Chemistry

• A solution with a pH of 7 is neutral (pure water).
• Acids have a pH less than 7, while bases have a pH greater than 7.
• The pH scale ranges from 0 to 14, where 0 is very acidic, 7 is neutral, and 14 is very alkaline.
• Strong acids completely dissociate into H+ ions when they are dissolved in water.
• Weak acids only partially dissociate into H+ ions when they are dissolved in water.
• Bases can be strong or weak depending on how easily they release hydroxide ions (OH-) when dissolved in water.
