Given the task definition and input, reply with output. Given a passage and a query based on the passage, generate an unambiguous, concise and simple answer to the query from information in the passage. Note that the answer may not be present in exact form.

An example of titration using phenolphthalein is the titration of vinegar, which is technically acetic acid. When titrating acetic acid, a titrating solution containing a basenormally sodium hydroxideis added to the titrand's solution, which contains phenolphthalein (the indicator) and acetic acid (the acidic titrand). And so we can do our calculation here. So we can take 0.000844, and we can divide that by 0.0200, and we get for our answer here 0.0422 molar. All right, so the concentration of HCl is equal to 0.0422 molar, and we are finally done, right? Just a tiny amount of an impurity in a drug could cause a great deal of harm to a patient. Samples of chemicals that are synthesised must be checked for purity. This is often done by carrying out a titration. A titration is used to measure the volume of one solution that exactly reacts with another solution. Steps of titration. A titration is carried out using a number of steps: If the sample is a solid, it is weighed using an accurate balance, and then dissolved to make up a known volume of solution (usually 100cm3). A pipette is used to measure accurately a volume of this solution - for example, 10cm3. The Titration Experiment Titration is a general class of experiment where a known property of one solution is used to infer an unknown property of another solution. In acid-base chemistry, we often use titration to determine the pH of a certain solution. A setup for the titration of an acid with a base is shown in : Figure %: A titration setup 1 At the equivalence point of a titration, an exactly equivalent amount of titrant has been added to the sample. The experimental point at which the completion of the reaction is marked by some signal is called the end point. In Lab Manual CPAP Titration Optimal CPAP titration Reduces RDI < 5/hour for at least 15 minutes Minimum SaO 2 >90% Supine REM sleep not continuously interrupted by arousals or awakenings All at the selected "optimal pressure" The endpoint mode represents the classical titration procedure: the titrant is added until the end of the. reaction is observed, e.g., by a colour change of an indicator. With an automatic titrator, the sample is titrated until a predefined measurement value is reached, e.g. pH = 8.2 or E = 100 mV. Blank Titration. A blank titration is carried out by titrating a fixed and known concentration of titrant into a solvent with zero analyte. The only difference from the regular titration is the absence of analyte. Scout Titration. 1 Use a pipet to deliver a known amount of the analyte to the appropriate container (usually an Erlenmeyer flask) which has been cleaned and rinsed with distilled water. Members of the sleep team will calibrate the CPAP during a CPAP titration study. The testing process involves the fitting of a CPAP mask and air pressure.
