Properties Of Chlorine Lab Report

b) Propane, leaking from a damaged tank, igniting easily is a chemical property because the propane changes into new substances when it undergoes this chemical reaction. Flammability describes the behaviour of a material when it is chemically changed,.

Add hydrochloric acid to the household product, and if the chemicals began to bubble, once mixed together, then this would indicate that sodium bicarbonate is present.

The composition of a pure substance is constant, and thus pure substances have characteristic physical properties that do not change and this is why we are able to separate each element in this lab experiment. Examples of physical properties that can be used to describe pure substances include solubility, conductivity, magnetism, density, boiling point, and melting point.

Sodium bicarbonate has a molar mass of 84.0 g/mol. It has a melting point of 50°C and can be an irritant.

Examine a piece of nichrome wire. On the data sheet, record the color and the luster of the metal. Use a forceps to hold the wire in the flame of your burner for about two minutes (recall where the hottest part of the flame is located). Describe the appearance of the wire while held in the hottest part of the flame. Allow the wire to cool and reexamine it. From your observations, determine if there was a physical or a chemical change. Give specific reasons for your conclusions. Save the nichrome wire for step #2.

If it is in contact with a liquid hydrocarbon, the water and the hydrocarbon form separate layers ... they are immiscible liquids. Water, being denser, will always be at the bottom. Bromine is actually more soluble in a hydrocarbon, so when shaken, it will switch to the top hydrocarbon layer, and changes colour from brown to purple. In an alkane (hexane is often used) the colour will change and switch layers, but it will remain co loured because no reaction occurs. In an alkene (e.g. hexene) the bromine tot;\Il)1 loses aU colour because an addition

The chemicals that Clorox bleach contains are water, sodium hypochlorite, sodium chloride, coco-betaine, fragrance, sodium carbonate, sodium chlorate, sodium hydroxide, sodium [olyacrylate, and sodium xylene sulfonate. Sodium hypochlorite has several short term potential health risks such as causing irritation and burns when in contact with skin, causing eye damage and irritation when in contact with eyes, irritating the nose, throat, and lungs upon inhalation, which can cause shortness of breath and pulmonary edema at higher exposures, and can also cause headache, dizziness, nausea, and vomiting. Chronic health effects include bronchitis after repeated exposure to inhalation. Fragrance can cause skin irritation, allergy, and has been linked to organ system toxicity. Sodium carbonate can be corrosive to the gastro intestinal tract if ingested. It can also cause blistering when in contact with skin and can be corrosive to eyes and cause conjuctival edema and corneal destruction. Sodium chlorate can irritate and burn skin and eyes, and can cause nausea, vomiting, and abdominal pain, as well as damage the kidneys and affect the liver. High levels of sodium chlorate can reduce the body’s ability to transport oxygen and at very high levels, exposure can lead to death. Sodium hydroxide is corrosive to skin and

3. The metallic atoms change from a liquid state to a gas state during the flame test. Is this a physical or a chemical change? Explain.

Purpose Statement: In this experiment, we will determine the chemical formula of an unknown hydrated copper chloride compound which is composed of copper and chlorine. We will use stoichiometry, which is the relationship between quantities of materials in a chemical reaction, to determine the chemical formula for a compound. We will use the mole to mole conversion to find the formula of a hydrated compound with the general formula CuxCly.zH2O. We will convert the masses of water, copper, and chlorine to moles of water, copper, chlorine and determine the whole number ratio of these components in the empirical formulas so we can find the empirical formula of the dehydrated compound, CuxCly and the empirical for the hydrated compound CuxCly.zH2O. Results:

The free radical chlorination of 1-chlorobutane resulted in a mixture of at least 4 different possible products from the reaction. Gas chromatography-mass spectrometry helped in figuring out which of the products are most abundant in the sample product created as well as in discovering the ratio of relative reactivities of the hydrogens. This experiment showed that the ratio of relative reactivities was found to be 1.0 : 3.5 : 6.2 : 2.4, which indicates that the secondary hydrogens are more reactive than the primary hydrogens and that reactivity further increases the further away the hydrogen is from the chlorine on the 1-chlorobutane. The results agree with the conjecture that the primary hydrogens are less reactive than

This scientific report is about how much mass is lost in metals after being placed in 1 molar hydrochloric acid for 30 minutes. Tin, iron and zinc will be weighed and placed into test tubes which will then be filled with 1 molar hydrochloric acid. After 30 minutes the metals will be taken out and weighed again. It is expected that the more reaction that occurs, the more mass is lost. Tin is a metal and has many uses and is commonly used to coat other metals to prevent them from corroding. An example of this is in tin cans made of tin-coated steel. Iron is another common metal which rusts easily but it is very important as it is used to manufacture steel. Zinc is a metal which is most commonly used to galvanise metals

Chlorine was first discovered by a man whose profession was in the medical field. However, since it was 1774, the technology wasn’t as advanced and therefore led him to misleading conclusions. Carl Wilhelm Sheele was a Swedish pharmacist who, “released a few drops of hydrochloric acid onto a piece of manganese dioxide in his lab, and a greenish-yellow gas was produced in a matter of seconds…” (Alchin, Linda. “The Element Chlorine.” What Is Chlorine?, www.elementalmatter.info/element-chlorine.htm.). Before Sir Humphry Davy, people thought that Chlorine was a form of oxygen. Sir Humphry Davy later proved otherwise. Although this element was never thought to be used this way, in World War I Chlorine was used as a “choking agent”. Men would suffer

The reason why titanium is very practical in such industries is that the equipment is in constant contact with corrosive materials. Titanium is mainly used in chemical applications that include heat exchangers, titanium anode, and titanium container. In the chemical industry, sodium carbonate is one of the major consumers of titanium. Furthermore, the paper industry uses titanium in the process equipment that is exposed to corrosive materials.

When water is in gaseous state, it can react with magnesium, aluminium, zinc and iron to form metal oxide and hydrogen gas. Mg(s) + H2O(g) → MgO(s) + H2 (g) Reaction with s-block metal hydrides: All s-block metal hydrides can react with water to form hydrides and hydrogen.

Chloride [11, 12] and sulfate ions are extremely aggressive media which can speed up the corrosion of metallic materials [13]. Asd (also called produced water or oilfield water)
