The pH scale is used to measure how acidic or basic a substance is.
What is an acid?
An acid is a substance which donates hydrogen ions.
What is a base?
A base is a substance which accepts hydrogen ions.
What is the difference between an acid and a base?
An acid donates hydrogen ions, while a base accepts hydrogen ions.
What is an indicator?
An indicator is a substance that changes color in the presence of an acid or a base.
What is the pH of pure water?
The pH of pure water is 7.
What is the pH of an acid?
The pH of an acid is less than 7.
What is the pH of a base?
The pH of a base is greater than 7.
What is a neutralization reaction?
A neutralization reaction is a reaction between an acid and a base, which results in the formation of a salt and water.
What is the difference between a strong acid and a weak acid?
A strong acid completely dissociates in water, while a weak acid only partially dissociates in water.
What is the difference between a strong base and a weak base?
A strong base completely dissociates in water, while a weak base only partially dissociates in water.
What is acid rain?
Acid rain is rain that has become acidic due to the burning of fossil fuels such as coal and oil.
What is a buffer?
A buffer is a solution that can resist changes in pH when small amounts of an acid or a base are added.
What is a titration?
A titration is a laboratory technique used to determine the concentration of a solution by reacting it with a known volume and concentration of another solution.
What is the pH of human blood?
The pH of human blood is slightly basic, with a pH range of 7.35 to 7.45.
