The course of training at any pharmaceutical institute is impossible without practical classes in chemistry. They are held in the chemical laboratories. Students of our academy carry out various experiments with different chemical substances there.

 All members of my group prefer to attend practical classes. That's why we work in the chemical laboratory with great pleasure. We try to improve our knowledge in practise. Our chemical laboratory occupies a large and light room. It is well-ventilated because chemists often work with substances having strong and unpleasant odour. During our practical classes in chemistry we study chemical and physical properties of inorganic substances. Our students carry out different experiments and carefully record all the findings. Usually they point out the title of the experiment and the date, the substances, describe reagents and the results.

The laboratory has its own equipment. It is equipped with special laboratory tables besides the demonstration table which stands between the two rows of tables and in front of them. In our experiments we use laboratory vessels and glassware of different kinds. There are three groups of them in the laboratory: glassware for general use, glassware for special use and glassware for measuring. Students carry out experiments using test-tubes, funnels, flasks, retorts, burettes, graduated cylinders, measuring glasses and pipettes. They also have microscopes, analytical balances, distillators, burners to heat solutions and thermometers at hand. The most widely available reagents at our laboratory are acids (nitric, sulphuric), alkalis (potassium solution, sodium solution), oxides, organic salts, indicators (phenolphthalein, methylene orange). Among the subjects students study in the laboratory are density, viscosity, vapour pressure and others.

There are a lot of laboratories in our academy. The laboratory of inorganic chemistry is for identifying the properties of elements and inorganic substances. The first-year students have their practical classes there. The qualitative and quantitative analysis of organic and inorganic substances can be obtained in the laboratory of analytical chemistry. The laboratory assistant carries out experiments in the laboratory of organic chemistry. Here we can study the properties of organic substances and ways of their synthesis. There are two more laboratories in our academy: the laboratory of quality control and the laboratory of juridical chemistry. In the latter one students can obtain the toxicological analysis.

The work in the chemical laboratory is of great importance. The findings obtained help people to keep their health and to increase their knowledge. It's well-known that the running water contains various impurities. We learn how to obtain distilled water with distillators. Our students also like to work with special vessels for the determination of molecular weights and for the determination of melting and boiling points.

Summary: Practical classes in chemistry are usually held in the chemical laboratories where students carry out various experiments using different chemical substances. Moreover, the work in the chemical laboratory is of great importance because it helps students to increase their knowledge and to get more practical training.

Exercise 11:Answer the following questions:

1. Where are the practical classes in chemistry held?

2. What do students do in the chemical laboratories?

3. What kind of room does our laboratory occupy?

4. What do students study during our practical classes in chemistry?

5. What is the chemical laboratory equipped with?

6. What groups of vessels and glassware do you know?

7. What do students use when they carry out experiments?

Exercise 12: Make your own short report about your classes in the chemical laboratory.

 
 


Exercise 13:Listen to the song "Lab Safety" and fill in the missing information using the words given below:

 lab experiment without food accidentssafety goggles work through directionseyewash exits

Wait, you've gotta make sure that your lab is safe

Before you make a measurement, scope out the space

Got your gloves pulled up, got your goggles on

Do not want to be another ___ gone wrong

Go with goggles, go with the gloves!

Go ___, and spit out your gum!

Go safe! Go safe! And get into it

Go safe scientists, no ___!

You know the science lab can be a pretty dangerous place

You gotta wear ___ to protect your face

And just in case you still end up with stuff in your eye

You should know how to find the ___ nearby.

And as a matter of fact, know where the ___ are too

'Cause if a fire starts, you better know what to do

And you do not have to be a hero, try to break the mold

Be sure to follow all directions and just do as you're told.

It reminds me of this time I was sitting in lab

Trying to ___ the experiment and give it a stab

When my partner started grabbing chemicals from the shelves

Started mixing up some liquids with unusual smells.

Before he could stop, it began to bubble up

In a couple of seconds he was in deep, deep trouble

So maybe mixing crazy potions did not go as he'd planned

He did not follow the ___ and he burned his hand (ouch!).
