Revision Central - GCSE Chemistry - Hard Water

http://www.revisioncentral.co.uk/gcse/chemistry/hard_water.html

Extractions: Hard water does not produce as much lather as soft water when it is used with soap and also an insoluble solid called scum is left on the sides of the wash basin. Calcium chloride, Magnesium nitrate, and Iron (II) Sulphate produce scum and no lather when contained in a sample of water that is mixed with soap. The ions that are responsible for "Hard Water" are therefore as follows: Hard water is formed by 2 main methods: H O (l) [In rain] + CO (g) [In air] > H CO (aq) [Carbonic Acid] This carbonic acid flows over chalk / limestone - reacts with calcium to form Calcium Hydrogen-carbonate. This is now soluble in water and so can cause hard water CaCO (s) + H CO (aq) > Ca(HCO (aq) [Calcium Hydrogen-carbonate]

Hard water. (chemistry). Things You Will Need Piece of chalk; Baseballsize stone; 3 jars; Handkerchief; Bottled water; Dish detergent; Spoon.
http://education.usace.army.mil/clubhouse/science/chemistry/hardwater.html

Extractions: Compare the amount of soap suds in each jar. What Should Have Happened The chalk water did not produce as much soap suds as the plain water. Certain materials such as limestone (the chalk) make water "hard." These materials do not mix well with the soap and do not lather very well. The name "hard water" originated during the Civil War. Soldiers found their beans were hard after cooked in water in certain areas. They then left behind signs reading "Hard Water" to warn other soldiers. Webdate: June 11, 2002

http://geoinfo.nmt.edu/labs/chemistry/watereval.html

Extractions: Water Quality Evaluation What do the results of my water analysis mean? All groundwaters contain various kinds and amounts of dissolved salts (sometimes called minerals). These salts originate from small amounts dissolved in rainwater from particles in the air and from the dissolution of soils and rocks as water moves through the ground. Small quantities of many salts are essential to good health and improve the taste of the water. Excessive amounts of some can be a nuisance, be corrosive to plumbing or even hazardous to health. When a well is drilled, a water analysis is generally carried out to determine if the dissolved salts exceed guideline or standard values. The term "potable" water refers to water that meets the U.S. Environmental Protection Agency (USEPA) standards for drinking water and includes physical, biological, inorganic, organic, and radiological parameters. However, unless there is a specific reason for believing well water to be contaminated, an analysis of the inorganic parameters (dissolved salts) is sufficient. Compare your well analysis to these limits . USEPA drinking water limits are shown as well as the NM standards for groundwater that is to be used for drinking water. Irrigation and livestock water are other uses that are listed. USEPA limits apply only to public drinking water supplies (a source that supplies 15 or more connections) and are listed here for comparison. A complete list of USEPA maximum contaminate levels (MCLs) may be found at

off) which can result in a perforated/melted anode and an Xray tube full of water!Last Updated August 13, 2003 - WebMaster URL http//www.chemistry.msu.edu
http://www.chemistry.msu.edu/Facilities/Crystallography/cs_Filter.shtml

Extractions: Crystallography Service The goal is to provide filtered house water to the three diffractometer heat exchangers ("A,B", "C" and "D") with sufficient flow to carry away the heat from the X-ray tubes. Clean water filters are essential to maintaining a constant source of X-rays for an experiment and to preserving the life of the X-ray tube and generator. Note the sequence of events: dirty water filters > reduced tap water flow through heat exchanger > reduced heat exchanger heat removing capacity > increased temperature of circulating water > circulating pump(s) stop > X-ray generator turned off. Recent experience indicates that the water filters last about 1 month with the refrigerated heat exchanger ("D") and a week or two with the ambient heat exchangers ("A,B", "C"). The filters are arranged in parallel with a pair of valves to isolate each one; the procedure for a pair of filters for a given heat exchanger is (starting with two new filters and all valves closed): open both valves for one filter allowing water to flow through only one filter after one week ("A,B", "C") or one month ("D") open both valves for the second filter allowing water to flow through both filters

water changes, chemistry of tap water and common treatment methods.
http://www.csd.net/~cgadd/aqua/art_chlorine.htm

Extractions: Jump to my non-fish home page The Danger Frequent weekly or bi-weekly water changes are an important part of keeping a fish tank healthy and stable. Over time waste products accumulate. And when water is lost to evaporation, the minerals and waste products are left behind, increasing their concentration over time. Also, the nitrification process (The filter converting ammonia into nitrite into nitrate) will slowly decrease the water's buffering capacity. If the buffering capacity is depleted, the pH can crash very quickly. Water changes help remove the bad stuff, and help replenish the tank water's buffering capacity. When adding tap water to a tank for water changes, several things should be done to make sure that you don't shock the fish. First of all, the temperature of the replacement water should be close the same temperature as the tank water. Second, and just as important: The water must be chemically safe for the fish.
Beginner FAQ: Water Chemistry
Beginner FAQ Practical water chemistry. What You Need to Know About waterchemistry, and Why. water Altering Your water s chemistry. Hardening
http://faq.thekrib.com/begin-chem.html

Extractions: Water in nature is rarely pure in the ``distilled water'' sense; it contains dissolved salts, buffers, nutrients, etc., with exact concentrations dependent on local conditions. Fish (and plants) have evolved over millions of years to the specific water conditions in their native habitats and may be unable to survive in significantly different environments. Beginners (especially the lazy) should take the easy approach of selecting fish whose needs match the qualities of their normal tap water. Alternatively, an advanced (and energetic!) aquarist can change the water characteristics to match the fish's needs, though doing so is almost always more difficult than first appears. In either case, you need to know enough about water chemistry to ensure that the water in your tank has the right properties for the fish you are keeping. Water has four measurable properties that are commonly used to characterize its chemistry. They are pH, buffering capacity, general hardness and salinity. In addition, there are several nutrients and trace elements. pH refers to water being either an acid, base, or neither (neutral). A pH of 7 is said to be neutral, a pH below 7 is ``acidic'' and a pH above 7 is ``basic'' or ``alkaline''. Like the Richter scale used to measure earthquakes, the pH scale is logarithmic. A pH of 5.5 is 10 times more acidic than water at a pH of 6.5. Thus, changing the pH by a small amount (suddenly) is more of a chemical change (and more stressful to fish!) than might first appear.
