To solve the problem of determining the number of moles of potassium sulfate (K₂SO₄) needed to lower the vapor pressure of water by 10 mm Hg, we can use the concept of colligative properties, specifically the relative lowering of vapor pressure.
Titration is the process of which the unknown solutions concentration reacts with a known solution concentration. During the experiment, titration was used to calculate the moles of HCl neutralized by the antacid in this case was gelusil, by knowing the moles of HCl initially added to the flask...
