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
-
-
We will observe the electrical conductivity of several solutions and during dosage reaction using a conductivity-meter
the student have to prepare the relations necessary in the report before the experiment
bring the millimeter paper
-
-
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
-
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.

Experiment 5 : Experimental verification of Nernst’s law
-
We will learn in this experiment how construct electrochemical cells; identify anode and cathode and explain what occurs at each (oxidation or reduction), and measure E0cell for different pairs of metals and metal ion solutions; compare this value by that calculated according to Nernst's law.

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
