What is the difference between titre and titrant?

The titrant is usually the solution of known concentration that is delivered by a burette into a known quantity of the solution of unknown concentration. The volume of titrant used to reach the end point is termed the titre.
A.

Which one is the titrant?

Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.
  • What is the difference between titrate and titrant?

    A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.
  • What is the equivalence point?

    The equivalence point is the point in a titration where the amount of titrant added is enough to completely neutralize the analyte solution. The moles of titrant (standard solution) equal the moles of the solution with unknown concentration. The equivalence point is not the same as the endpoint of a titration.
  • What is phenolphthalein in chemistry?

    Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments.
B.

What is the difference between a titrant and Titrand?

A reagent, called the titrant or titrator is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand to determine concentration. The volume of titrant reacted is called titration volume.
  • How is an indicator used?

    Acid - Base indicators (also known as pH indicators) are substances which change colour with pH. They are usually weak acids or bases, which when dissolved in water dissociate slightly and form ions. Consider an indicator which is a weak acid, with the formula HIn.
  • What is the meaning of titration error?

    For any titration, the titration error is, by definition, the difference between the volume of titrant added to reach the end point and the volume of titrant necessary to reach a stoichiometrically defined equivalent point.
  • Is the titrant in the burette?

    Yes. When doing a titration, you need to know how exactly how much of the titrant has been added. I suppose you could do it the other way, too, but I have never seen or heard of it being done. If your titrant is in the burette, when you finish one titration, you can simply refill the burette and do the next one.
C.

What is the difference between analyte and titrant?

The equivalence point is when the reactants are done reacting. The solution of unknown concentration is otherwise known as the analyte. During titration the titrant is added to the analyte in order to achieve the equivalence point and determine the concentration of the analyte.
  • What is the difference between the equivalence point and the end point?

    The equivalence point in a titration is the point at which the added titrant is chemically equivalent completely to the analyte in the sample. End point is the point where the indicator changes its color. To get the same equivalent point as the end point, pH of the indicator should match the pH at the equivalence.
  • What is the primary standard?

    Standards are used in analytical chemistry. Here, a primary standard is typically a reagent which can be weighed easily, and which is so pure that its weight is truly representative of the number of moles of substance contained. Features of a primary standard include: High purity.
  • What is phenolphthalein in chemistry?

    Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments.
