Summary
Titration In chemistry, a solution is a mixture of two or more homogenous substances, and commonly, the components of the solutions have to be determined. The basic definitions in a solution include the solvent, which is the mixing agent in the solution, the solute, which is the substance dissolved in the solute, and the concentration, which is the amount if solvent, dissolved in the solute (Tro 25)…

For example, titration is used to determine the molarities of substances in a chemical solution or substance. The molarity of a substance refers to the quantitative expression of the concentration of a substance, which can be determined by titration (Tro 20). In the determination of the molarity, a known substance whose concentration is not known is called an analyte, and the other known substance whose concentration and molarity is known is called the titrant. The titration process is based on a chemical formula used to determine the molarity of a substance, where the elements in formula are the molar concentration, the volume of the analyte used, and the molar mass of the substance. The formula is, where c refers to the molar concentration of the substance, m is the number of moles of the substance, and v is the volume of the substance used (Tro 29). The titration procedure is divided into the following steps (Tro 130). 1. The solution of the analyte is placed in a titration flask, where the analyte refers to the known substance of unknown concentration. 2. A burette is filled with a titrant of known concentration, where the titrant refers to the solution whose concentration and volume is known. 3. ...
This means that the indicator is a substance used to determine the PH of a substance, where the PH refers to the acidity of basicity of a substance. 4. The titrant is then added from the burette into the titration flask drop-by-drop, while carefully monitoring any color change in the titration flask. 5. The titration continues until the point where the color of the solution in the titration flask suddenly changes color. As previously stated, the color of the indicator in the solution is always known; therefore, when the solution changes color to indicate a neutral solution, the titration process is stopped. At this point, it is known that the titrant and the known volume of the analyte have completely reacted to give a neutral solution. This point is called the end-point of the solution, and it corresponds to a perfect stoichiometric solution between the two solutions; the titrant and the analyte. 6. At this point, the burerte is rad to determine the amount of titrant that was used to reach the endpoint of the solution, after which the molarity of the unknown substance, the analyte, can be calculated using the formula stated above. Evidently, titration can be of many forms, since it is not only acids and bases that can be titrated. Titration reactions are usually divided into four common forms, with the first and most common being acid-base titrations. In this case, the molarity of an acid is determined using a standard solution of a base, or the molarity of the base is determined using a standard solution of an acid. These two forms of titration are called acidimetry and alkalimetry respectively (Tro 136). The second type of titration is called an oxidation-reduction reaction, or redox reactions, where the Read More

...CHEMISTRY QUESTIONS Presented Intramolecular forces operate within the molecules or fundamental units of a substance. This would include the attraction between positive and negative ions in a crystal of an ionic compound, the covalent bonds in a molecular substance as well as the covalent bonds linking atoms in a network structure, such as that of carbon (diamond).Metallic bonds are also classified as intramolecular forces (Frederick, 1979, P.63)Intermolecular forces operate between, rather than within, the molecules of a covalent substance. This would include the attractions exerted by one molecule of a molecular substance on another, such as the force of attraction between water molecules in ice ,the attractions between atoms... relative...

...x100 = 65.62%. 137x27 Question – 3 a. In 1870, Markonikov laid down a basic principle of chemistry that holds till today. The Markonikov Rule states that when a hydrogen halide (Hydrochloric acid, HCl being an example) reacts with an asymmetrically substituted alkene the hydrogen attaches itself to the carbon atom that has the larger number of its hydrogen atoms substituted. The halogen automatically attaches itself to the carbon atom having the least number of its hydrogens substituted. An example of such an addition reaction: Cl2HC=CH2Cl + HCl  Cl2H 2 C=CH2Cl2 Here the halide chlorine attached to the right hand side of the molecule that had fewer hydrogen atoms replaced. b.

The measurement given on the mass seems not to be accurate because the minimum measure of mass according to the apparatus is 0.0001, therefore if the measure was exactly 11.439 g then this should have been written as 11.4390 g. b) Volume of the gold cube 5.7 – 5.1 = 0.6ml c) Density and mass find volume of gold cube Density = Mass/Volume Volume =...

Explain the process of radioactive decay which takes place on (^14)(^6)C or what is known as carbon 14. A radio carbon such as carbon 14 will undergo a process of electron mission, therefore losing energy and moving ultimately to a place of chaos or entropy. The following formula will illustrate the radioactive beta decay which will act on carbon 14: ^14_6C------> ^14_7N+e 3). Utilize the S P D orbital system to describe Potassium.

...and cations can be varied to get the required end product. Ionic liquids have large anions and cations of low symmetry to reduce the lattice energy and reduce the melting point of the salts. Anions contribute towards the functions and chemistry of ILs and cations contribute towards the variable physical properties and stability of ILs (Bӧhme 2006). Ionic salts can be simple salts i.e. made up of one type of anion and cation or binary ionic liquids which are a mixture of two salts with varying melting points depending on their composition.

... of the of the pH Scale: pH stands for the power of hydrogen and is actually a measure of how acidic or basic a substance is. The pH scale measures the concentration of H+ ions in a solution The scale is divided into fourteen units with zero indicating the highest acidity while fourteen indicating the highest level of basicity. A solution or a substance having 7 pH is said to be neutral or having equal number of H+ and OH- ions. pH is calculated by taking the negative log of the concentration of H+ ions present in a solution. A 1 molar sulfuric acid has a pH of zero while caustic soda or concentrated sodium hydroxide has approximately 14 pH. Substances react differently depending on the pH they have.

This is due to reduced opposite charge potential between them that increase attraction. In C-N, C is partially negative while N is partially positive in charge because one electron is unbounded in C.
