Positive And Negative Conduct Electricity
595 wordsElectrolytes are liquids that conduct electricity. Most need to be dissolved into water or another solvent. Battery's have an electrolyte in them, either as a liquid or as a paste. Liquid electrolytes are used in electrolysis, electroplating, and other chemical processes. When electrolytes dissolve they release positive and negative ions. The released ions carry electric charges between electrodes, in the solution. Cations (a positively charged ion that migrates to the cathode, a negative electr...

Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

Waste Disposal Metal Ions
709 wordsQualitative Analysis of The purpose of this experiment is to demonstrate the separation and identification of metal ions based on the insolubility of certain salts. The solubility rules should be taken into account. If a solution dissolves in water, the result contains both cations and anions. Analyzing different ions to discover their nature is the main goal of this experiment. Separation of the cations by testing the differences in solubility of different metal salts is done. Also, identificat...

A Summary Ion Channels In The Membrane
869 wordsA Summary: Ion Channels in the Nerve-Cell Membrane In this article, Richard D. Keynes details the workings of ion channels in nerve cell membranes. Nerve impulses (action potentials) are the unit by which information travels in an organisms nervous system, and the generation of this action potential is dependent on the nerve membrane being permeable to ions which in turn makes said membrane excitable. Electrical activity of a nerve is triggered by a depolarization across the membrane and this al...

One Of The Most Important Hydrogen Ions
1,103 wordsIn this highly technological world with advanced machines, electronics have been woven into almost every aspect of everyday life. Batteries are integrated into the majority of any electric appliance found in the home and work place, and therefore could be titled as one of the most important tools to ever be invented. The knowledge of how batteries operate is substantial to understanding the basics of any electrical contraption. The first evidence of batteries was dated to be from in the neighbor...

Atomic Absorption Spectrophotometry Parts Per Million Water
1,290 wordsThe purpose of this experiment is to explore the hardness of the water on campus. Hard water has been a problem for hundreds of years. One of the earliest references to the hardness or softness of water is in Hippocrates discourse on water quality in Fifth century B. C. Hard water causes many problems in both in the household and in the industrial world. One of the largest problems with hard water is that it tends to leave a residue when it evaporates. Aside from being aesthetically unpleasing t...

Active Transport Membrane Potential
2,258 wordsEffects Of Solutions On Ion Transport Across Membranes Abstract Concentration gradients exist between two different salt molarity solutions on opposite sides of a membrane. Movement of ions across these sides can be achieved by either active or passive diffusion. In our first three experiments we used these concentration gradients to determine the characteristics of selective permeability of an artificial membrane to potassium chloride (KCl), the potential difference across the skin of a frog, R...

Metal Ions Drinking Water
2,316 wordsWater is a tasteless odorless vital element in which 90 percent of all organisms depend on to survive. It is one of the best-known ionizing agents and, is frequently called the universal solvent. Water combines with certain salts to form hydrates. It reacts with metal oxides to form acids and it also acts as a catalyst in many important chemical reactions. Not only is it essential to our health, but it is also crucial in the household and the industrial world. Every day we use water for cooking,...

Positively Charged Positive Charge
1,691 wordsLightning is a discharge of static electricity in the atmosphere, which causes a bright flash of light. When lighting goes through the air, it heats the air to degrees hotter than the suns surface about 50, 000 degrees fahrenheit. This heating causes the air to expand and contract. This causes the sound called thunder. Lightning is caused by a build up of negative ions in the atmosphere which discharges into the ground causing the negative ions to go with the positive ions in the ground. Static ...

Test Tube First Four
2,315 wordsIntroduction: Qualitative Qualitative Analysis Qualitative Analysis Introduction: Qualitative analysis is used in the determination of the identity of a substance. It is different from quantitative analysis, which deals with the determination of the amount of a substance. In this experiment, qualitative analysis techniques are used to determine whether or not a sample contains a certain ion. When using this method, an unknown and a reactant are mixed. The result of the reaction leads to a conclu...
