Acid–Base Titration Titration • is a laboratory procedure used to determine the molarity of an acid. • uses a base such as NaOH to neutralize a measured volume of an acid. • requires a few drops of an indicator such as phenolphthalein to identify the endpoint. Core Chemistry Skill ...
Titration Curve A titration curve is a plot of pH vs. the amount of titrant added. Typically the titrant is a strong (completely) dissociated acid or base. Such curves are useful for determining endpoints and dissociation constants of weak acids or bases. Features of the Strong Acid-Strong Base Titration Curve ...
PRECIPITATION TITRATION: It is a titration in which precipitates are formed. One of the reacting species is coverted into a precipitate. Example: Estimation of chloride using AgNo3. Here Agcl is precipitated. cl-+ AgNO -------------- Agcl + No - 3 3 Explanation: When chloride solution is titrated against AgNo3chloride ions are ...
INTRODUCTION Each chemical reaction involves an enthalpy change that leads to change in temperature. The amount of substance converted during the reaction determines the increase (i.e. exothermic reaction) or decrease (i.e. endothermic reaction) in temperature. INTRODUCTION (CONTD.) In thermometric titration, the reagent solution (titrant) is added ...
17.3 Acid Base Titrations •Titrations •Very common analytical test to determine concentrations of unknown solutions •Typically done by adding a known concentration (standardized) of base to acid •Can be done with indicator or pH meter set up to read pH or volts 17.3 Titration ...
ACID-BASE TITRATION Analytical chemistry: is the analysis of material samples to understanding of their chemical composition and structure. It has a wide range of monitoring pollution in the environment, development of new materials, and drug manufacture. Titration technique: Titration is a technique used to determine the concentration of an unknown ...
Titration • In this technique a known concentration of base (or acid) is slowly added to a solution of acid (or base). • The analyte- is the solutions being evaluated and is of unknown concentration. • The titrant is the solution of known concentration used to determine the concentration of ...
Acid-Base Titration The process of adding a strong acid or a strong base to a titrate of acid or base with the purpose of neutralizing the substance in the beaker + - Looking to reach equivalence point mol H = mol OH Acid-Base Titration Generally done with a pH probe ...

Electroanalytical methods Are a class of techniques in analytical chemistry which study an analyte by measuring the potential (Volts) and/or current (Amperes) in an electrochemical cell containing the analyte. These methods can be broken down into several categories depending on which aspects of the cell are controlled and which are ...
Objective: -To study titration curves. -Determine the pKa value of a weak acid. -Reinforce the understanding of buffers. Weak Acid : Weak acids or bases do not dissociate completely, therefore an equilibrium expression with Ka must be used. The Ka is a quantitative measure of the strength of an acid ...
