Nitric acid is a highly reactive oxidizing agent used in making fertilizers‚ explosives‚ and rocket fuels‚ and in a wide variety of industrial metallurgical processes. It is also a component of acid rain. Its chemical formula is HNO3 and it has been known as “aqua fortis”‚ which means strong water‚ to alchemists. It is a transparent‚ colorless to yellowish‚ fuming corrosive liquid. Nitric acid is a strong acid and therefore it completely dissociates in water. It has a gravity of 1.41 and the concentration

Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

Zinc Tris-thiourea Sulfate (ZTS) is a Semi Organic Nonlinear Optical (NLO) material which finds applications in the area of laser technology‚ optical communication‚ data storage technology‚ and optical computing etc. The author has successfully grown ZTS crystal by gel method. Gel technique has been adopted at ambient temperature to attain better result. The grown crystals were transparent and colourless. The crystal size has been obtained the range about 5mm X 3mm X 2mm. Thermal study of ZTS crystal

Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if you are asked to name the

There are eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species

Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same
