Cyclohexanol was oxidized to cyclohexanone using sodium dichromate in the presence of sulfuric acid. * Note: you can download a free version of a structure editor from ACD labs‚ the PC version is called chemsketch‚ the Mac version is called marvinsketch. You should learn how to draw structures using these programs. Lab reports should look professional

The effect on the pH of Distilled water‚ Potato Solution and Commercial Buffer‚ when Hydrochloric acid (0.1 mol/L) and Sodium Hydroxide (0.1 mol/L) is added Mahima Mandava Mrs. Haist September 23rd‚ 2014 SBI4U1 Background Information: The pH is the measurement of how acidic or how basic a substance can be. The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic‚ 8-14 being basic and 7 being neutral. There are many factors

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

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
