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.

What is the chemical property of a pure substance?
Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have
the same chemical and physical properties
.
What are the chemical properties?
A chemical property is
a characteristic of a particular substance that can be observed in a chemical reaction
. … A chemical change or reaction is a process in which one substance changes to another substance. In this process, the characteristics of the substances change, and this is when chemical properties are observed.
What is a physical and chemical property?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A
chemical property describes the ability of a substance to undergo a specific chemical change
.
What are 5 physical properties of iron?
- It rusts in damp air, but not in the dry air.
- It dissolves readily in dilute acids.
- At room temperature, this metal is in the form of ferrite or α-form.
- At 910°C, it changes to γ-iron, which is much softer in nature.
- It melts at 1536°C and boils at 2861°C.
- Being a metal is magnetic in nature.
What are the three chemical properties of water?
- Water has a high specific heat. …
- Water in a pure state has a neutral pH. …
- Water conducts heat more easily than any liquid except mercury. …
- Water exists as a liquid over an important range of temperature from 0 – 100° Celsius. …
- Liquid water is a universal solvent.
What are the 12 properties of water?
The main properties of water are its
polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling
. A water molecule is slightly charged on both ends.
What are chemical properties water?
Chemical properties of water involve
parameters such as pH and dissolved oxygen
. Monitoring these characteristics helps to determine if the water meets government regulations and is safe for human consumption and the environment.
What are 3 physical properties?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include
density, color, hardness, melting and boiling points, and electrical conductivity
.
What are the examples of physical and chemical properties?
The
general properties of matter such as color, density, hardness
, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
Is gold a physical or chemical property?
Gold is a
chemical element
so it can only be found, not manufactured.
What are 10 chemical properties examples?
- Reactivity with other chemicals.
- Toxicity.
- Coordination number.
- Flammability.
- Enthalpy of formation.
- Heat of combustion.
- Oxidation states.
- Chemical stability.
What are the 3 chemical properties of matter?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include
reactivity, flammability, and the ability to rust
.
What is a chemical property simple definition?
:
a property of a substance relating to its chemical reactivity
