    Sodium carbonate (molecular formula: Na2CO3), is the water soluble sodium salt of carbonate. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is

    Preparation Table(Table 1) and the Titration Table(Table 2). This was due to the initial production of the weight buret- the sodium thiosulfate solution and the dropping bottle- represented in Table 1 and the trials that occurred separately(Table 2). The initial mass of the solid sodium thiosulfate pentahydrate was 0.21 grams. Once the ten milliliters of water was added, the mass of the sodium thiosulfate solution as 9.70 grams(Table 1). In Table 2, the initial mass of the weight buret in trial one was 15.23

    The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder

    concentration of Sodium Chloride (NaCl) solution affects the volume of the gases (Oxygen gas and Chlorine gas) at the anode during the electrolysis of sodium chloride solution. In my previous chemistry classes, I have learnt that concentration affects the majority of the gas produced at the anode. This made me wonder, how does the ratio of oxygen gas to chlorine gas produced at the anode vary at the electrodes. This made me formulate the research question: How does the concentration of Sodium Chloride solution

    as alginic acid, sodium salt that is regularly called sodium alginate. It is a linear polysaccharide that typically isolated from numerous strains of marine brown seaweed and algae, in this manner the name is alginate. The copolymer comprises of two uronic acids which are D-mannuronic acid (M) and L-guluronic acid (G). That is because it is the skeletal component of the algae and it has the decent property of being strong but then flexible. The most ideal in preparation of sodium alginate is by adding

    Sodium bromide and 1-butanol are dissolved in water since the bromide ion from the sodium bromide and the four carbon chain from the 1-butanol are the desired components of 1-bromobutane. In order to get the sodium bromide and the 1-butanol to react sulfuric acid is added to react with the sodium bromide and combine with the sodium ion producing hydro-bromic acid. Later, when the flask is heated the bromide ion will be able to combine with the four carbon chain of the 1-butanol. During the process

    Sodium (Electrolyte) Balance – Physiologists often refer to sodium as the backbone of the extracellular fluid and emphasize that water follows sodium. Although separate hormonal axes exist for water and sodium reuptake, sodium plays a crucial role in maintaining intravascular fluid volume in addition to contributing to serum osmolality. As will be explained, the kidneys conserve much of the water (a.k.a. plasma volume) in the glomerular filtrate by retaining sodium. Serum sodium concentrations must

    alginate extraction, the acidified algal biomass was suspended in 3% Na2CO3 solution at different alkali: alga ratio (20, 40, and 60 mL/g). The different extraction temperatures ranged from 25 to 45º C, and lasted for 1 to 3 h. For each experimental run, sodium alginate was collected by filtration and precipitated with absolute ethanol (1:2 v/v). The mixture was maintained at 4º C overnight. The precipitate was collected by vacuum filtration and allowed to dry at room temperature. The crude alginate yield

    actual yield is 0.38 grams. So if 0.38 is divided by 0.49 and multiplied by 100 then the percent yield for Zinc Sulfide would be 77.6%. When it comes to Sodium Chloride, the theoretical yield is 0.58 grams and the actual yield is 0.45 grams. So when 0.45 grams is divided by 0.58 grams and multiplied by 100, the percent yield would be 77.5% of Sodium chloride. The actual yield is directly taken from the mass of the products in the experiment while the theoretical yield is determined by using stoichiometric

    4.B Why do you think that the adding of sodium acetoacetate resulted in a 50% decrease in renal ammonia production? Sodium acetoacetate addition would result in a decrease in renal ammonia production because of the adjustment to the pH levels that it has. This happens due to direct oxidation. Some of the dogs in this experiment became tolerant to the sodium acetoacetate so their doses were changed. The conclusion was that since quantities that were essentially equal in tolerance were given that direct
