Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

Observation of Different Photons when Elements are Heated Introduction: The bright line spectrum is the range of colorful lights that are emitted from an atom in its excited state. A “normal” atom‚ or an atom in its ground state‚ is when all of the atom’s electrons are in their proper energy level. When an atom is in its excited state‚ electrons jump to different energy levels making them unstable. As the electron tries to get back to its respective energy level‚ energy is emitted in the form
