Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries

different melting point expected for the pure compound and a broadening of the melting point range. Such an observation would indicates that a compound is impure. In experiment 3.2‚ 0.120g sample of benzophenone was obtained from stock and crushed into a fine powder. Two samples of the benzophenone were loaded into a capillary tube. The capillary tubes were then individually placed in a Mel-Temp apparatus where they were gradually heated at a steady rate of 1º/minute. The melting rate was manually

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side

Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

Borneol; An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment‚ the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly‚ to produce a secondary alcohol from camphor via a reduction reaction. Therefore‚ the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation

LU 3 Oxidation and Reduction Reactions 3.1 Ideas of Oxidation and Reduction Oxidation of an atom can be occurred in the following conditions: 1. Losing an electron from the orbitals. e.g.: A A+ + e- 2. Adding an electronegative element (e.g.: F‚ Cl‚ Br‚ O) to a molecule. e.g.: A + F AF 3. Losing hydrogen
