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. In this experiment an acid-base titration will be used to determine the molar concentration of a sodium hydroxide (NaOH) solution.
Once the sodium hydroxide solution is standardized it can be used to determine the molarity of any acid solution. Consider the following example. A 50.00 mL solution of hydrochloric acid is titrated with a 0.100M solution of sodium hydroxide.The phenolphthalein end point was found at 37.50 mL of NaOH. 25.00 mL sample of HBr is titrated with a 0.150 M standardized sodium hydroxide solution. The endpoint was reached when 18.80 mL of titrant had been added. Calculate the molar concentration of the HBr. A 20.00 mL sample of sulfuric acid (H2SO4) is titrated with a 0.100 M solution of sodium hydroxide.
