Reactivity of Metals

Sodium


Calcium
Lithium



Start color for all elements
All elements total 






Aluminum and Magnesium

Analysis- From this lab I learned that different elements have different reactions when placed in an acidic solution. Sodium and Lithium reacted the fastest quickly changing the color from an acid which is red to a base which is the color blue. The other 2 elements, Magnesium and Calcium took much longer but eventually turned the red liquid to blue. Aluminum never turned from red to blue.  What causes this reaction is when an element is placed in the acidic solution causing it to loose one of its valence electrons.

What went wrong- first the lab took a very long time to actually record all the results a total of three days. Second the lab was very dangerous. Third there was unmeasured amounts of each element throwing off some of the accuracy.

Today in chemistry, we used pennies, a vinegar-water-salt solution, matboard to construct a battery to power an LED light. We started by first collecting five pennies and shaved the copper off of the tails side. We then created a vinegar/salt solution in which we dipped the matboard into. To construct our battery, we would place a penny shaved side up, then place a soaked piece of matboard on top of it. Finally we placed an unshaven intact penny at the top of the stack and place an LED on each end of our battery. Our end result lit up, causing us to then question the factors that caused this. for example, we placed more pennies onto the battery which ultimately made the LED light up brighter. In this lab I think that the solution soaked onto the matboard was a source of chemical energy and conductivity through acetic acid, sodium, chloride, and water, which was converted into an electrical current and passed through the pennies zinc and copper makeup, then finally through the lea...

Intro to Chemistry

1)  Chemical changes through chemistry can be seen in our daily lives. (For example, a piece of bread turning to mold, or milk turning souring.) Its very interesting that basic everyday things around us are causing chemical reactions, 2) I found it very impressive that they are more than five types of chemistry including, physical chemistry, organic chemistry, inorganic chemistry, analytical chemistry, and biochemistry. This opens my eyes to how large the world of chemistry is. Organic chemistry- is the study of chemicals containing carbon.  inorganic chemistry- the branch of chemistry that deals with inorganic compounds. Biochemistry- is the study of chemical processes within and relating to living organisms.   physical chemistry- the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems. analytical chemistry- studies and uses instruments and methods used to separate, identify, and quan...
