Sodium bicarbonate

Each test yielded its own unique set of observations, calculations and results. In order to determine these various values through calculation, the experimental data as well as the chemical reaction of calcium hydroxide was used for all calculations. The chemical equation is displayed below: The first experiment determined the molarity of OH- and Ca2+, the Ksp and the ΔG for saturated calcium hydroxide at 21°C. In order to determine these values, the experimental data as well as the chemical…

For the following lab, the purpose is to utilize titration to determine the amount of ascorbic acid (vitamin C) present in a substance by reacting it with potassium bromate. An oxidation reaction takes place with ascorbic acid to produce dehydroascorbic acid, using an excess of bromine. The total amount of bromine utilized during the experiment is determined utilizing a back titration, in which the bromine is reacted with bromate. One mole of bromate produces three moles of bromine and the…

CONCLUSIONS: The purpose of this experiment was to find the concentration of the unknown base (NaOH) through a titration. In the experiment, it took 0.95 mL of NaOH with a concentration of 0.53 moles to neutralize 5.0 mL of a 0.100 M of HCl. In the expected result, the concentration of the NaOH was 0.50 moles. The percent error for the lab was only 6%, which means the lab had a fairly high accuracy. Differences between the expected results and the actual result would be caused by the sources of…

volume of NaOH used. The purpose of this experiment was to determine the [unknown acid] by titrating it with a standardized NaOH solution using phenolphthalein as the indicator. NaOH and the unknown acid HA react as shown in reaction below to form sodium salt and water: NaOH (aq)+HA(aq)→NaA(aq)+H_2…

Brugada syndrome. Another indicator of this disease would be that the electrocardiogram would show change occurring with the electrical activity of the heart and it will oftentimes be concealed. One way to fix the concealed ECG would be to conduct a sodium channel blocker. Studies were…

and 37% HCl solution (20 mL) to form 1.0 L solution. Both the stock solutions were sonicated to form clear solution. Cu2+ stock solution was prepared by adding water to a mixture of CuSO4·5H2O (5.0 g, 20 mmol), distilled water (700 mL), potassium sodium tartrate tetrahydrate (25 g, 89 mmol), and NaOH (7.0 g, 0.18 mol) to form 1.0 L…

taking his medications accordingly. Including the wife in the teaching each time is a priority because she is the only one he got, if she is not involved we may as well not teach the patient at all. A good method to use to teach concerning the low sodium diets teaching should start on admission. By asking the patient in plain language about his knowledge about a low salt diet and what would he choose on a regular day for breakfast lunch and dinner? To discover the attitude of the patient…

addition, the nurse will continue to assess for common signs and symptoms of hypervolemia or hypovolemia, potassium and sodium disturbances, and other electrolyte imbalances…

light, water, and carbon dioxide and the removal of oxygen. Sodium bicarbonate is added as the bicarbonate ion acts as a carbon source for photosynthesis. Light independent reactions are catalyzed through the power of enzymes and are dependent upon temperature. Metabolism is linked to temperature; therefore metabolism will be affected by varying temperatures (Guy and Robert, 1985). Furthermore, we hypothesize that the chilled sodium bicarbonate will slow down both the rates of photosynthesis and…

Based on the results of the control experiments, the interaction between the Calcium Chloride and phenol red are responsible for the high temperature change in the overall reaction. After doing a control experiment with Sodium Bicarbonate and phenol red and noticing that the temperature got colder, only one other chemical mixed with phenol red could be responsible for the warm temperature change that chemical being Calcium Chloride. There was a temperature change that was observed during the…
