Zip Lock Lab Report

The experiment is to observe a variety of chemical reactions and to identify patterns in

If the 0.2 g, 0.4 g, 0.6 g, 0.8 g, or 1 g (±0.1) of baking soda used in this experiment increases, then the volume (mL) (±0.5) of the carbon dioxide released from the decomposition will also increase.

You know what color phenolphthalein and BTB turn when testing an acid or a base. Use three household cleaning products with BTB. Name the items tested and their results:

When using the 6.56g of baking soda and 26mL of Hydrochloric acid the bag inflated too quickly and too much and the bag popped and released all the gas through the top. Our third and final trial of 5.15g of baking soda and 20mL of Hydrochloric acid the bag inflated in about one second and inflated to just the right amount where the bag was not too hard and not too soft.

A sample of gas is trapped in a sealed container, which has a movable lid. Moving the lid up or down will change the volume inside the container. You will use an attached manometer to measure the pressure inside the container.

In this experiment you will observe some physical and some chemical changes. You will observe that energy must be used to start some chemical reactions, and that it is produced in others.

Purpose: The purpose of this lab activity is to help understand observation and interpretation and to distinguish one from another all while analyzing the chemical reaction. You will see what happens when you put a beaker with water in it and then put dry copper and after that put aluminum foil in and see the observations and interpretation in the chemical reaction.

4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.

Next, add concentrated HCl drop wise until the litmus paper indicates that it is acidic. During this procedure, I added to much HCl because many CO2 gas bubbles evolved. This error in the experiment will cause the recovery % to be lower.

After we had the balloons with filled with 10mL of vinegar each, we attached them to the baking soda test tubes. After all the components had been situated, we carefully lifted each balloon to pour the vinegar in. We made sure to closely compare which balloons had inflated more than others, and to see if any baking soda was left behind. A good technique to utilize would be to take pictures of the results; a technique that my group could have benefited from should we have used

The purpose of this lab is to decipher and observe the four types of reactions.

For my procedure, I will put the filter paper in each of the chambers. Then, I will use the dropper to put a small amount of acid on one of the pieces of filter paper, and will do the same with water on the other side. Then, I will place 5 pillbugs on each side of the choice chambers, and I will set the timer to 10 minutes and record how many bugs are on each side every 30 seconds.

This experiment is an experiment because of the reactants, and it is has to do with a process called

Add 4 drops of phenolphthalein in to the prepared acetic acid, and check whether the color changes to dark pink.

Obtain 0.020 M of Formic Acid (HCCOOH). Calibrate the pH meter using the instructions for calibrating the pH meter in the appendix. After the calibration of the pH meter, 150 mL of Formic acid solution was dispensed into a clean dry beaker, and then 50 mL of the formic acid was transferred into a 250mL beaker.
