Potassium sodium tartrate

K2CrO4 was added in Step 12 and this was what indicated whether or not the sample from Part B contained barium or not. The chloride ion in potassium chromate bound to the barium cation and formed a precipitate, if there were any calcium cations present, they would have stayed in the liquid solution. If the substance in Step 12 remained cloudy, it would have been a sign for a false positive. This…

How gunpowder changed warfare How gunpowder was invented is that some scientists in china were experimenting Saltpeter a powerful agent potassium nitrate. It was used in medical compounds for years until a man thought about mixing the potassium agent with sulfur and charcoal, it had a result of a mysterious powder. Some observers said that smoke and fire the scientist’s body parts were burnt and the houses that they were working at burnt down too. The powder was used by the reigning Sung…

unknown, we needed to have a set amount of the unknown salt, and then add measured amounts of water to determine the minimum amount needed to completely dissolve the salt. The cation test told whether the unknown contained barium, calcium, potassium, sodium, strontium, lithium, copper, or magnesium. Given a chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to…

1. In our notes, we reviewed the Major mineral: Sodium. We know from news and health professionals, our intake of sodium is well over recommendations for our bodies need. List three specific changes you could make to your diet to decrease your sodium intake. • Eat more fresh fruit and vegetables since they are low in sodium. I have also learned that canned and frozen fruits are also low in sodium. • When buying frozen vegetables I have learned that reading the label will help you to…

minutes which represented the dilution of bodily fluids by seeing the urine became clear and clear each time. For isotonic subjects, who consumed 1120mL of isotonic saline (0.9% NaCl), shown the importance of sodium related to normal body composition. For alkalosis subject, who consumed 100mL of sodium…

when I mixed solid sodium carbonate with hydrochloric acid, copper (II) sulphate solution with liquid sodium carbonate, and during the end of the change when I applied heat to sugar. The test of mixing sodium carbonate with hydrochloric acid was a chemical change because of a creation of gas and the state of the sodium carbonate changing during the process, meaning a chemical reaction must’ve took place. Afterwards, the examination of mixing copper sulphate solution with sodium carbonate was…

“With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2…

1-Paper 2-gallon size Zip- Loc bag 3-Iodine beads (available from forensic supply companies) Note: Iodine crystals can be used along with a small amount of powdered vermiculite. 4-Rubber or plastic gloves are recommended 5-Safety glasses or goggles Safety Precautions Firstly,Wear safety glasses or goggles to protect our eyes from iodine vapors. Iodine is very toxic in nature , both as vapor and through excessive skin contact. Work in a well ventilated area is necessary. We must Keep all…

Using qualitative analysis, two cations in an unknown solution was identified. After repeated mixing, centrifugation, and decanting, lead was confirmed in Part A and barium in Part B. In Part C, different colored flames of metal species were observed using cation flame tests. Formula unit, total ionic, and net ionic equations were then composed for the identified cations. If the experiment were to be repeated, step 13 could be ommitted as barium was already confirmed in step 12 with the…
