With this tool we can measure a precise volume, and we can know the quantity of the substance we are putting in the beaker. (Manuel Raffa

# data[].attributes.body
It is a particular substance used to make the colour of a substance change, and so to identify what type of substance is. (Manuel Raffa)

# data[].attributes.body
This type of water is used only to dilute the analyzed substance. (Manuel Raffa)

It is anchored on the top of the bubble pipette.

We can use this tool to take a definite quantity of substance, in this case a volume of 20ml.

This is a small magnet that we put in the beaker that is situated on the metallic stir, so it is attracted and it can shake the solution.

MEMBERS:Lorenzo Cammisa, Nicola Coltelli, Federico Fogli.
MATERIALS: to do the calculations, we need a periodic table, a calculator, a pen and a sheet to take notes.
OBJECTIVES: Find the final concentration and the turning point.
OUTCOMES: We have seen the turning of the indicator and we have taken notes of the colour change and concentration of the products. We have found the final concentration.
NOTES:
-Turning: 22,6 mL
-Concentration:(NaOH: 0,1M); (phenolphthalein: 0,1M); ( HCl 0,1M)
CALCULATIONS: v1*c2=v2*c2
c2= 20Ml* 0,1M/22,6(colour change)=0,088mol/L

For a titration experiment we have used : stir, beaker ,burette , a metal support , a small magnet , 1 flask with HCl 0,1 M , 1flask with NaOH  0,1 M , phenolphtalein ( used to make the colour change ), water , Peleus ball , bubble  pipette .
OBJECTIVE : Our objective is to prepare materials and instruments to carry out a successful experiment.
ACTIVITY : we have prepared instruments and the substances to be used on the the work bench neatly .
RESULTS : Our objective has been reached and the other students are now able to perform the experiments.

Baronti, Paduano, Fontana,
Our objective is to perform the experiment.
First of all, we start with the burette.  We put NaOH (Sodium Hydroxide) in the burette, up to zero of the burette scale. Using a graduate pipette, we put 20 ml of HCl (hydrochloric acid) in the beaker adding a little water. We also add 2/3 drops of phenolphthalein indicator.

The beaker is the most used item in a laboratory . It's graduated and is used to make solutions.(battini ilaria)

# data[].attributes.body
The flask below can have  different graduation markings. The most common ones are 100ml, 500ml and 1000ml.

The flask belongs to the laboratory glassware . It is very common and  precise. It containes substances, for example chloride acid as in this photo. (battini ilaria )

4. What happens during a titration experiment?

# data[].attributes.body
In this video we watched a student carrying out a titration. We noticed a change in the colour and we know that it means that the mixture has reached the neutral point. The solution was colourless at the beginning and then it turns into a light pink.  To make a titration we need:

A burette

A beaker

A small magnet

A plate in order to use the stir function.

Follow these steps to do a titration:

1.  Clean the burette with sodium hydroxide (NaOH) and then fill the burette with it.

2. Fill a beaker with hydrogen chloride (HCl) and put a little magnet in.

3. Add just 2-3 drops of indicator in the beaker and open the little stopcock on the burette.

NaOH + HCl → NaCl + H2O

Hi guys, are you hopeless at chemistry? No problem, we are here to help you!
We are the students of 4B of the chemistry course of ITC Cattaneo in San Miniato.
We are in the chemistry lab and we want to explain you how to carry out a common laboratory experiment, "titration". Titration is an analytical method belonging to the classical analysis, whose purpose is to determine the concentration of unknown species by the experimental measurement of the volume of a solution with determined concentration using an indicator and thus determing the equivalence point.
First of all, let's see the materials we need and the steps we must follow to perform the experiment
