Acid Attack: Should the punishment be more stringent? Ways to maim or murder our women- It never gets old. Sometimes they are killed in the womb itself‚ and if they are lucky enough to survive they are doused in kerosene and set alight‚ dragged and‚ raped‚ or Acid is thrown on their faces –perhaps the worst form of torture. Acid attack results in a living death‚ a lifetime in hell on earth. The victim becomes pariah‚ outcast from the society‚ employment and sometimes from their families too.

Acids and Bases are two groups of chemical compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are

Investigate the Effect of Acid Rain on Building Materials Question: What is the effect of 6M sulfuric acid (H2SO4) on the corrosion rate of the 3 grams of steel as the amount (number of sprays) of sulfuric acid increases? Variables: Independent variable: the number of sprays of 6M sulfuric acid (0‚ 5‚ 10‚ 15‚ 20‚ 25 times) to observe its effect on the corrosion rate. Each spray will contain about 10mL. Dependent variable: The corrosion rate. It will be calculated by measuring the mass of steel

development is Folic acid‚ which is also known as folacin‚ or folate. This nutrient is essential for the prevention of anemia‚ since it is used to make the extra blood a woman’s body needs during pregnancy. Folic acid deficiency anemia is characterized by red blood cells that are larger than normal when referring to this type of anemia. The red blood cells are also deformed‚ and both their rate of production and their lifespan are diminished (Charlish and Holt 65). Folic acid anemia occurs most often

1. Omega 3 fatty acids and Alzheimer’s disease Omega 3 fatty acids and Alzheimer’s disease how do they relate to one another? I have found in my research that omega 3 has been proven to show a delay in the process of Alzheimer’s disease and also has many other health benefits. This is my findings in doing my research. Although no one knows what causes Alzheimer ’s disease‚ many research studies indicate that those who regularly eat fatty fish or who supplement with fish oil have a lower

Percent Acetic Acid in Vinegar Introduction: Acetic acid is reactive when combined with calcium carbonate. In this lab‚ we will use vinegar for its acetic acid and egg shells for their calcium carbonate. Marketable vinegar differs in its acetic acid concentration from 4-6%. Calcium carbonate reacts with the acetic acid in vinegar to produce carbon dioxide‚ water‚ and calcium acetate as represented by the equation: CaCO3 + 2HC2H3O2 CO2 + H2O + Ca(C2H3O2)2. The calcium carbonate reacts with

almost everyone associates with acids and bases is the litmus paper‚ which has the ability to change the color in response to an acid or a base. Phenolphthalein is another common indicator use by beginners in chemistry because its color change is very obvious‚ making it easy to use. There are many other indicators that change color at different pH levels‚ and so are useful for different purposes. Many pigments found in nature can be quite effectively used as acid-base indicators. The purple eggplant
