Chemistry Experiments Virtual Labs | How to Implement Them

Last Updated on November 15, 2022 by Sara Assem

Chemistry is a science that revolves around experiments above all else. Chemistry experiments are considered some of the best ways for scientific learning and science investigation and evaluation. So without practical experiments, chemistry can’t be taught.

We can define chemistry experiments as a group of actions and observations done to solve a question or particular problem, to support or falsify a hypothesis or research concerning phenomena conditions.

This is doable by introducing some new variables with the purpose of studying them. Chemistry experiments are also used to train people who need to carry out a chemical or physical phenomenon.

History of Chemistry Experiments

Chemistry as a science depends on using a laboratory and cannot be effectively taught without doing experiments in it.

Doing chemistry experiments in laboratories has a vital role in science curriculums as a means for our young students to make sense of the natural world they live in. Since the 19th century, when schools began to teach science systematically, science laboratories have become a distinctive feature of chemistry learning. 

After the First World War and with rapidly increasing scientific knowledge, science laboratories were used mainly as a means of confirming and illustrating information previously learnt in a lecture or from textbooks.

With the reform in science education in the 1960s in many countries (e.g., CHEMStudy in the USA and Nuffield Chemistry Program in the UK), the idea of science practical work was to engage students in investigations, discoveries, inquiries, and problem-solving activities. In other words, science laboratories became the core of the science learning process (Shulman and Tamir, 1973).

 Types of Chemical Reaction Experiments

There are 5 main types of chemical reactions:

 Types of Chemical Reaction Experiments

  • Synthesis Reactions

It means that reactants combine together (2 or more) to  synthesis  1 new product.


H2O(l) + SO3(g) → H2SO4(aq.)

C(s) + O2(g) → CO2(g)

  • Decomposition Reactions

It means that a single reactant decomposes or breaks down to form 2 or more products.


CaCO3(s) → CaO(s) + CO2(g)

H2CO3(aq) → H2O(l) + CO2(g)

  • Single-Replacement Reactions

It means that a single element replaces a similar element of an adjacent reactant compound.


Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)

  • Double-replacement Reactions

It means that 2 ionic compounds exchange or replace  ions and producing 2 new ionic compounds.


HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

NaCl(aq) AgNO3(aq) → NaNO3(aq) + AgCl(s)


  • Combustion Reactions

It means that a single element or compound combines with oxygen gas and release energy. This oxidation is called burning.


2Mg(s) + O2(g) → 2MgO(s) + energy

C(s) + O2(g) → CO2(g) + energy

Branches of Chemistry

There are five main branches of chemistry:

Branches of Chemistry

 organic chemistry, inorganic chemistry, biochemistry, physical chemistry and analytical chemistry. 

Chemistry branches interferes with physics and biology and it can also interferes with engineering. 

Organic Chemistry 

 Organic chemistry is the study of carbon (that is the main component of any living organisms) and its compounds. It also studies the chemistry of life and reactions of living organisms.  It is also the study of reactions,  structures and properties of  of any compound that contain carbon atom.

Inorganic Chemistry

Inorganic chemistry is the study of inorganic compounds and not covered by organic chemistry ( compounds that don’t contain a C-H bond ).It is the study of properties and behavior of inorganic compounds, including metals, minerals, organometallic compounds ionic compounds, cluster compounds, and solid-state compounds.

Analytical Chemistry

 Analytical chemistry is the study of the chemistry of matter and the development of tools to measure properties of matter. Analytical chemistry includes processes like quantitative and qualitative analysis, separations, extractions, distillation, spectrometry and spectroscopy, chromatography, and electrophoresis. Analytical chemistry is concerned with the study of structure and composition of matter. 


Biochemistry is the study of chemical processes that occur inside living systems like proteins, carbohydrates,  nucleic acids, lipids, drugs, and neurotransmitters. The science of Biochemistry is closely related to genetics, molecular biology and the  biology of cells.

Physical Chemistry

Physical chemistry is the branch of chemistry that applies physics to the study of chemistry, which commonly includes the study of how chemical reactions occur ,also how matter behaves on a molecular and atomic level and the thermodynamics applications and quantum mechanics.

Other Branches of Chemistry You Can’t Miss


There are other branches of chemistry and ways can be divided into categories.

Other examples of branches of chemistry include the following:

Green Chemistry, Chemical Kinetics, Astrochemistry, Nuclear Chemistry, Geochemistry, Electrochemistry, Quantum Chemistry, Polymer Chemistry, Radiochemistry, Theoretical Chemistry and more.

 Chemistry Experiments at Virtual Labs

 Chemistry Experiments at Virtual Labs

The Virtual Lab is a 3D  online simulation of the chemistry lab. The main goal of doing chemistry experiments at virtual labs is to help students link chemical computations with the real chemistry lab. The chemistry virtual lab allows students to perform the experiments in a manner resembling  the real chemistry lab.

Chemistry moves from in-person lab and the classroom to the computer, as working in a virtual chemistry laboratory and viewing simulations provide additional ways of learning chemistry.

Dangers You Need to Avoid in Real Chemistry Experiments

When dealing with hazardous chemicals, there are many ways you could potentially be exposed like through skin, oral ingestion, and inhalation.

Skin and eye contact

When handling chemicals directly, skin and eyes are at risk and careful safety precautions must be taken at all times to minimize risks. The most common complaint of skin contact with chemicals is irritation and burns ranging in severity from mild to severe. Any toxic chemicals can also pass into the bloodstream after contact with the skin.

Oral Ingestion


Inhalation is the most common way for chemicals to enter the body and even the smallest amount of toxins inhaled into the body can be quickly absorbed and cause harm.

Symptoms of exposure to these risks range from irritability, coughing, headache, nausea and vomiting. Depending on the chemical absorbed by the body, it can be fatal and cause permanent damage to organs such as the kidneys, liver, and lungs.

Examples of harmful chemicals

There are examples of the dangerous chemicals you can deal with in the real lab.

  • Organic solvents such as benzene and acetone.
  • Strong acids such as sulfuric acid and hydrofluoric acid.
  • Carcinogens such as toluene and formaldehyde.
  • piranha mix.

If these chemicals come in contact with the skin, it is very aggressive, causing permanent pain and damage. It is also difficult to get rid of them because they will continue to react for a long period of time.

Conducting chemical experiments – especially dangerous ones – through virtual labs avoids exposure to such risks and provides students with a safe work environment
