Write the balanced chemical equation for the reaction taking place in the flasks for part 1.  From the mass of KHP, calculate the moles of KHP used for each of 3 trials.  Using the moles of KHP in each flask, use stoichiometry to calculate the moles of NaOH that were used to reach the equivalence point in each flask.  Finally, calculate the molarity of your […]

Titration Lab-Finding Ka In this lab you will use an online titration simulation to determine the Ka of two hypothetical weak acids. Step 1: Plan your Lab Write out a purpose, procedure and materials list that you would need if you were going to complete this experiment in a conventional lab. Be sure to include safety considerations in your procedure! You will want to visit […]

Some parts of the paper were worded rather awkwardly, such as “Finding the moles of Acetic acid in the solution by adding sodium hydroxide to the solution in present of phenolphthalein indicator until it reaches equivalence point of the reaction.” I understand what you meant, but it would be better written as something like “The amount of acetic acid in a sample of vinegar can […]

When 0.2235g of strontium reacted with 25.00mL of 1.168 M HCl, 63.18g of H20 (water) was displaced by the H2 gas produced. The temperature in the reaction flask was 27.0 degrees C and the barometric pressure was 777 Torr. The molar mass of strontium is 87.62g/mol. At 27.0 degrees C the vapor pressure of water is 27.0 Torr and its density is 0.9965g/mL. When the […]
