Chlorides

The biology 151 lab groups at the University of North Dakota conducted an experiment to find out the effects of sodium chloride on the plants that are not naturally grown in salty soils. Wisconsin Fast Plants, which are naturally grown in low to no sodium chloride concentrated soils, were planted and grown in several different salt concentrations to discover whether the plants grew better or worse in given soil concentrations. After multiple measurements, the results came back that the plants do…

Introduction: Hot packs work by dissolving a salt, such as calcium chloride, in water to create an exothermic reaction. When salts are dissolved in water it requires energy to break their bonds apart, but energy is also released when the ions are surrounded by the water molecules. If more energy is released than is required to break the bonds, the reaction will be exothermic and will produce heat. In hot packs the water is kept separate from the salt, and when it needs to be activated, they are…

Dissolution test will be carried out in a simulated gastric fluid (SGF) using hydrochloride acid or a neutral buffer phosphate solution. The simulated gastric fluid without enzyme (SGF) at pH 1.2 and pH 3 containing sodium chloride and hydrochloric acid in 900ml deionized water will be prepared. Thus, the pH will be adjusted using hydrochloride(Ghazal et al., 2015). The simulated gastric media containing milk (whole milk, skimmed milk) will be prepared using an equal volume of milk and (SGF) pH…

Salts and molecules have different properties because salts are ionic compounds and molecules are covalent compounds. Justification: Salt is an ionic compound. An ionic compound is formed by ionic bonding between ions of opposite charge. Sodium Chloride and Potassium Bromide are both salts that have an ionic compound. Both elements have the properties of salts which include soluble in water, conductive, and a relatively high melting point. Molecules and Sugar molecules are covalent…

nitrate and 1.0 mL of nitric acid were used for the ion test. Ammonium chloride and calcium chloride were the two compounds that were tested on to see if either were the unknown compound. After obtaining a balanced chemical equation that would allow for the synthesis of calcium chloride, it was determined that 0.858 g of magnesium chloride and 0.902 g of calcium carbonate needed to be used in order for 1.000 g of calcium chloride to…

moles of water in the sample 0.148g C Mass of pure salt in the sample 2.342 g D Number of moles of salt in the sample 0.016g E molar ratio of water to salt in the sample 9.25 g 8. From your calculations, what is the empirical formula of magnesium chloride…

substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was silver chloride. Both reactions at station two did not react. Station three had a reaction occur between sodium carbonate and calcium sulfate forming sodium sulfate and…

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 Ag+ and Hg2+ are only moderately…

When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were added to both the unknown and known solutions. These…

When both solutions are mixed a white precipitate (Calcium Carbonate) is formed alongside Sodium Chloride. A clear colourless liquid is observed as the white precipitate is filtered through the filter paper.…
