- Water is polar.
- Water is an excellent solvent.
- Water has high heat capacity.
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- Water is less dense as a solid than as a liquid.
What are 4 types of chemical properties?
Key Takeaways: Chemical Property Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion.
What are 2 chemical properties of water?
Chemical properties of water
- Amphoteric nature: Water can act as both acid and base, which means that it is amphoteric in nature. Example:
- Redox reactions: Electropositive elements reduce water to hydrogen molecule.
- Hydrolysis reaction. Water has a very strong hydrating tendency due to its dielectric constant.
What is an example of a chemical property of water?
Water undergoes various types of chemical reactions. One of the most important chemical properties of water is its ability to behave as both an acid (a proton donor) and a base (a proton acceptor), the characteristic property of amphoteric substances.
What are physical properties of water?

Which is a chemical property of pure water?
Pure water has a neutral pH of 7, which is neither acidic nor basic. Water is unique in that it is the only natural substance that is found in all three states — liquid, solid (ice), and gas (steam) — at the temperatures normally found on Earth. Earth’s water is constantly interacting, changing, and in movement.
What are 5 chemical properties of chlorine?
Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.
How do you identify chemical properties?
The chemical properties of a substance can be determined by performing experiments that use specific materials or processes with known characteristics. If a material affects the substance in a given way, the substance has a particular property. If a process changes the substance, more properties can be deduced.
What is chemical composition of water?
A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled.
What are five special properties of water?
This article will discuss the five main properties of water: Its attraction to polar molecules. High-specific heat. High heat of vaporization. The lower density of ice.
What are the physical and chemical characteristics of water?
The major chemical and physical properties of water are: water is a tasteless, odourless liquid at standard temperature and pressure. The colour of water and ice is, intrinsically, a very slight blue hue, although water appears colourless in small quantities.
What are some of the special properties of water?
Cohesion, otherwise known as water’s attraction to other water molecules, is one of the major properties of water. Water’s polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together.
What are the chemical elements present in water?
Water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances.
