Broken Glass Meter Lab Report

1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points)

Fire blankets are used to extinguish small fires. They are used by covering the small fires with the blankets until it extinguishes.

| Describe how the health and safety control equipment relevant to the work should be used in accordance with the given instructions.

1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points)

1. Gather appropriate lab equipment and secure a safe workspace with open ventilation, away from children and pets. All chemicals will be combined in the 96 well plate. Don’t contaminate end of pipet with other chemicals.

Head protection; wear a helmet to protect your head and prevent stuff from falling on to it.

Due to the microquantities being used, all chemicals will be disposed up with running water. Gloves, an apron, and splash goggles will be used to protect the eyes and skin.

When handling the Acid or Base to avoid getting any substance in eyes: Use protective eyewear

Before conducting the Activity Series Lab, participants must know how to protect themselves against the possible dangers that the hazardous materials from the lab can cause. Some of the things they must understand include proper safety precautions and how to protect against corrosive or poisonous materials. For instance, Copper (II) Chloride, one of the solutions used in the lab, can cause severe eye irritation. One way to protect against this is by wearing goggles, or other eye protection equipment. Another substance used in the lab is Silver Nitrate, a body tissue irritant. Participants must wash off the substance quickly if it comes into contact with their skin to prevent any serious damage. Not only is it vital to know how to be safe around the chemicals, but to fully understand the lab, participants must be able to recognize the clues to a chemical change.

Contact with any other chemical should be treated as this one. 8. All protective gear listed above should be used in the experiment in the same way. 9. Hair tied back.

Care should be taken when handling beakers, graduated cylinders, and any other glassware. It is also important to make sure beakers and graduated cylinders are not slippery, to prevent accidents. Since hydrochloric acid is harmful, even at low concentrations, glasses must be worn when using and handling it. Crystal violet also stains, so to avoid getting it on skin and clothing, gloves and an apron can be used if desired. Also be careful when pouring or using any of the chemicals, because they can cause irritation and can be harmful to skin and eyes.

First, record the mass of two 150 mL beakers. Proceed to obtain a sample of unknown 3 and place about 2.5 to 3.0 g of the unknown into beaker 1 and record the mass. Slowly add 50 mL of distilled water into the beaker while stirring the mixture with a stirring rod. Prepare for gravity filtration by placing a funnel in an iron ring attached on a ring stand. Next, begin to fold a piece of filter paper, tearing off the corner of the smaller segment of the paper, and placing it in the funnel.

D. Before using the glass electrodes, they must be washed in warm soapy water and put in the UV steriliser to ensure they are clean and free from bacteria. After the treatment they should be washed and wiped over with disinfectant and sterilised before being used again.

This experiment shall be repeated twice or more to enhance accuracy of the results obtained. Besides detecting systematic errors, this experiment would aid on the technique and understandings to the correct use of these equipments.

In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.
