  • Pratical activity 1

    Buffer solution

    The student must perform all necessary computational operations in the report before entering the lab like:

    -the volume or mass necessary to prepare the solutions

    - the theorical results

  • PW3

    Titration followed by pHmètrie and conducty-meter of citric acid in lemonade

    During this experment, we will learn how to measure using the pH meter and know the pH of drinks.

    the student have to prepare the relations necessary in the report before the experiment

    bring the millimeter paper

  • PW4

    Experiment 4 : determination of alkalinity of water using gran method

    We will calculate the amount of alkalinity in water by titrating the sample water with an acid, using pH-meter.

  • PW6

    Determination of the solubility product of a poorly soluble salt

    We will be possible to manufacture a saturated solution of Ca(OH)2, determine the solubility in pure water and then in a soda solution and determine the solubility product Ks of this salt.

  • PW7

    Experiment 7 : Determination of water hardness by complexometry

    During this experiment, we will determine the calcium and magnesium ion content of a water by complexometry in order to estimate its hardness
