Explain what happens in a neutralization reaction.
A base reacts with an acid to form oxygen and a salt.
An acid reacts with a base to form carbon dioxide and water.
A neutralization reaction involves the combination of two acids.
An acid reacts with a base to form water and a salt.
How is the pH scale used to measure acidity and basicity?
The pH scale uses colors to determine the acidity of a solution.
The pH scale measures temperature instead of acidity and basicity.
The pH scale is used to measure acidity and basicity by indicating whether a solution is acidic (pH < 7), neutral (pH = 7), or basic (pH > 7).
The pH scale categorizes solutions as sweet, sour, or salty.
What is the pH range for acids on the pH scale?
2 to 6.99
0 to 8.99
1 to 7.99
0 to 6.99
What is the pH range for bases on the pH scale?
Less than 7
Greater than 7
Equal to 7
Between 0 and 7
What is the pH of a neutral substance?
5
8
7
10
Choose the correct answer for chemical equation on acid-base reaction
Acid + Base gives Salt + Water
