Ion Essay Examples

This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity, then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any […]

Reductionism- Reducing complex systems to simpler components that are more manageable to study. Cells- The lowest level of structure capable of performing all the activities of life, all organisms are composed of cells which are the basic units of structure and function. The cell theory- The ability of cells to divide to form new cells […]

Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. […]

The lecturer handpicked the optimal data sets for comparing pH measurements of different soil types with and without 0.01M calcium chloride. Table 1 displays that sand exhibits the highest pH, followed by organic matter, compost, 3:2 soil, and sedentary soil with the lowest pH. Soil pH is impacted by acid and base-forming ions including hydrogen […]

Biohydrometallurgy is a mining application that utilizes biology to assist with metallurgy processes. The mineral chalcopyrite contains copper in its natural state, along with other elements. To obtain pure copper, a bacterium is used to create copper sulphate (CuSO4), which can then be chemically treated. This process of microbiological mining is utilized for low-grade ores […]

Isotopes, atoms with the same atomic number but different mass numbers, can be used in various ways such as radioactive tracing for thyroid and tumors. Radioisotopes, particularly gamma emitters with a short half life, are useful for detection without causing damage. Beta particle emitters are preferred over alpha particles because they penetrate more easily and […]

The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. ; Oxidation numbers are not real; they are only based on assumptions. They are useful bookkeeping tools though, and can help us keep track of electrons during a […]

Why Do Atoms React? Google Search 1. What is an atom? An atom is the basic unit of a chemical element. 2. What is an element? An element is a substance that is made entirely from one type of atom. 3. What makes an atom unstable (reactive)? The binding energy not being strong enough makes […]

A metal consists of a lattice of positive ions surrounded by a ‘sea’ of mobile ideological valence electrons. Metallic bonding is the electrostatic attraction between the ideological electrons and the positive ions in the metallic lattice. Properties of metals: Property Explanation Relatively high density The particles are very close together. This is because of high […]

Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Gel electrophoresis Is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson, we’ll review how agrees gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment. […]

In a redox reaction, one atom or molecule loses electrons while another gains electrons. In organic reactions, the gain or loss of electrons is not always clear. Consequently, organic chemists define redox in terms of the loss or gain of carbon-hydrogen bonds. Organic oxidation is defined as the loss of carbon-hydrogen bonds, while organic reduction […]

Define the following: electrolyte, nonelectrolyte Electrolyte: A substance that dissolves in water to form solutions that conduct electricity. Nonelectrolyte: A compound that doesn’t dissociate into ions when dissolved in water. Using examples in the last link, draw beakers showing atomic scale representations of aqueous solutions of the following compounds. Classify each as an electrolyte or […]

Phiten bracelets and necklaces have become very popular in the world of sports. The main sports they are used in is baseball and golf. At Phiten, they claim that their necklaces will “add energy” and “help people enhance their quality of life” (Hirata). The makers of Phiten say claim to use a special way of […]

he use of transition metal oxides, such as Co3O4, as positive electrode materials in lithium ion batteries (LIBs) has attracted great interest due to their high discharge-charge capacity. However, the poor capacity retention of the materials caused by large volume changes during the cycling process limits their cycle life time. Therefore I propose gold nanoparticles […]

This investigation will examine one of the factors that affect the amount off copper deposited during the electrolysis of copper (II) sulphate solution. Electrolysis is the decomposition of an ionic solution by electricity. The electricity splits ionic chemical compounds into separate components, for example, copper chloride can be split into Cu metal and Cl gas. […]

The purpose of this week’s lab is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this, two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure, the product must be precipitated out of the solution and then weighed. For this lab, lead (II) […]

A compound is a chemical substance composed of at least two elements with specific physical and chemical properties. It has a defined structure and cannot be separated by physical methods like boiling, freezing, sieving, or gravity thickening. When elements combine to form a compound, they lose their individual properties. Water (H2O) is an example of […]

LAB#: 20 SKILL: Planning and Designing OBSERVATIONS: A student is given a small beaker containing an unknown salt, x. The salt is crystalline, deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt […]

The objective of this lab was to determine the solubility of different solutions through a series of mixing and observation steps. The initial steps consisted of pouring the nitrate solutions into the designated sections of the 96-well plate. After completing this task, the sodium solutions were to be added to the specified sections of the […]
