Bicarbonate

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 that…

The Mystery Mixture (MM) is sodium bicarbonate and citric acid. I know this because when we started this lab we first observed the MM. It was clearly two powders, one was a fine white powder and the other one was more coarse. Next we added water to the MM and it started to fizz, it had a lot of large bubbles and as it continued to fizz there were more small bubbles. The next step was to look at the white powders that might be in the MM, the sodium bicarbonate was a fine white powder and the…

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…

thermal decomposition of sodium bicarbonate (NaHCO3). Since we were given four explanations, we had to use our knowledge and skillset in stoichiometry to complete the task. The first explanation stated that sodium bicarbonate, when heated, decomposes into sodium hydroxide and carbon dioxide. The second explanation was that when sodium bicarbonate is heated, it decomposes into sodium carbonate, carbon dioxide and water. A third explanation stated that when sodium bicarbonate is heated, it…

identities of two compounds isolated from an unknown mixture the process of liquid­­liquid extraction is used. Sodium bicarbonate is used to extract the aqueous layers first, followed by extraction with sodium hydroxide. In order for these compounds to precipitate HCL is used to acidify the solutions. The organic solvent will be extracted using NaCl and anhydrous sodium bicarbonate will be used to recrystallize it. Lastly, the mass and melting points of the two unknowns are measured to identify…

down by favorable for saline, sodium bicarbonate or inconclusive. The data from the articles closed was interpreted. Of the six articles chosen the data was sorted by conclusion and recommendations for safe pre-procedural care of predisposed patients. Of the six studies reviewed, one commonality the studies exhibited was intravenous hydration for at least 12 hours post procedure was the most efficient treatment for patients. Two studies listed Sodium Bicarbonate as more effective if given two to…

Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be…

of a leaf and placing them inside of a syringe with sodium bicarbonate buffer. We then pulled the plunger part of the syringe back which lets the bicarbonate solution infiltrate the air spaces in the piece of leaf. After the air spaces are completely infiltrated and the leaf discs sank to the bottom of the syringe we then placed the discs and the solution inside of that syringe into the beaker that was holding another 40 ml of bicarbonate solution. Then to test the actual…

and a carbohydrate.(Lab Manual) By manipulating the CO₂ concentrations, it was able to see how it directly affected the production of one of the products of photosynthesis, oxygen. It was hypothesized that increasing the concentration of sodium bicarbonate which was represented by CO₂ in the experiment will increase the rate of photosynthesis which will be determined by measuring the rate of oxygen…

reaction occurs when an unknown white powder is heated? #1: Sodium bicarbonate breaks down into sodium hydroxide and carbon dioxide. #2: Heating sodium bicarbonate produces sodium carbonate, carbon dioxide and water vapor. #3: Sodium bicarbonate decomposes into sodium oxide, carbon dioxide, and water vapor.
