Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Tap Water Vs Bottle Water Tap Water: Tap water is the most efficient water available. Unfortunately‚ it is also vulnerable to occasional contamination. This is usually locally due to damaged pipes. This type of problem can be fixed in a timely manner. For the most part‚ the water is not much different from bottled water. It can be consumed directly from the pipes without harm. Even when the water is contaminated it is usually not fatal. Water pipes efficiently carry water across the nation as

property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water is its high

At its threshold‚ he passed the Harvester‚ Who sensed the determination of the huntsman. He besought him to reconsider continuing forward; “You will not make it far like that!” he warned. The huntsman scoffed at the first beast’s warning Presuming his words were a means of intimidation. He continued into the woods‚ where the next of the five waited‚ Leaving the gentle Harvester in a daze. Well‚ days passed‚ then weeks‚ and then months; And there was no evidence of the huntsman’s return. Many wondered

Water Crisis and Water Management in Pakistan 1- Introduction Water plays a vital role in a country’s economy. Water has been critical to the making of human history. The earliest agricultural communities emerged where crops could be cultivated with dependable rainfall and perennial rivers. Simple irrigation canals permitted greater crop production and longer growing seasons in dry areas. Some of the problems faced by the world population are as below. • More than a billion people lack access

weighing bottle was used to obtain the unknown. After obtaining the unknown‚ it was placed in a desiccator until titrating began. A 250 mL beaker was used to obtain the EDTA solution. A buret was acquired and rinsed with deionized water. After rinsing with deionized water‚ the buret was then rinsed with 5-10 mL of the standardized EDTA solution. The standardized EDTA solution was then used to fill the buret. 0.14 to 0.16 g of the unknown sample was weighed out by using the weigh-by-difference technique

DETERMINATION OF BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the
