Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine

TOPIC - 2 DEMAND‚ SUPPLY AND MARKET EQUILIBRIUM The term ‘price’ has a great relevance in economics. In ordinary usage‚ price is the quantity of payment or compensation given by one party to another in return for goods and services. It is generally expressed in terms of units of some form of currency. But how does a product sell for a certain price‚ what constitutes the price of a product and how is the price determined is the bigger question. In economics‚ for a competitive market

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

Demand‚ Supply and Market Equilibrium Every market has a demand side and a supply side and where these two forces are in balance it is said that the markets are at equilibrium. The Demand Schedule: The Demand side can be represented by law of downward sloping demand curve. When the price of commodity is raised (ad other things held constant)‚ buyers tend to buy less of the commodity. Similarly when the price is lowered‚ other things being constant‚ quantity demanded increases. The above
