Experiment 15 Title: Equilibrium studies Objective: 1. To study the effect of concentration and temperature changes on equilibrium. 2. To predict the direction of the net reaction in an equilibrium system by Le Chatelier’s principle. Results: Part 1 (a): Effect of temperature changes on equilibrium Cu(NO3)2 (aq) Cu(NO3)2 (s) The color of the solution = dark blue with precipitate When placed in water bath 60oC When placed in ice bath The level of the solid

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

Sudden Sensorineural Hearing Loss Imagine waking up tomorrow feeling dizzy‚ nauseous‚ and your ears just will not stop popping. What is wrong? After about two weeks of experiencing this all the time‚ you go to doctor after doctor trying to find out what in the world is wrong with you. Soon‚ you find your self at an otolaryngologist‚ a doctor that specializes in the inner ear. He finally diagnoses you with Sudden Sensorineural Hearing Loss (SSNHL). When I was ten years old‚ after going to

While reading Chapter 11‚ “Hearing”‚ I learned some pretty interesting things. Our ability to hear events that we can’t see serves an important signaling function for both animals and humans. For an animal living in the forest‚ the rustle of leaves or the snap of a twig may signal the approach of a predator. For humans‚ hearing provides signals such as the warning sound of a smoke alarm or an ambulance siren‚ the distinctive high indicate problems in a car engine. Hearing not only informs us about

Understanding Equilibrium in the IS/LM Model 1995 version Prof. Humberto Barreto1 Introduction: This brief work is designed to provide additional ammunition for the student in the ongoing war against IS/LM confusion and ignorance. The author has claimed in his Notes on Macroeconomic Theory (1995) that‚ There should be no mystery or uncertainty surrounding the IS/LM analysis at this point. IS/LM curves are simply a short-cut to finding the equilibrium values for income and interest rate. There

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

A Hearing Aid Might Be The Solution For Your Tinnitus Hearing loss and tinnitus often go together. Tinnitus is a ringing or whooshing sound heard inside your ear. Since the sounds originate inside of your ear‚ they are much more noticeable when external sounds are muted due to hearing loss. One possible solution to the problem is to wear a hearing aid. Here’s how it may help. Drown Out Tinnitus By Amplifying External Noise A hearing aid is a sound amplification device. When you wear one‚ the
