Lab Report Analysis Of Nahco3 And Alka Seltzer

The reaction "ICE" table demonstrates the method used in order to find the equilibrium concentrations of each species. The values that come directly from the experimental procedure are found in the shaded regions. From these values, the remainder of the table can be completed.

We took the plastic cup and added the stir bar into it, then we inserted the plastic cup and the stir bar into the styrofoam cup. Next, we secured the clamp on the ring stand rod, and then added the solution calorimeter to the other end of the clamp. Following that, we took the beaker and filled it with distilled water and transferred it to the graduated cylinder. Then we poured it into the plastic cup with the stir bar in it. We turned the stir plate to number 6 and let the water stir around for 10 seconds, then we added in our first effervescent tablet and let it for about a minute or until it was fully dissolved. We added an extra tablet to every test until we reached the total number of tablets we could insert which was 5. After we were finished with each test, we washed out plastic cup, the solution calorimeter, and the stir

Set up: Measure the amount of sodium hydrogen carbonate (2, 4, 6, 8, 10g) to be mixed with water in the beaker. This is the only independent variable in this experiment.

The mixture of sodium bicarbonate and sodium carbonate can be separated due to the different temperatures at which the carbonate and bicarbonate decompose. This separation is the focus of the experiment. The bicarbonate decomposes when heated by the Bunsen burner. The carbonate also will decompose but at a much higher temperature. So, when the bicarbonate is heated it decomposes into carbonate, and during the decomposition it releases water and carbon dioxide. Furthermore, the amount of water and carbon dioxide released can be found by finding the difference in mass of the original mixture (before heating) and the final mixture (after heating). The mass of the water and carbon dioxide can be used to find the percent composition of bicarbonate in the mixture.

mL cylinder to the beaker on the stir plate and empty it into the beaker. Place the pH probe in the beaker and record the pH in the data table. Drag the beaker to the red disposal bucket. Double-click the bottle of NaHCO3 to move it to the Stockroom counter. Repeat steps 5 and 6 for KNO3.

The mass of the CO2 in the Alka-Seltzer tablet could be found by subtracting the mass of the solution after the bubbles escaped from the cup form the mass of the all substance before the reaction. In each trial the amount of Acetic Acid (vinegar) was increased by 5 mL while still maintaining 35 mL of solution. Theoretical,the mass of the CO2 initially increases with the amount of vinegar used and then reaches a steady value at trial 5. This is because when the volume of vinegar exceeds 20 mL, sodium bicarbonate, which produces the CO2, became the limiting reactant and the same amount of CO2 is produced each time.

Alka-seltzer Lab Report Statement of the Problem: The question of this lab was to find the optimum amount of Alka-Seltzer and water to achieve the highest launch possible. As Alka-Seltzer can dissolve in H2O and release CO2g (carbon dioxide gas), the gas is trapped inside the container and starts to gain pressure. This is the combination produces Sodium Bicarbonate which releases CO2g and other products. When the pressure in the container reaches maximum pressure, the lid will pop off releasing the gas and making it fly upwards.

Write the equation for the dissolution of sodium carbonate in water as found in your laboratory guide.

An Alka Seltzer is a white, solid, odorless tablet that is used in our daily life. For the most part it is mainly used for temporary relief on heart burns, acid indigestion, upset stomachs, headaches and pain in general. The purpose of the lab conducted was to show the fastest way on can dissolve an alka seltzer tablet using different liquids. The liquids used were regular tap water, Sprite and Minute-Maid Apple Juice. So, if we use different types of liquids to see which will dissolve the alka seltzer the fastest, then out of the three liquids water will take the least amount of time to fully dissolve the tablet because it is the most recommended liquid to take with any

On Thursday August 27, 2015 my group comprised of Elizabeth Cruz, Samantha St. Martin and I initiated experiment. This was constructed of three Alka-Seltzer tablets and three beakers containing different liquids: water, salt water, and vinegar. The drive behind our experiment was to see what factors would make the Alka-Seltzer tablets dissolve faster. My group’s hypothesis was that the strong chemical compounds in vinegar will cause the Alka-Seltzer to dissolve faster and therefore take the shortest amount of time compared to the other mixtures.

First of all 0.25 g of NaHco3 powder is taken and poured into a beaker then water is added until it reaches 100ml. using a stirring rod the powder is dissolved in the water resulting in having 0.25% of NaHco3 solution. The solution is then poured into a measuring cylinder slowly so it won’t be more than 100cc. The plant is being held using a pipette which is filled with water at 0.98 cm3 max so it can help us see the change in volume because when bubbles are released from the plant they go all the way up to the pipette and every time they surface volume decreases because air replaces the water. The pipette itself is held by a Screw clamp on the Ring stand. The plant is submerged into the measuring cylinder which is filled with NaHco3 solution.

Stoichiometry and Chemical Reactions: Which Balanced Chemical Equation best represents the Thermal Decomposition of Sodium Bicarbonate? We were given four different balanced chemical equations that could explain how atoms are rearranged during the thermal decomposition of sodium bicarbonate,(NaHCO3). Our goal was to determine which equation best represents how atoms are rearranged during the thermal decomposition of sodium bicarbonate.

Add two milliliters of vinegar to the second beaker, three milliliters of vinegar to the third beaker, and four milliliters of vinegar to the fourth beaker. 7. Repeat these steps two more times for a second and third trial. Data & Results Section: Data Table with TITLE: The Effect Of Vinegar On Curd mass. Type of curd Trial 1: mass of curd (g) Trial 2: Mass of curd (g) Trial 3: mass of curd (g)

INTRODUCTION Atoms and molecules are always moving. When molecules move from high concentration to low it is referred as diffusion. Another type of diffusion is osmosis, a process in which water passes through a semipermeable membrane and it goes from low solute concentration to a high solute concentration (Diffusion and Osmosis). In both processes, they are both passive transport, a type of movement in which molecules move along a concentration gradient (Campbell, and Reece 130).
