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.

Therefore the concentration of H3O+ is twice the molarity of H2SO4 because this holds 2 protons (H+) per mole. So in a 0.007 M solution of sulfuric acid, H2SO4, the concentration of H3O+ is: 0.007 Ã 2 = 0.014 M and pH = -log (0.014) = 1.85 (i.s.o.
