Titration is a procedure for determining the concentration of a solution. And so let's say we're starting with an acidic solution. So in here let's say we have some hydrochloric acid. So we have come HCl. And we know the volume of HCL, let's say we're starting with 20.0 milliliters of HCl. But we don't know the concentration right? Titrations involve the addition of a known amount of an acid or base to neutralize an unknown amount of acid or base. From the amount of acid needed to neutralize the base, or base to neutralize the acid, one can calculate the pH of the original solution. To detect the endpoint of a titration, an indicator is used.

A titration is an analytical procedure in which a reaction is run under carefully controlled conditions. The stoichiometric volume of one reactant of known concentration, the titrant, that is required to react with another reactant of unknown concentration, the analyte, is measured. Tapering in as small an increment as possible is the safest method, and titration provides the ability to control the taper by minute amounts. Benzos are powerful drugs. A controlled titration minimizes withdrawal symptoms. Titration Procedure Carrying Out A Titration A titration is a process in which a measured volume of a solution is added to a reaction mixture until some observable property has changed. It is a common technique used for measuring amounts of acids and bases, and is then called an acid-base titration. titration (tītrā`shən), gradual addition of an acidic solution solution, in chemistry, homogeneous mixture of two or more substances. The dissolving medium is called the solvent, and the dissolved material is called the solute.

Titration is a commonly applied method of quantitative chemical analysis used to determine the unknown concentration of a solution. A typical titration is based on a reaction between a titrant and an analyte. The titrant of known concentration is gradually added to a precise volume of an unknown analyte until the reaction reaches an endpoint. When appropriate equipment is not available, the method can be performed through visual detection of a titration endpoint, which does not enable an analysis of colored samples. Here, we developed a method with spectrophotometric detection of a titration endpoint, appropriate for moisture determination of colored samples. Nov 05, 2012 · The titration procedure would remain the same since both KOH and NaOH are such strong bases. However, the calculation would change.
