EXPERIMENT 1: WATER CRYSTALIZATION OBJECTIVES: To determine the percentage of water in aluminium sulphate hydrate To calculate the water of crystallization for aluminium sulphate hydrate To prove that a hydrate solution will lose some of it mass after heated INTRODUCTION A hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce

researching for this essay explaining what soil and water conservation means to me‚ I found two quotes that really stuck out to me. One written by Franklin D. Roosevelt stated‚ “A nation that destroys its soils destroys itself. Forests are the lungs of our land‚ purifying the air and giving fresh strength to our people.”‚ and another that was written by an unknown author read‚ “Water is life’s mater and matrix‚ mother and medium. There is no life without water.” I am not sure about you‚ but I love the life

Water. The source of life and great mystery. This flowing and unpredictable‚ yet somewhat constant‚ body of mass has filled us with wonder and left us marvelling‚ for as long as we know‚ at which secrets and mysteries that might be lying beneath the surface. Inspiring poets and artists everywhere‚ our world’s most dominating ingredient has‚ with its many states and forms‚ become not only a picture of beauty in nature but also one of the ultimate symbols of the unknown‚ and thus a cause of fear for

THE EFFECTS OF COLD ON BLOOD PRESSURE AND PULSE Abstract The ability known as thermoregulation is a feature of an organism that help to keep the body temperature within certain thresholds‚ thus independently from external conditions. A dynamic state of thermal balance of human body between its internal environment and the territory is a model example of precise control of organism heat. In the case where such stability would be disturbed the immediate response would appear as well. In accordance

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential.
