revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the solid appeared‚ I poured in sulfuric acid to it and I got copper sulfate‚ a bluish solution. The final step I took was

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

Life Cycle of Bacteriophage. Bacteriophage: Bacteria eating virus is called bacteriophage. Life Cycles: There are 2 types of lifecycles that occur in the bacteriophage: 1) Lytic Cycle 2) Lysogenic Cycle 1) Lytic Cycle: In lytic cycle‚ virus that is the bacteriophage causes lysis of the host cell. It is virulent phage. 2) Lysogenic Cycle: In lysogenic cycle‚ the bacteriophage does not cause lysis

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

The Foods to Avoid that Causes Acid Reflux Problems in the digestive system should not be neglected. There are different possible digestive system disorders or diseases that are most often neglected by many people. The most common digestive problem is the acid reflux or gastro-esophageal reflux disease‚ mostly known as heartburn. Acid reflux affects different ages from infants to young children and adults as well. This disorder should be given special attention because it can lead to a more serious
