Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

Marz Jhon V. Patricio QUANTITATIVE DETERMINATION OF THE ACIDITY OF SOFT DRINKS I. Introduction A. Principle Titration is a laboratory method that is the slow addition of one solution to another until the reaction reaches neutralization‚ which is often indicated by color change. Acid-base titration is the most frequently used procedure to determine the concentration of an acid or basic solution. This titration is also called as neutralization reaction. By adding an indicator to the solution‚ we will

------------------------------------------------- HOT ICE ------------------------------------------------- How to make own Sodium Acetate ------------------------------------------------- 1. Add 6 tablespoons of baking soda to a pot. Do not use baking powder. 2. Add 2 liters of white vinegar to the baking soda until it stops fizzing. Do this bit by bit to avoid spills and stir often. When the fizzing stops‚ the reaction is complete‚ leaving you a diluted solution of sodium acetate

Ice. What could be danger to a mother‚ a symbol to a reader‚ or a slab of frozen water to most of you is my home. It’s where I have found my true self and have grown up. Rink to rink‚ pond to pond. Anywhere I could find an opportunity to progress and do what I love. Hundreds of miles on road under my feet‚ but yet thousands on the ice. It’s never there to put me down or lift me up but to remind me where I started and where I am today. When I am on the ice I feel perfectly content and feel at home

Complexometric Determination of Water Hardness Mike Monaghan CHM 152LL 01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse

Finally‚ November first arrived. Since my birthday‚ when I received my ice-skates in the mail‚ I had counted down the days until this moment. Listening to instrumental music‚ I had envisioned myself spinning and gliding across the ice‚ as gracefully as a swan on a lake. In my head‚ I could skate both elegantly and effortlessly. Heart racing‚ I fastened my skates and stepped onto the rink. Within the first five minutes‚ I slipped and fell. Falling hurts. However‚ stumbles‚ falls and head long plummets
