2. Add 25 mL HCl (of unknown concentration) to the flask. 3. Add 2 drops of phenolphthalein, an indicator, to the flask. 4.Take a burette from the Glassware shelf and place it on the workbench. 5. Fill the burette with 50 mL of 0.5M NaOH solution. Record this initial volume.
Lab Report (not a formal report). Potentiometric Titration of Acetic Acid. The purpose of this experiment was to determine the acid dissociation constant, Ka, of aceticacid from its molar concentration and compare it to the value obtained from its titration.
9.4 ELEMENTS, SYMBOLS AND FORMULAE. Elements are the simple basic substances from which everything else is made. An atom is defined as the smallest particle of an element. An element is defined as a substance that contains only itself - only one kind.
Home > Focus Stories > Honey to heal > Experiment: The viscosity of honey. Experiment: The viscosity of honey. The viscosity of honey ranges from runny to almost solid. In this experiment, you can compare the viscosity of several types of honey.
Chemistry & Biological Macromolecule Name: ______.
a)Two is a crowd for quantum particles, Double slit probes the limits of decoherence. While a single electron will behave as a purely quantum entity, the mere presence of another electron is enough to cause the electron to make the transition from quantum.
15.7Weak acid-Strong base titration. Understanding and Writing Neutralization of Weak acid or Weak Base. In a titration problem, if any titrant has been added, it is critical to consider the neutralization reaction that takes places. This is one of the keys to calculating the pH of the solution.
