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

Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen

MSG or monosodium glutamate is a sodium salt of glutamic acid which can be naturally found in many common foods that are rich in protein content such as dairy products‚ meat‚ vegetable and mother’s milk. In fact‚ our own bodies do produce glutamic acid via Krebs cycle during metabolizing food. Glutamate is the most abundant naturally occurring non-essential amino acid (Ninomiya‚ 1998) and it is a very common part of our diet. In the food industry‚ MSG is widely used as a flavor enhancer. It is responsible

Osmosis in Potato Tissue Experiment Background Information Osmosis can be defined as the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration. The semi-permeable membrane allows small particles through it but does not allow large particles such as sodium chloride. Osmosis will continue until a state of equilibrium is reached i.e. there is no area with a higher or lower concentration than another area

Sodium is an electrolyte that controls the fluids in the body’s tissues and cells. It is also responsible for regulating blood pressure and volume‚ helping transmit impulses‚ and regulating the balance of blood and body fluids. I believe it is important to monitor your sodium intake in order to stay in good health. Kidneys are the most common concern when too much sodium is being taken in because it can lead to damage to the heart. When there is an excessive amount‚ the kidneys are unable to

Drinking too much water can lead to hyponatremia‚ water intoxication‚ water poisoning and death Liquid H2O is the sine qua non of life. Making up about 66 percent of the human body‚ water runs through the blood‚ inhabits the cells‚ and lurks in the spaces between. At every moment water escapes the body through sweat‚ urination‚ defecation or exhaled breath‚ among other routes. Replacing these lost stores is essential but rehydration can be overdone. There is such a thing as a fatal water overdose.

Chemistry Lab Report Stoichiometry Design Experiment Percentage Yield of Calcium Carbonate and HCl I. Background Information When marble chips and hydrochloric acid are added together‚ they form sodium chloride‚ water‚ and carbon dioxide. This reaction can be displayed by the balanced equation below; CaCO3 (s) + HCl (l) NaCl(s) + H2O(l) + CO2 (g) As the carbon dioxide is formed‚ it will leave the open beaker as a gas. This will result in a loss of mass. The mass change can then be

how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement of molecules along the concentration gradient. In this case we will be looking at the diffusion of acid in
