Sodium compounds

The goal of this laboratory experiment was to determine the identity of an unknown ionic compound, unknown sample 3, through the substance’s chemical properties and reactivity. This compound was discovered in a landfill and we needed to know as much information as we can about how the chemical will behave in different situations so that the city will not be negatively affected by the chemical.2 Thus, we first needed to identify the unknown substance, determine some of its chemical properties and…

prepare the absorbent, we will be using sodium alginate and calcium carbonate.1Sodium alginate is a common additive to foods, so there are several types. The type we will be using is called sodium;3,4,5,6-tetrahydroxy oxane-2-carboxylate. There are several sources to buy sodium alginate. However, we will buy it from Modernist Pantry, which the sodium alginate concentration has already been prepared. Before the preparation of calcium alginate itself, sodium alginate should be kept in a 39.2…

The objective of Chapter 6: Compounds and Elements was to determine how to synthesize and decompose pure substances, distinguish the difference between compounds and elements, and to determine the difference between complete and incomplete reactions. Previous chapters that contained valuable background knowledge were Chapter 2: Mass Changes in Closed Systems and Chapter 5: The Separation of Mixtures. The Law of Conservation of Mass, which was tested in Chapter 2, proved to be vital in this…

considered to be similar, as they are all white substances that are generally fine powder or small crystals. However, the lab revealed substances C: citric acid, D: sucrose, and H: benzoic acid to be covalent compounds, while the remaining substances to be all ionic. The previously stated covalent compounds all were found to have low relative melting points when heating them on a hot plate, but they had mixed results to their solubilities: citric acid and sucrose were found to be soluble in…

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…

“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…

The different chemicals that were used in this experiment were Pilocarpine, Atropine Sulfate, Epinephrine, Digitals, Potassium, Sodium, and calcium ion concertation. Pilocarpine stimulates the effect of parasympathetic nerve stimulation by enhancing acetylcholine release. Atropine Sulfate is a drug that blocks the effect of the neurotransmitter acetylcholine which is liberated by the parasympathetic nerve endings. Cardiac muscle and skeletal muscle are both different in functionally and in fine…
