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.

Molarity Problems. First kind: Determine the concentration of a solution. What is the concentration (molarity) of a solution made by dissolving 0.20 mol ammonium nitrate (NH 4 NO 3) in enough water to make 500.0 mL of an NH 4 NO 3 solution. Since molarity is just moles per liter if you know how many moles are present in a certain number of liters then you know the molarity. Second kind: Determine the number of moles in a certain volume of a solution of known concentration.
