Sodium chloride

attracted to the oxygen (negative) end of the water molecules, and the negative Cl- ions were attracted to the hydrogen (positive) end of the water molecules. As an end result, the ionic bond between the sodium and the chloride was broken. CuSO4(s) ⇔ Cu+2(aq) + SO4-2(aq) Like the sodium chloride, the copper sulphate was split into its individual ionic components. The positive Cu+2 ions were attracted to the oxygen (negative) end of the water molecules, and the negative SO4-2 ions were…

is more efficient. It is then extracted using dichloromethane (DCM) and maceration. The chlorophyll and β-carotene pigments are dissolved into the organic DCM layer which is polar and does not mix with water. The solution is then washed with sodium chloride (NaCl) to draw out any remaining water left in the solution that was not dried out by the ethanol. [1] Water will move toward the more hypertonic solution and separate from the DCM extract. After successful separation of the pigments from the…

all the compounds given to us in the reference material (Figure 1.2) but we could just compare the results. General Solubility Guidelines of Ionic Compounds in Water SOLUBLE COMPOUNDS EXCEPTIONS Almost all sodium (Na+ ), potassium (K+), and ammonium (NH4+ ) salts All chlorides (Cl- ), bromides (Br- ), iodides (I-) Ag+ , Hg2+ , Pb2+ All fluorides (F- ) Mg2+ , Ca2+ , Sr2+ , Ba2+ ,Pb2+ All nitrates (NO3- ), chlorates (ClO3- ), perchlorates (ClO4-), and acetates (CH3COO- ) Acetates of…

Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism. Background: When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles.…

and based on the wavelength of the photon, a different color will be produced when the compound is burned 3(Gilbert, Kirss, Foster, & Davies, 2014). The test of the unknown compound produced an orange color. An orange color shows the presence of sodium ions 4("Metal Ion Flame Test Colours Chart," 2014). But the color also could have been no color which means magnesium ions are present 4("Metal Ion Flame Test Colours Chart," 2014). Because this color was too close to the original flame color, so…

intermix in an aqueous solution.3 Some reactions vary based on temperature or solute concentration. The determination of precipitates also come from solubility rules. According to Cooper, almost all sodium, potassium, and ammonium salts are soluble which mean that they will not form a precipitate.1 All chlorides, bromides, iodides, and fluorides, nitrates, chlorates, perchlorates, and acetates, and sulfates are also soluble. The only exceptions are as follows: Ag+, Hg2+, Pb2+, Mg2+, Ca2+, Sr2+,…

compound with sulfuric acid (H2SO4) produced no visible reaction (precipitate), although the pH of the resulting solution was very acidic. Combining the unknown compound with sodium hydroxide (NaOH), a strong base, also had no visible reaction. However, the resulting solution was a lot more basic. Reacting the unknown compound with sodium nitrate (NaNO3), a salt, did not have a visible reaction nor did the pH of the resulting solution change. The last reaction involved the unknown compound and…

INVESTING DIFFUSION THROUGH LIVING MEMBRANES Introduction Cells are living membranes. They are the basic unit of life. They are very unique in that they have the capability of carrying out a large number of chemical reactions in the body, ability to respond to stimuli, capable of producing more of themselves, they have a genetic program and the means to use it, they acquire energy and utilize it, all in the process of the functioning of the human body, The life of a cell is also dependent on…

This scientific experiment will entail the rate at which ice will melt with different types of salts that include, table salt, sea salt, and rock salt. Salt melts ice essentially because adding salt lowers the freezing point of water. Although we know that salt has the ability to melt ice, we are testing whether sea salt, table salt, or rock salt melts ice more efficiently by calculating the amount of time it takes to melt the ice. We will begin by placing the same quantity of each type of…
