Use the Internet to look up the SDS for hydrochloric acid and answer the following When these two chemicals react, hydrogen gas is released into the air, which is very flammable. Safety Information. Hydrochloric acid in its concentrated, liquid form has a strong irritating odor and is very corrosive. 2 0 obj Note that many chemical mixtures produce toxic or flammable gases. Identify 3 chemicals that produce a potentially dangerous reaction with hydrochloric acid. Household items can be very dangerous if they are mixed with other chemicals in your house. This is because some reactants can be very dangerous chemicals released into the air, while other reactions are exothermic and will begin to heat up to very high temperatures. Data Table 3: Part 1 and Part 2 of the Safety Contract. Skin: severe burns and ulceration %äüöß List 5 precautions that must be taken before beginning an experiment. 2.

According to Ward’s Natural Science, aluminum’s metallic powder will react very dangerously when combined with acids. Bleach is one of the most reactive and dangerous chemicals to mix with anything. unconditionally accept full and complete responsibility for any and all liability related to my Home ( My Account (, Contact Us ( Logout ( Hydrochloric Acid . In the lab, avoid mixing chemicals near burners. They react very violently and will cause chemical burns. This question focuses on Learning Objective 3: Describe various forms and uses of safety. Acid rain is a man-made calamity. If bleach is mixed with the slightest amount of ammonia, a very toxic and dangerous fume will be let off into the air. It could be hazardous to bleach with anything within our house, because we may never know the ingredients of our household products. Magnesium metal reacts violently with many other compounds as well. reaction can occur. emergency situation, Provides chemical, physical, health, preferred method. The reaction is dangerous and almost unstoppable, because it cannot be smothered (because it provides its own oxygen) and it cannot be put out with water (burns wet). Bleach can be poured If the concentration is high enough, it can cause chemical burns and put holes through cloth. Please sign in or register to post comments. FEEDBACK exposed to heat source. a. Chemistry can be very amusing, but when combining different elements, it is very important to be cautious and know what will happen. experimentation section once you click “Submit Your Data” below. The sulfur dioxide, which is formed by burning coal and oil, goes up and mixes with the clouds. experimentation; I will always experiment in a safe and prudent manner; and I f. Describe how to handle small spills. So, it is always advantageous to know the most harmful reactions in the field of chemistry. For the most part, items in the lab kit are safe for use around children and pets. ACGIH TLV = 5 ppm (7.59 mg/m 3) TWA NIOSH IDLH = 50 ppm (as HCl, 2010) Exposure Controls: Eye Protection: Tightly fitting safety goggles. immerse the contaminated equipment in pure bleach.

If the concentration is high enough, it can cause chemical burns and put holes through cloth. Household items can be very dangerous if they are mixed with other chemicals in your house. also cause corrosion and permanent tissue damage to the esophagus and digestive tract When dilute hydrochloric acid is used, gas spontaneously flammable in air is evolved. You will NOT be able to change your answers in the Therefore, mixing these two chemicals is considered a fire hazard. Therefore, you should always be careful when making chemical reactions 1. <> He has written several articles for eHow and holds a Master of Arts in creative writing from Oregon State University. No. contamination. and safety information regarding running water. Turn in the Final Report using your instructor’s Categorize each statement as true or false. It is a very reactive ingredient that will explode very easily. If any chemical in the kit has been ingested, you should _____. absorbent, Absorb spill using an Rise mouth Do not induce vomiting drink sips of water and seek medical attention immediately. 2��6<4��t��ui����L�����l̃ e8cY�c�5!��1!+P1�"K������.
