  1. Titrating sodium hydroxide with hydrochloric acid

    Apparatus for titrating sodium hydroxide with hydrochloric acid to produce sodium chloride. Stage 1. Using a small funnel, pour a few cubic centimetres of 0.4 M hydrochloric acid into the burette, with the tap open and a beaker under the open tap. Once the tip of the burette is full of solution, close the tap and add more solution up to the ...

  2. How to Perform a Titration (with Pictures)

    Swirl the water around a few times before opening the stopcock and allowing it to drain. [2] Repeat the rinsing process at least 3 times with water to completely clean your burette. After you've rinsed the burette with water, perform the same rinsing process at least 2 times with your analyte. 3.

  3. Titration Tutorial: Tips & Tricks for Titrating

    What is Titration? Titration is a method commonly used in chemistry to figure out the amount of a chemical in a solution. This chemical is called the titrand. ... There are many different types of indicators used in titration experiments. Which indicator is used depends on the chemistry of the reaction taking place between the titrand and the ...

  4. How To Carry Out a Titration Experiment

    A titration experiment is the gradual adding of a known concentration of a reagent, called a titrant, to an unknown concentration of an analyte (the substance being analysed) until an endpoint is reached. Titration is one of the classic experiments in chemistry, and it's done by most students at school. Usually, chemical indicators that change colour are used to determine the endpoint of a ...

  7. Simple titration

    We recommend that 14-16 students complete Level 1 of the screen experiment, while older students can progress to Levels 2, 3 and 4. The screen experiments frame the titration procedure with a real-world scenario to foster an interest in chemistry careers and contextualise their learning. This content is provided by YouTube.

  8. Introduction to Titration

    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. ... In this experiment, the titration was performed in triplicate and the mean volume of sodium hydroxide dispensed to neutralize the ...

  9. PDF Experiment 17: Potentiometric Titration

    The equivalence point for the titration of a strong acid with a strong base occurs when [OH-] exactly equals [H3O+] in the solution; pH = 7.0. The situation in the case of the titration of a weak acid with a strong base is somewhat different due to the fact that a weak acid is only partially ionized in aqueous solution.

  10. PDF DETERMINATION OF DISSOLVED OXYGEN BY WINKLER TITRATION

    This procedure describes a method for the determination of dissolved oxygen in aqueous samples, expressed as mL O2 (L water) -1. The method is suitable for the assay of oceanic levels of oxygen in uncontaminated seawater and is based on the Carpenter (1965) modification of the traditional Winkler titration. 3. Definition.

  11. Performing a Titration & Volumetric Analysis

    REQUIRED PRACTICAL 1. Performing the Titration. The key piece of equipment used in the titration is the burette; Burettes are usually marked to a precision of 0.10 cm 3. Since they are analogue instruments, the uncertainty is recorded to half the smallest marking, in other words to ±0.05 cm 3 The end point or equivalence point occurs when the two solutions have reacted completely and is shown ...

  13. A thermometric titration

    In this thermometric titration, students can determine the end-point of the titration using the highest temperature recorded during the experiment. Using a pipette and safety filler, transfer 20 cm 3 (or 25 cm 3) of the sodium hydroxide solution into the cup, and measure the steady temperature. Using the burette, add a small portion (3-5 cm 3 ...

    Acids and Bases - Titrations (A-Level Chemistry) Titrations Titration of Acids and Bases What is Titration? A titration is an experiment through which the concentration of an unknown acid or alkali can be calculated.. When an acid and alkali react together, a neutralisation reaction occurs. If we have an unknown concentration of acid, we can do a titration to see how much acid is needed to ...

  16. How to Write a Lab Report About Titration

    Draw a table to represent the results of your titration. It is customary to write the final burette volume in the first row, the initial burette volume in the second row and the titre in the third row. The titre is calculated by subtracting the initial volume from the final volume. To indicate precision, write all your results in cubic ...

  17. What Is The Winkler Method For Dissolved Oxygen?

    The Winkler method for dissolved oxygen (DO) is a standard titration technique to measure the oxygen content in water. Water is collected in a sample bottle with no air that could interfere with the DO reading. Fixed reagents are added to the sample to form an acidic compound. The sample is then neutralized using a neutralizing compound to ...
