Sodium Bicarbonate is an electrolyte that can be used to treat dehydration, but its main use is to lower the PH of the blood. Before insulin and saline, Sodium bicarbonate was used to help treat diabetes. It can also be used to treat upset stomach or ulcer diseases because it neutralizes…
Sodium hypochlorite (bleach solution) is used to kill remaning organisms in the water grom the final settling tanks. The second stage is water DE chlorination, this is where chemical (sodium bisulfite) is used to neutralize the bleach prior to the clean water discharge.…
Calcium Carbonate is found naturally in food products. It is needed for everyday, common body activities. Calcium Carbonate is used to prevent Calcium deficiencies. Some common names for Calcium Carbonate in the medical industry are Tums, Alka-Mints, and Maalox. Calcium Carbonate has other uses besides medical purposes, such as building materials and construction, and paper, plastics, paints, and coatings. You can also find it in chalk, limestone, and marble. Calcium Carbonate is able to be extracted from marble in a pure form. It is also able to be prepared when Carbon Dioxide is put through Calcium…
Given the mass of NaCl we can easily calculate moles using the fence method. First find the mass of one mole of NaCl, which is equal to 58.44 g. Then take the amount of moles you have been given, 1.7, and divide that by 58.44 g. The total number of moles in this problem is 0.03 moles. Given the mL of solution we can easily calculate liters, again using the fence method. Take the amount of mL given and use a conversion factor of 1 mL/1000 L to calculate that there is 0.75 liters in the final solution. To find Molarity you divide 0.03 moles/ 0.75 liters to end up with 0.04 Molarity.…

hydrogen chloride has properties: Hydrogen chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because the smaller the chain of the molecules are then the energy required in small quantities however if the chain is long then it will need more energy so that means that the longer chain will have a slow reaction and the longer the chain the chances…
Sodium hypochlorite, also known as chlorine bleach, soda bleach, or household bleach is a chemical with the formula NaClO. A common way sodium hypochlorite gets into the San Francisco bay is through daily household cleaning products such as laundry bleach. In a survey conducted by The Clorox Company, it was found that four out of five households use sodium hypochlorite bleach for their laundry. Since laundry detergent companies are not required to list every ingredient, customers are often not aware that they are purchasing harmful chemicals. When the run off from used laundry water gets into the bay, it becomes filled with toxic chemical pollutants such as sodium hypochlorite. The bay water is the primary water source for bay plants. If the water they are receiving contains Sodium Hypochlorite, this could affect the plant’s growth. Water treatment plants use industrial strength sodium hypochlorite. Although the water treatment facilities try to remove it from the water before it gets released back into nature, the data from Don Edwards San Francisco Bay National Wildlife Refuge found that there is still an average of .6 to…

Chloroform is a halogenated organic compound known by its nonsystematic name. The chemical name for chloroform is trichloromethane. The molecular formula of this synthetic chemical is CHCl3. A particular odor, considered by some to be pleasant, will let one know chloroform is in the room. Because without it, the lack of color of this clear liquid makes it difficult to identify. Be fair warned: trichloromethane is volatile. It also sinks in water because it is denser. Chloroform is nonflammable under most conditions. The chlorine atoms in trichloromethane are more electronegative than the carbon atom, which is to say that the electrons are more greatly attracted to the chlorine atoms. Consequently, the chlorine has a partial negative…
Also known as "benzoate of soda," sodium benzoate is an FDA-approved, polyunsaturated fat that has been used by food manufacturers for over 80 years to inhibit microbial growth. As a food additive it is used as a preservative, effectively killing most yeasts, bacteria and fungi. Sodium benzoate is effective only in acidic conditions (pH < 3.6) making its use most prevalent in foods such as preserves, salad dressings (vinegar), carbonated drinks (carbonic acid), jams (citric acid), fruit juices (citric acid), and chinese food sauces. It is also found in alcohol-based mouthwash and silver polish. More recently, sodium benzoate has become apparent in many soft drinks, including Sprite, Fanta, Sunkist, Dr Pepper and Coke Zero.…
In my experiment I have found that 50 millilitres of HCL with 2 grams of sodium chloride had the highest conductivity rate compared to the second most conductive solution, 50 milliliters of vinegar with 2 grams of sodium chloride, and the last conductive solution, 50 milliliters of distilled water with 2 grams of sodium chloride. In my first hypothesis I stated if I added sodium chloride to distilled water, than the overall conductivity will become more conductive than just distilled water, since the sodium chloride will break down into it’s respective ions. I also noted the solution will however be less conductive compared to vinegar and HCL also encompassed in 2 grams of sodium chloride. Judging by my final results and several attempts, I…
IUA-,TERIAL S AND E QUI PME NT Solids: Reagent Grade potassium chlorate (KC1O3)and potassium chloride (KCl). Solutions: dilute (6 M) nitric acid (HNO3) and 0.1M silvernitrate (AgNO3). Th.o No.0 crucibles with covers; Ceramfab pad. DISCUSSION The percentage composition of a compound is the percentage by mass of each element in the compound. If the formula of a compound is known, the percentage composition can be calculated from the molar mass and the total mass of each element in the compound. The molar mass of a compound is determined by adding up the atomic masses of all the atoms making up the formula. The total mass of an element in a compound is determined by multiplying the atomic mass of that element by the number of atoms of that element in the formula. The percentage of each element is then calculated by dividing its total mass in the compound by the molar mass of the compound and multiplying by 100. The percentage composition of many compounds may be directly determined or verified by experimental methods. In this experiment the percentage composition of potassium chlorate will be determined both experimentally and from the formula. When potassium chlorate is heated to high temperatures (above 400'C) it decomposes poto tassium chloride and elemental oxygen, according to the following equation: 2 KCIOB(s) -----+ 2 KCI(s) + 3 Ork) The relative amounts of oxygen and potassium chloride are measured by heating a weighed sample of potassium chlorate and determining the amount of residue (potassium chloride) remaining. The decrease in mass brought about by heating represents the amount of oxygen originally present in the sample. From the experiment we obtain the following three values: 1. Mass of original sample (KCIO3). 2. Mass lost when sample was heated (Oxygen). 3. Mass of residue (KCI). From these experimental values (and a table of atomic masses) we can calculate the following: 4. Percentage oxygen in sample…
