To find the dissociation constant (Ka) of the weak monoprotic acid, we can follow these steps:Step 1: Calculate the moles of NaOH added at the equivalence point At the equivalence point, the moles of NaOH added is given by: \(
For many titration reactions it is possible to find a suitable visual colour indicator that will signal the end point at, or very close to, the equivalence point. Such titrations, classified according to the nature of thechemical reactionoccurring between the sample and titrant, include:acid-base...

The titrant addition is regulated manually and the monitoring of the reaction and indication of the en...
The process, operation, or method of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed, usually as shown by a color change or by electrical...

What is a titration? What is the equivalence point?Titration:A titration is a quantitative technique which is used in chemistry . It is used to determine the accurate concentration of a solution when another solution of known concentration is added in it....
The equivalence point is the point at which the analyte and the reagent are present in exactly the same quantities. In most cases it is virtually identical to the inflection point of the titration curve, e.g. titration curves obtained from acid/base titrations. The inflection point of the cu...
