INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

Pre Lab: Background: The Density of a material may be determined by determining the mass and volume of a sample material and calculating the mass/volume ratio. An independent variable is the variable that is being manipulated or changed during the experiment. The dependent variable is the variable that is being measured. The independent variable for this experiment is the copper because you are only changing the amount of copper you use. The dependent variable is the density because we are measuring

Sonnet 17 Explication Who will believe my verse in time to come If it were filled with your most high deserts? Though yet‚ heaven knows‚ it is but as a tomb Which hides your life and shows not half your parts. If I could write the beauty of your eyes And in fresh numbers number all your graces‚ The age to come would say “This poet lies: Such heavenly touches ne’er touched earthly faces.” So should my papers yellowed with their age Be scorned like old men of less truth than tongue‚ And

Chemistry 266 Dominick Armstrong 10/10/2012 Acid-Base Titration Introduction Acid and bases are two important classes of compounds that react to form a salt and water. When mixing acids and bases a precise amount of the base must be added in order to reach the equivalence point. At this point‚ one reactant has been exactly consumed by the addition of the other reactant. When performing chemical reactions chemist use a process called titration to determine the equivalence point of the

Chemistry Exam Revision - Redox & Electrochemical Series - Define oxidation and reduction in term of loss and gain of oxygen; loss and gain of electrons and change in oxidation state (number). • Oxidation is the loss of electrons; an increase in oxidation state or a gain in oxygen by a molecule‚ atom‚ or ion. • Reduction is the gain of electrons; a decrease in oxidation state or a loss of oxygen by a molecule‚ atom‚ or ion. • OIL RIG (Oxidation is Loss‚ Reduction is Gain) - Rules for assigning

Ashley Huston ILab‚ Week #2 CATIONS AND ANION LAB Introduction The purpose of this lab is to demonstrate a double-replacement reaction of ionic compounds. In this experiment‚ you will combine two ionic compounds. Both compounds are soluble in water. If a response happens between these two compounds‚ then a precipitate will form because one of the two resultant compounds is not soluble in water. This is a hint that a reaction took place. Cations are positively charged ions that are attracted
