Diffusion of Ammonium hydroxide with red litmus paper Definition of diffusion 1. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out. 2 Diagram. 3. During the diffusion tube experiment I noted that firstly ammonium hydroxide was placed on to a piece of cotton wool. The cotton wool (with the ammonium hydroxide) was then placed in to a diffusion tube containing around 10 pieces of curled red

For Lab 1‚ my partner and I will be demonstrating the law in which connects the period of the pendulum‚ expressed as T‚ to the length of the string‚ expressed a L. The system the lab will be based on will include a pendulum with a weight of W suspended at a fixed point by the string with a variable length of L and an angle theta to be measured using a protractor. The variable T will be measured as the period of time needed for the weight of the pendulum to swing back and forth once. For part 1 of

Willy Rupprecht Date(s) performed: October 2 - 3‚ 2012 Gravimetric Analysis of an Unknown Group 1 Metal Carbonate Purpose: The purpose of this lab is to determine the identity of a Group 1 metal carbonate compound by gravimetric analysis. Procedure: The unknown carbonate is weighed and then dissolved in water. A solution of CaCl2 (calcium chloride) is added to the metal carbonate solution to precipitate the carbonate ions as CaCO3 (calcium carbonate). The precipitate is then filtered‚ dried

Chapter 1 By: Ciara Rafferty “You see I think everything’s terrible anyhow‚” she went on in a convinced way. “Everybody thinks so—the most advanced people. And I know. I’vebeen everywhere and seen everything and done everything.” Her eyes flashed around her in a defiant way‚ rather like Tom’s‚ and she laughed with thrilling scorn. “Sophisticated—God I’m sophisticated!” (21). This passage perfectly depicts the unhappiness that Daisy experiences from day to day. The life that she had

Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration‚ water will move across the membrane in response to this concentration. While conducting this lab we were able to observe passive transport through diffusion and osmosis. Introduction Osmosis is a specialized case of diffusion that involves the passive transport of water. When osmosis occurs

What is the effect of different solutions with various concentrations on plant cells? Hypothesis: 1. In an animal cell in a hypertonic solution the egg will swell‚ in a hypotonic solution the egg will swell. 2. In a plant cell in a hypertonic solution it will shrink‚ and in a hypotonic solution

concerned with Irish history. Looming over the scene depicted is the spectre of the potato famine that afflicted Ireland from 1845-49. The potato crop‚ staple for the Irish‚ failed‚ and with cataclysmic results. About half the population of three million died‚ while a million people emigrated – many to America. The first section of the poem is written in alternately rhymed quatrains that describe a rural scene of potato digging that is clearly in progress much later than a similar scene around the time
