Ph Lab Experiment

Improved Essays
The learning objective of the experiment performed was to determine the pH of solutions that were given by using litmus paper and pH machine.

The Experiment was kind of successful except for an issue with one of the solutions. When we tried to figure out the pH by looking at the litmus paper; we were stuck between a pH of 6 and 7. The best choice was to choose a number in between 6 and 7. Based on the two methods used to find the pH the results were close to each other.

In this experiment we were given the choice to choose eight substances and figure out the pH of these substances. To figure out the pH of each substance we use pH paper and pH machine. Then we record the results of each substance. The reason that the results came out the way it did because procedures were follow right. When testing the substances the pH paper has indicators that help determine the color of the paper and in return the pH of the substance. The

A perfect example would be that plants can grow well depending on the pH contain in the soil. So the person that is growing these plants need to measure the pH of the soil before he or she starts to plant. These results shows that any beverage that is consume could be acidic, basic, and neutral. The measurement of pH is important in my life because when I use soap it should be a specific pH so my skin won’t be affected by it. I never realize how measurement of pH is important in people daily life.

The learning objective of the experiment performed was to balance a dilute solution of HCL with a dilute solution of NaOH.

In this experiment the pH machine was not functioning right so it affected the outcome of the pH reading for the solutions. In the beginning the pH machine was working fine; every time we added the NaOH into the HCL. As you can tell by the data it was after when 12 ml of NaOH was added that the machine started acting

    Start off by adding 10mL of H2O, 0.1 M NaCl, buffer with a high pH, and buffer with a low pH to separate test tubes. Pour 2mL of the red cabbage indicator to 4 test tubes or the use of a pH meter and record the value. Start by adding and measuring 5 drops of 0.1 M HCl solutions to each of the 4 test tubes from part one and mix. Find the value and record. Add 5 more drops of the HCl to each test tube from part 2 and mix.…

    Also, like the litmus paper, Multip-pH is a paper impregnated with an indicator solution. The paper is dipped in the solution and is matched with a pH color chart. Furthermore, if both pink and blue litmus paper fail to change color, than the solution is neutral. An example of a neutral solution would be distilled water, like mentioned before.…

    Materials. Numerous substances in the experiment were used. The most frequently used was the unknown due to the need to test its physical and chemical qualities. When a solution of the unknown was made, 1.000 g of the unknown and 1.0 mL of water was used to make it. To test for the possible ions, 1.0 mL of silver nitrate and 1.0 mL of nitric acid were used for the ion test.…

    In this experiment, identifying the acids, bases, or neutrality of the unknown substance in a specific set are used to find the actual substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver nitrate (AgNO3), Lead (II) nitrate (Pb(NO3)2), Hydrochloric acid (HCl), Ammonia (NH3), Water (H2O). From the substances above Hydrochloric acid (HCl) is the stronger acid, and Sulfuric acid (H2SO4) and Lead (II) nitrate (Pb(NO3)2 are the weaker acids. If the substance is not an acid nor a base, the substance is neutral. In each set there were three neutral compounds, one acid, and one…

    Throughout this acid, base and buffer lab, this will allow each individual to gain an enhanced sense of knowledge of how these different aqueous solutions work as a buffer system or how they are unable to perform as buffer system mixed with two solutions together. This can be identified through the colour change to measure pH behaviour in several aqueous solutions, therefore the different factors that will cause the change of pH. This will gain understanding of how this relates to the biological studies of biology and to the advantage of humans. Hydrochloric acid combined with water will not a make good buffer system. Hydrochloric acid is a strong acid that will not coexist with any other base in equilibrium.…

    Antacids are a class of medicine which assist to balance the acidity/ pH balance in your stomach. The pH system is a scale which measures how acidic a substance is or how basic a substance is or if a substance is neutralized. Antacids have the ability to give relief for heartburn, indigestion or symptoms of acid reflux. There are many types of antacids such as calcium, aluminum and magnesium. They’re many ways to consume antacids such as liquids, tablets and chewable tablets.…

    After thymol blue was added, the pH-buffered samples developed the colors of red, yellow, green, and blue as the pH of the solutions increased (Figure 3.1A). The pH-2 buffer turned to a light red-pink color, while pH-3 to pH-6 displayed very similar forms of rich yellow or light orange (Figure 3.1A). The neutral pH buffer solution appeared as a saffron green colored solution (Figure 3.1A). A mixture of yellow and green was apparent in the dijon color of the pH-8 buffer (Figure 3.1A). The buffer solution of pH-9 expressed a color that seemed to be a mixture of green and blue, reflecting a shade of marine blue (Figure 3.1A).…

    During the entire lab, the main purpose was to, Identify the given unknown salt through a variety of experiments which yielded valuable quantitative and qualitative data. Before any experiments were carried out, multiple properties were compiled in order to have a source to compare the found results with. Beginning with the first experiment to determine if the unknown salt was hygroscopic, efflorescent, deliquescent or none of the above properties. This test was done through weighing an amount of the salt and reweighing after 15 minutes which would show if the salt had one of the above properties (either by gaining mass from the air, losing mass to the air, turning to solution) or none of the properties. Furthermore, tests were done to identify…

    The measurement used for finding the pH was inaccurate and subjective because it was not an exact measurement. Colours look different to individuals. This could have been improved if a pH meter or something similar was used to measure the pH rather than a pH chart. The amount of time given for the reaction to occur may not be enough because some antacids may take longer to fully complete their reaction. The cleanliness of equipment used (e.g. test tube, spatula, glass rod) is important.…
