CHEM 301 LECTURE Unit 1 0 . COORDINATION CHEMISTRY Factors t hat affect solubility: Common ion: decrease in solubility Complex ion: increase in solubility How does complex ion formation increase solubility? Consider the complex ion formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water

Introduction Chemistry: Chemistry is the science of matter‚ especially its chemical reactions‚ but also its composition‚ structure and properties. [pic] Daily Life: All the things that happen or that you do regularly. Chemistry in Daily Life: Chemistry is a big part of our everyday life. We find chemistry in daily life in the foods we eat‚ the air we breathe‚ our soap‚ our emotions and literally every object we can see or touch. Here’s a look at some everyday chemistry. [pic] Actually‚ we found

A World Without Chemistry A world without chemmistry would be simply disastrous.We would have no phones‚ no lightbulbs‚ no social networking! Almost everything we use in our daily lifes depends on chemistry to exist‚ from the food we eat to the clothes on our backs. If we had never studied chemistry we wouldn’t have liquid oxygen. This was developed in the 1800s and is now probably best-known for its role as rocket fuel. Without rockets the space race wouldn’t have happened‚ or all the everyday

Stage 2 Chemistry Investigation Folio: Practical – Galvanic Cell Name: YY Names of Partner: ZZ Part A Investigation Design Proposal: Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current‚ the greater the flow of current will be produced from the galvanic cell. Independent Variable: Concentration

Botany and many others. Chemistry is one such branch of Science where we learn about various elements in nature and also about their physical and chemical properties. We even have Chemistry as a subject in schools. Some students find Chemistry boring but it is a really interesting subject for those who love to explore the world of Chemistry. We come across various things and happenings in our lives. The reasons for almost all of the happenings have their roots in Chemistry. We learn about the structure

Ahmed Fun Filled Hands On Science 17 January 2013 Demonstrations in Chemistry Class Chemistry is a class that a lot of college student are afraid of‚ and when I think of chemistry‚ complex equations that don’t benefit come to my mind. The reason is that all I got out of chemistry is those unbeneficial equations‚ for me at least. Also‚ I learned that H2O is water. With all those negative statements‚ I still believe that chemistry is a very important subject to understand the magic of this life and

Alchemy vs. chemistry Some people think that chemistry is just about mixing things up and experimenting in test tubes and explosions. Actually chemistry studies everything around us and how they change‚ for example it tells what your body is made out of. We study chemistry in biology‚ geology‚ engineering‚ and even physics. Chemistry is the science of matter‚ and how it changes and its chemical reactions‚ it’s also called as the central science ( the main one) because it connects physics with other

Chemistry in everyday life : Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology‚ physics and mathematics are all dependent on chemistry and are known as specific studies under the elaborate subject of chemistry. Since there is chemistry seen in biological forms as well as physical states of nature‚ there
