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.
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.The letters pH stand for power of hydrogen and the numerical value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.n pure water, the molar concentration of H + ions is 10 -7 M and the concentration of OH-ions is also 10 -7 M. Actually, when looked at in detail, it is more accurate to classify the concentrations as those of [H 3 O] + and [OH] - .
