ACID ATTACKS UNDER IPC : AN ANALYSIS INTRODUCTION Acid attacks are a form of violence against women‚ where the perpetrator splashes a person or object with acid in order to deface or kill them. Although acid throwing‚ also known as vitriol age‚ has been a form of violence known to be committed throughout history‚ there has been a steep rise in the cases documented in recent years‚ particularly in certain South Asian countries. Some of this increase has been attributed to better documentation

Every element and compound has a distinctive melting and boiling point. When a substance reaches its melting and boiling point it will change phase. For example the molecules in a solid being heated gain energy and eventually are able to not only vibrate but

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

menace. Because of pollution in the air‚ acid gases from factories‚ cars and homes‚ the rain is becoming dangerous for the life of every living creature. This rain is known as ’acid rain’. WHAT IS ACID RAIN? Acid gases are produced when fossil fuels like coal and oil are burned in power stations‚ factories and in our own homes. Most of these acid gases are blown into the sky‚ and when

Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain‚ snow‚ hail‚ or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries‚ coal burning factories‚ power plants and automoble engines

Kong Acid rain on plant -Background information Unpolluted rain is normally slightly acidic‚ with a pH of 5.6. Carbon dioxide (CO2) from the atmosphere dissolves to form carbonic acid. Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition‚ which can appear in many forms. Wet deposition is rain‚ sleet‚ snow‚ or fog that has become more acidic than normal. Dry deposition is another form of acid deposition‚ and this is

One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into account

considered that rain is acid? = The pH scale measures how acidic an object is‚ when pH is lower than 7 rain is considered acid. b) Which are the compounds that in contact with water origin acid rain? = Compounds like sulfur sulphuric and nitric acids. c) Which are the principal causes of these compounds? = The extra acidity in rain comes from the reaction of primary air pollutants‚ primarily sulphur oxides and nitrogen oxides‚ with water in the air to form strong acids. The main sources of

rainfall is slightly acidic because carbon dioxide in the atmosphere dissolves in the raindrops to produce hydrogen ions. Yet‚ normal rainfall is not considered acid rain. Acid rain is a form of air pollution in which airborne acids produced by electric utility plants and other sources fall to Earth in distant regions. The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels
