1 If you want to plug in more than one USB accessory at onceâfor example a mouse and a printerâyou can use a USB hub (sold separately) with its own power supply. 2  The power supply thatâs included with Surface Pro models has a USB charging port you can use to power other USB devices while youâre charging your Surface.
Different types of titrations such as acid-base titrations and oxidation-reduction titrations have been utilized in chemical analyses. In this experiment an acid-base titration will be used to determine the molar concentration of a sodium hydroxide (NaOH) solution.Acid-base titrations are also called neutralization titrations because the acid reacts with the base to produce salt and water.ifferent types of titrations such as acid-base titrations and oxidation-reduction titrations have been utilized in chemical analyses.

PART 1 - You prepare a solution of sodium chloride (NaCl) in water to a specified molarity. PART 2 - You obtain a different sodium chloride solution, whose molarity is also known, and you calculate the mass of NaCl contained in a 25.0 mL sample of the new solution.You then measure out this volume, and remove the water from the solution to see if it actually contains the amount of NaCl you calculated.art 2 â Determining the Mass of NaCl in a 25.0 mL Sample of a Solution with Known Molarity. In Part 2, you obtain a different NaCl solution and you calculate the mass of NaCl solution contained in a 25.0 mL sample of the solution.
