a process of the concentration of one solution being determined by its reaction with either a standard solution or a known quantity of solid dissolved in solution. It may also be used to calculate the molar mass of an unknown acid or base. Purpose: I. Prepare a standard solution of sodium hydroxide II. Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic ‚ determine the molar mass of

Report: Introduction: The experiment was conducted to find the unknown molarity of HCL. The unknown molarity of HCL was found by the use of the titration method and then comparing the results between the titrant and analyte HCL solutions. Molarity is a concentration unit‚ it is defined by the number of moles the total volume of the solution. This experiment included a process called titration‚ used to work out the unknown concentration of a known substance. The process of titration is adding titrant(known

The Unknown can take the form of anyone‚ anytime‚ or anyplace‚ that feeling you get that makes you uncertain about your future‚ is fear. Fear can be disguised as many other emotions such as anxiety or anxiousness. “Butterflies” do not exist; they are really the fear of not knowing how the immediate upcoming events will turn out or affect you and everyone close to you. There is no such thing as thinking you know something‚ there is simply knowing and not knowing‚ therefore resulting in the fear
