Chemical Properties Flashcards
What is the difference between a characteristic and a non characteristic property?
A characteristic property is a property that is unique to a particular substance.
A non characteristic property is a property that several different substances possess.
What are the three states of matter and what are their characteristics?
The three states of matter are solids, liquids and gases.
Solids have the strongest attractive forces which is so strong all the particles stick together.
Liquids still have a strong attractive force, but they are weak enough that the particles slide across each other.
Gases have the least attractive forces. The loss of strong forces allows the particles to crash into one another.
What is the difference between a physical and chemical change?
A physical change is when an atom goes from one substance to another. They are reversible.
A chemical change is when two substances mix together. They are usually irreversible.
What are the three categories of substances?
The three categories are acids, bases and neutral. Acidic substances have a sour tastes and basic substances have a bitter taste. Neutral substances aren’t acidic or basic.
What are the two types of indicators?
The two types of indicators are litmus paper and ph paper. Litmus paper tells you if the substance is acidic or basic an ph paper tells you if the substance is acidic or basic and that level on the ph scale it is.
What is the ph scale?
The ph scale is a scale that classifies the level of acidity and basicity in a substance.
