What is the difference between strong acids and weak acids?
Strong acids- produce a lot of hydrogen ions in a solution and break apart completelyWeak acids- produce fewer hydrogen ions in a solution and does not break apart completely
What is the difference between strong bases and weak bases?
Strong bases- produce a lot of hydroxide ions in solution and break apart completelyWeak bases- produce fewer of hydroxide ions in solution and does not break apart completely
What is the pH scale?
A comparison between strong and weak acids and bases in a range 0-14
What are the numbers 0-6 on the pH scale?
Acids- 0-3 are strong acids 4-6 are weak acids
What is 7 on the pH scale?
Neutral
What are the numbers 8-14 on the pH scale?
Bases- strong bases are the numbers 11-14 weak bases are numbers 8-11
What is neutralization?
A chemical reaction between an acid and a base produces a salt
