Sodium chloride

To begin, we put 200mL of water with one drop of green food coloring into a pie tin. We then mounted the short candle into the clay in the center of the pie tin. After, we lit the candle, waited approximately five seconds and bottled the candle. Lastly, we waited for the flame to go out and measured how high the water rose in the bottle. This process was repeated for the medium and tall candle as well. Data Table: Height of Candle Height Water Rose in Bottle Short 4cm Medium 4cm Tall 4cm…

In this lab, the percent composition of each component in the mixture was calculated. The mixture contained NaCO, CaCO3, and sand. NaCO or salt had a physical change when it completely dissolved in water. A chemical change occurred when hydrochloric acid was added to CaCO3 or chalk because the mixture changed to a yellow green color. In order to obtain the percent composition, a filtration system was used to separate the sand from the liquid, by straining the solid with the use of filter paper.…

Salt use on roads in winter salt is a common way to clear slippery roads. Salt lowers the temperature of the water which causes it to melt and it's one of the effective way of lower weather related collision. Using salt on road lower car accidents on highway up to 80%. However, salt used on roads causes rust on cars and environmental studies had showed that salt use for de-icing could affect water supplies, soil,and wildlife. Negative effect of using road salt The more salt that gets into…

cations of cupric nitrate, ammonium nitrate, zinc nitrate, calcium nitrate, aluminum nitrate, silver nitrate, ferric nitrate, and plumbous nitrate. The other seven solutions should be the anions of sodium hydroxide, sodium carbonate, potassium sulfate, sodium iodide, sodium phosphate, sodium chloride, and sodium chromate. Divide students into groups of two. Provide a bin of paper towels for the students to empty their well plates. Students: Obtain a pair of safety goggles from the goggle…

The chloride test resulted in no evidence of a white precipitate, which pushed the team to conduct the sulfate test. During the sulfate test, the solution became cloudy, the unknown substance did not completely dissolve, and there was evidence of a white precipitate…

In this experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any…

to see if the combination and specific concentrations of sodium thiosulfate plus sodium hypochlorite are able to produce second degree burns on a person within 10 seconds. In order for a second degree burn to be possible we must reach a temperature of at least 56°C (133°F) in order to create burns up to third degree for the time the chemical stayed on the worker. Now the dumpster contained 6% mass sodium hypochlorite and 20.0% mass of sodium thiosulfate. Which when we calculate the molarity of…

Salt is a unique yet very flexible substance that the earth and most inhabitants need to survive. Since early times it has been a key part of a social and cultural aspects of life. salt is even used in the bible to state the importance of the human creation from the heavenly father. Make your bed - “you search for something that can give you solace, that can motivate you to begin your day, that can be a sense of pride in ugly times.” Refer the bible with salt and the lord gives salt the ultimate…

spillage had not been quantified at the time of reporting, however, speculations indicated that the spillage could have been serious, thus detrimental to the environment and a threat to environmental well-being. CSX went ahead to confirm the leakage of sodium hydroxide from a derailed tanker car…
