Excerpts
Lead-free metal team is in the use of a very active, particularly in industrial and in daily life if this substance in the body will cause chronic toxicity and may die from the study found that.In the study a framework science.The process for education as follows: 1.Preparing NaOH solution, and reduce (II) 41.75 G nitrate dissolved in distilled water to a volume 500 ml. Bottle measure capacity which will be reduced (II) nitrate concentration is 0.25 mol/L NaOH solution and prepare potassium it ไดด์ 41.5 G distilled water 500 ml until there is capacity.In the bottles measure capacity which will be potassium the video ไดด์ that is the concentration 0.25 mol/L 2. Shell the mangosteen to weigh up to 200 grams, and then used to beat it in a mortar, and then blend in a blender, put the water juice 400 ml. and then put in a dozen glass 3.The Tattoo sounded, and reduce (II) nitrate Concentration is 0.25 mol/L, and put it in a 20 ml beaker beaker beaker 6 4. Use a tube inject nozzle juice from the mangosteen shell, and put it in a beaker beaker beaker 6 0.5 ml., 1 ml, 5 ml, 10 ml and 20 ml, respectively 5.Enter the video ไดด์ potassium that is the intensity 0.25 mol/L in each beaker beaker beaker 5 0.5 ml. 6. Use of glass block, terminal, terminal, set aside 6 hours of research, we found that we were going to be able to conclude that the concentration 0.01 formation of reduced (II), nitrate (mol/L) will start to have more substance and more sediment reduction (II) nitrate much more passengers will be the color of dark, and the height of the sludge will be only more
