Topic: The reactivity series

Problem: Which of the following metals are more reactive with acids – magnesium, zinc, aluminum, iron, lead, and copper?

Hypothesis: Aluminum is the most reactive with acids because it occurs in group III.

Aim: To perform a comparative test on which metal is the most reactive with acids.

Experiment: A comparative test is done using time to find which metal has the fastest reaction

Skill: P & D

Apparatus : Equipment: 1. 6 beakers
2. Water
3. Measuring cylinder
4. Watch or Clock

Materials: 1. Aluminum foil
2.Copper coin
3.Lead pellets
4.Zinc from a battery
5. Magnesium from Antacid
6. Iron Shavings

Reagents: 1. HCl


Procedure: 1 Rinse the containers with distilled water.

2. Pour 25cm3 of HCl in each beaker by use of measuring cylinder.

3.Insert each of the different sample metals into a beaker one at a time.

4.Observe and record the amount of time before the reaction stops with clock.

5. Make a table of your observations.

6. Setup a control using water as the reagent.

Variables: Independent: Aluminum foil, Copper coin, lead pellets, Zinc from a battery,     
Magnesium from Antacid, and Iron Shavings.
Dependent: Reaction Time

Controlled: HCl

Control: This is an identical experiment using water as your reagent.

Data: The reaction time for the different metals , to show which is the most reactive in acids.
Metals     Reaction Time/seconds in acids.
Magnesium     
Aluminum     
Zinc     
Iron     
Copper     






Prediction: Aluminum will be the most reactive because it is in group 3 which has the least amount of electrons to loose.

Results: The results for reaction time of the different metals, to show which is the most reactive in acids.

Chemistry Lab: Molecular Formulas Essay - ... My third substance that I retrieved is Ethyl Methyl Ether which has a density of 0.7251 g/mL.(PubChem) Since the density is off 0.0599 g/mL I could eliminate it from density portion of the experiment. My fourth possible substance is 2-Hydroxypropan-2-Yl Radical with a density of 0.791 g/mL (GuideChem) just like 2-Propanol and also has a synonym of Isopropyl Alcohol (Usp) therefore; I will not eliminate it from density and keep It for further evaluation. My fifth substance is Propanol with a density of 0.804 g/mL (ChemBlink) which is 0.0208 g/mL more than my experimental value, since the difference is small; I will not eliminate it in the density and will keep it for further evaluation....   [tags: ChemBlink, ChemSpider and PubChem] 1406 words

Chemistry: Percent Composition Lab Introduction Essay - Percent Composition Lab Introduction The percentage of something is very important in everyday life. For example, a farmer would want to know the percentage of nutrients in a fertilizer they are using. In spring, the farmer may want to use a fertilizer that has a high percentage of nitrogen, because it "greens” plants. In the fall, the farmer may want to use a fertilizer that has a higher percentage of potassium, because it strengthens the root systems of plants. A way to find the percentage of nutrients is by using percent composition....   [tags: fertilizer, potassium, molar mass]

Washington, D.C.: The First Example of Urban Planning Essay examples - Washington, D.C. was the first capital in the world to be strategically chosen, designed and built. It was established by President George Washington. Washington was given this power to select a permanent capital under the terms of the Constitution (1787) and the Residence Act of 1790, which authorized him to pick an exact location for the country’s new, permanent capital city as well as to choose commissioners to plan and build it within ten years . The process of designing Washington is considered an example of what historic preservationists have defined as urban planning today....   [tags: process of designing Washington] 1459 words

Chemistry lab report Essays - The goal of the project was to characterize an "unknown" organic acid in order to make a proper identification of the acid, while learning proper techniques for scientific measurement and analysis of error. In order to ensure the most accurate data, a purification was performed by the process of recrystallization. To perform the recrystallization the powder was dissolved in a minimal amount of hot ethanol/H2O solvent that allowed the unknown powder to crystallize properly when cooled. This process allowed for the removal of soluble impurities when suction filtered....   [tags: Chemistry] 912 words

Acid-Base Chemistry Lab Essay - The purpose of this lab was to determine the pH and total acidity of grape juice and wine. A second purpose was to experimentally determine the pKa of a monoprotic weak acid, polyprotic weak acid, as well as, a free amino acid, alanine. Acids and bases were defined by Bronsted-Lowry in 1923, in which acids were described as substances capable of donating a proton and bases are substances capable of accepting a proton (Thompson and Dinh 2009). In addition to defining acids and bases, Bronsted-Lowry further classified acids and bases as being either strong or weak....   [tags: Scientific Research ]

Essay on Equilibrium Reaction Lab - IBDP Chemistry IA: Equilibrium Reaction Lab Introduction: Reactions are based on collisions of particles, in which the particles must have sufficient energy. Some chemical reactions are reversible, and when the rate of the forward reaction equals the rate of the reverse reaction, the process has reached equilibrium. As it will appear to have stopped, as there is no overall change due to the rates being equal. Through this lab, we will be investigating one factor that will affect the equilibrium constant....   [tags: Chemistry, Collision of Particles, Reactions]

Essay Nuclear Chemistry - Types of Radiation: • List the three types of Radiation and describe conditions under which each case occurs. Alpha, Beta, Gamma. Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged. The nuclei are ejected from heavy, unstable nuclei so as to remove excess protons and neutrons. However, the formed nuclei may still be radioactive in which even further decay will occur. Alpha emissions occur in nuclei with atomic numbers greater than 83....   [tags: Chemistry]

Organic Chemistry Essay - Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at first, then in Germany, later on in England....   [tags: Chemistry] 1119 words
