Determination of the Solubility Product Constant of Calcium Hydroxide Introduction The equilibrium constant for the solubility equilibrium between an ionic solid and its ions is called solubility constant [1] ‚ Ksp of the solute. For example‚ the solubility product is defined by MxAy(s) ⇋xM(aq)y++ yA(aq)x- (1) Where M is the metal cation‚ A is the anion‚ x and y are the corresponding charges of the ions. The equilibrium expression is Ksp=[MY+]x[AX-]Y (2)

Photoelectric Effect: Determining Planck’s Constant Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar January 31‚ 2014 PreLab Up until the eighteenth century‚ particle theories of light dominated physics‚ primarily due to the work of Isaac Newton. Thomas Young’s 1805 famous double-slit experiment‚ which showed that light mimics a wave‚ extinguished some of these early views. However‚ in 1887‚ Heinrich Hertz – who is‚ coincidentally‚ perhaps better known for definitively

DATE PERFORMED: JANUARY 6‚ 2011 SPECTROPHOTOMETRIC DETERMINATION OF THE EQUILIBRIUM CONSTANT OF A REACTION ABSTRACT The objective of the experiment was to determine the equilibrium constant of the reaction forming ferric thiocyanate through the use of Spectrophotometry. For the calibration‚ five standard solutions were prepared‚ then their respective absorbance values that were obtained through the use of the spectrophotometer‚ were plotted versus the concentration of the analyte so that a calibration

Project Specifications Project Title: Variable Pitch Constant Rotational Speed Wind Turbine Project Aims This project can be divided into 3 three parts. The first part is to develop a variable pitch propeller. Then second and the main aim of this project is to design a control mechanism by which the propellers would rotate at a constant speed‚ at varying wind speeds by adjusting their pitch. This would be achieved by using wind sensors (anemometer) and a microcontroller. The sensors would

The argument that I am proposing is that Dr. Manhattan is in a constant state of nostalgia. As he experiences all of time at once‚ his past is becoming larger. As his past becomes larger‚ he values all those previous moments more so than his future. Dr. Manhattan values his past over his future so much so that he forces his responses in the present to be a product of his past and not his future. Perhaps a clearer way to say this is to suggest that Dr. Manhattan wants to be himself‚ and not care about

Changes Each person experiences certain things‚ even the most simplest and innocent‚ that enlighten him or her or bring about a revelation. At one point in each of our lives we will or already have had one such meaningful incident. In Annie Dillard’s short essay “Dumbstruck‚” she recounts an experience just like that. Dillard’s experience jolts her‚ bringing to life an awareness of the harshness and inevitability that things happen‚ things are not permanent in this life. We first learn of her love

Bonfa only one main idea exist. In the beginning you are able to hear all the members of the ensemble playing and then you begin to hear soloist playing. At 1.20 you hear wind instrument /s come in for their solo‚ sounds like a saxophone. There is a constant steady tempo throughout. The piano solo comes in at approx. 2.20 and plays an upbeat tune until the main theme again which repeats about 3.20 and 3.48. The vivid picture that is created in this piece relies on unity that is created by repetition
