What are salts?
Salts are ionic compounds formed when an acid reacts with a base, typically producing salt and water.
How does pH affect plant growth?
The pH scale measures the concentration of hydrogen ions (H⁺) in a solution, determining whether the solution is acidic, neutral, or basic.
What is the pH of pure water?
Pure water has a pH of 7, which is neutral.
How does a universal indicator work?
A universal indicator changes color depending on the pH of the solution, providing a visual way to determine whether the solution is acidic, neutral, or basic.
What is the pH of a strong acid?
Strong acids have a pH close to 0 (e.g., hydrochloric acid).
What does the pH scale measure?
The pH scale measures the concentration of hydrogen ions (H⁺) in a solution, determining whether the solution is acidic, neutral, or basic.
Can acids and bases neutralize each other?
Yes, acids and bases react in a neutralization reaction to form salt and water, canceling each other’s properties.
Why do acids and bases conduct electricity in water?
Both acids and bases dissociate into ions (H⁺ in acids and OH⁻ in bases), which allows them to conduct electricity.
What do all bases have in common?
All bases release hydroxide ions OH⁻ when dissolved in water and turn red litmus paper blue.
What do all acids have in common?
All acids release hydrogen ions H⁺ when dissolved in water and turn blue litmus paper red.
