’m typing on now‚ and a in depth study of some of the

Role of Chemistry in Every day Life Chemistry has played a key role in determining the nature of the modern world. In reality chemistry is much interesting for both study and practice. While defining chemistry let us consider a traditional definition which states ’Chemistry is the science of matter which undergoes changes during chemical reaction’. But in reality chemistry goes beyond its traditional definitions. From the evolution of mankind itself‚ chemistry had a close connection with the daily

John Abarshi Mr Meinsma Chemistry December 14‚ 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity‚ then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any type of solution‚ even ionic solutions‚ provide
