Mystery Science: Chemical Reactions and Properties of Matter

Front

What is a chemical reaction?

Back

A process where substances (reactants) change into new substances (products) with different properties.

Front

What are acids?

Back

Substances that can donate protons (H+) and usually have a sour taste.

Front

What is oxidation?

Back

A chemical reaction where a substance loses electrons, often resulting in a change in color or appearance.

Front

What is the pH scale?

Back

A scale that measures how acidic or basic a substance is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What are the properties of metals?

Back

Metals are usually shiny, good conductors of heat and electricity, malleable, and ductile.

Front

What is the role of alchemists in science?

Back

Alchemists were early scientists who tried to transform base metals into gold and discover the elixir of life through experimentation.

Front

What is a base?

Back

A substance that can accept protons (H+) and usually has a bitter taste and slippery feel.

Front

What happens when an acid reacts with a base?

Back

They neutralize each other, producing water and a salt.

Front

What is corrosion?

Back

The gradual destruction of materials, usually metals, due to chemical reactions with their environment.

Front

What is a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved in another (solvent).
