Titration

Summary
In this lab, students were given the task of finding the percent ionization of the acetic acid, CH3CO2H, in vinegar. Students would slowly add in sodium hydroxide, a base, into the acetic acid until it was neutralized, and showed a pale pink. Materials included a funnel, a burette, beakers, a hot plate, an Erlenmeyer flask, a graduated cylinder, a pippette, and a magnetic stir bar.

Data

Percent Ionization of Vinegar
Our percent ionization of vinegar is 0.45%. This is such a low number because it is a weak acid, so the molecules doesn't seperate easily, and so not all of them split into ions.

The purpose of this lab was to investigate chemical reactions that cause solids to form. Our wellplate of the reactions  Net Ionic Equations What surprised me the most was how quickly the precipitate formed, especially in reaction 6 with NaOH and Cu(NO_3)_2.

Flame Test Lab

Image
Summary In this lab, students were given many different substances to hold over a flame and were asked to observe the colors of the flame produced. This helped demonstrate the relationships of the flame colors and the certain atoms contained in compounds. Pre-lab Questions 1) What is the difference between ground state and an excited state?  Ground state is the most stable state where all the electrons are in the lowest energy levels. On the other hand, an excited state is where the electrons are in an unstable arrangement, and will go back to their normal positions of lower energy. 2) What does the word "emit" mean? The word "emit" means to "produce and discharge", especially in gas or radiation. 3) In this experiment, where are the atoms getting their excess energy from? In this experiment, the atoms are getting their excess energy from the heat of the bunson burner's flame, where the electrons can reach an excited state. 4) Why do

Solubility: A Guided Inquiry Lab

Image
Introduction The purpose of the lab was for students to, using a given graph of solubility, decipher whether an unknown substance is NaCl, NaNO2, or KNO3. Students were not given a procedure, so they had to design their own. Materials included beakers, a hot plate, a balance, a thermometer, a graduated cylinder, and a stirring rod.  Solubility- ability for a solute to dissolve in a solvent Solubility Curve- a graph of the variation of changing temperature of the solubility of a given substance in a given solvent Solute- smaller component of a solution that is dissolved into a solvent Solvent- larger component of a solution that dissolves the solute Solution- liquid mixture where the solute is evenly dispersed in the solvent Saturated Solution- solution containing the maximum concentration of a solute dissolved in the solvent Our Set-Up Procedure 1) We first obtained materials: beakers, a hot plate, a balance, a thermometer, a graduated cylinder, and a
