Nitric Acid Nitric acid is an acid many people have come across in life. One may have felt nitric acid when touching fertilizers‚ or using dyes. Nitric acid appears in substances we never thing it would be used in. In fact‚ small contents of nitric is acid is found in raindrops that fall from the sky. Nitric acid‚ or known as NHO3aq is an acid formed from reaction of ammonia and oxygen. Nitric acid is a colourless acid when it’s pure‚ or can be found yellow or red. This acid can be very corrosive

Acid Base And Salt Acid Acids:- The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour‚ such as curd‚ tamarind‚ lemon‚ etc. Types of Acids:- Acids are divided into two types on the basis of their occurrence – Natural acids and Mineral acids. Natural Acid:- Acids which are obtained from natural sources are called natural

PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the

form of a hydrogen ion. This is what we call the Bronsted-Lowry definition of an acid‚ which is the main focus of this lesson. !!!What is a Bronsted-Lowry Acid? What makes a solution an acid? There are different definitions proposed by different scientists about what makes an acidic solution. Particularly‚ there were two scientists who independently proposed essentially the same theory about the definition of acids and bases. In 1923‚ Johannes Nicolaus Bronsted and Thomas Martin Lowry‚ from Denmark

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

In this report‚ I will explain what Sulfuric Acid is‚ the health risks and hazards associated with it‚ the safety precautions that should be taken and how the spill should be handled. Sulfuric Acid‚ H2SO4‚ also commonly known as battery acid or vitriol‚ is one of the top products in the chemical industry‚ with 40 million tons produced annually in the U.S. It is a colourless‚ odourless and oily mineral acid that is soluble

Acid rain‚ or more accurately acid precipitation‚ is the term used for describing rainfall with a pH level lower than 5.6. This type of pollution is a matter of great debate currently due to the potential of its causing environmental damages all across the world. For the last decade or so acid rain has caused destruction to hundreds of lakes and streams in many parts of the world‚ including the US‚ Canada‚ and Europe. Acid rain forms due to the oxides of sulfite and nitrogen combining with the moisture
